1 Overview
1.1 CabinetThe A9130 MFS Evolution hardware consists of an indoor cabinet whichis housed in a telecommunications building. It contains subracks, powerdistribution unit, PBAs, modules and cabling.
The cabinet is designed for buildings with a minimum ceiling height of 2.7meters.
Cable entry to the cabinet can be from:
The topIf the cabinet is mounted on a solid floor, cable ducts in the ceiling carry thecables to the top of the cabinet.
The bottomIf the cabinet is mounted on a raised floor, cable ducts in the floor carry thecables to the bottom of the cabinet.
The cabinet consists of a rack fitted with front and rear doors. When thedoors are closed, the equipment is EMI protected. The doors can be easilyremoved for maintenance.
The arrangement of the subracks in the cabinet takes into account therequirements for:
Thermal cooling, achieved with forced-air cooling
Minimization of floor space
Ease of access for maintenance, from the front of the cabinets
Future system expansion.
1.2 SubracksThe following types of subracks are used in the A9130 MFS Evolution:
ATCAThe ATCA 19" subrack is made of stainless steel.

20 / 112 3BK 21270 AAAA PCZZA Ed.03
2 Cabinet Description
The front upright racking is welded 100 mm from the front door internal face toallow space for cables. The back racking upright position can be adjusted to fitthe depth of the ATCA shelves hosted in the cabinet.
The top of the cabinet can be completely removed (including when cableentry is located at the top of the equipment) to allow easy access for on-sitecabling. It is reversible (front to back) to allow access from the left or right sides,depending on the configuration. For a corner installation, part of the installationkit is bolted to the racks using the ring hooks of the cabinet, therefore allowingthe use of a vertical cable guide.
The following facilities are provided for site cabling:
When cable entry is from the bottom, a rectangular pipe is installed on
each side, between the front and the back upright racking, to easily allow
14 power cables (14 mm in diameter ) to be fed from the bottom to thetop (seven on each side)
When cable entry is from the top, these pipes are used to feed 32 PCMcables (9 mm in diameter and equipped with a 12 x 66 mm connector) from
the top to the bottom (16 on each side). In this case, up to six Ethernet
cables (8 mm in diameter) can also be fed through these pipes.
The bottom of the rack has three windows for bottom cable entry:
One window at the front, covering the complete usable width of the
JSXLIU/JSXLIUB shelf and dedicated principally to PCM cables access
One window on each side, under the pipes, used for power cables routing incase of bottom access and for PCM cables routing in case of top access.

3.1.5 Connection to the Hosted Shelves
Each ATCA shelf is connected to the JSXPDU via eight 16 mm2 wires (7mm indiameter).
Each JSXLIU/JSXLIUB shelf is connected to the JSXPDU by two 7 mm (three1.5 mm2 wires ) cords, including the ground.
3.1.6 Earthing Connection
The building’s ground is connected to the JSXPDU by a double stud. Thisearthing conductor is distributed to the JSXLIU/JSXLIUB shelves through thepower cord, and to the mechanics of the cabinet via a double stud. A specificlabel is added near the connection of the earthing conductor.
3.1.7 Safety
The JSXPDU meets the EN 60950 safety standards. Branch A and branch B arebe independently protected by two separate covers so that service personnelcan safely access one power branch when the other branch is operational.
3.1.8 Provision for Future Use
In the case where an alarm function will be added in the JSXPDU, a free spaceof approximately 25 mm width of the whole height (2U) is reserved betweenboth branches A and B. The front plate is bored with a column of five 4mmholes. These holes will be hidden by the label which covers the whole frontpanel and bears the marking.

3.1.10 Power Distribution Cable Characteristics
3.1.10.1 ATCA Shelves SupplyingThe power entry on ATCA shelves is done via 6 mm studs. The power cablescoming from the JSXPDU shelf are terminated by lugs rings.
The cable used is a two wire, 16 mm2 cable. The blue wire corresponds toVBAT. The black marked wire corresponds to the Battery Return.
The required cable lengths are:
1.5 m for the upper ATCA shelf
2.1m for the second ACTA shelf.
30 / 112 3BK 21270 AAAA PCZZA Ed.03
3 Power System
3.1.10.2 ATCA Shelf GroundingThe ATCA grounding point is a double lug, spaced at 19 mm. The 16mm2
yellow/green ground cable is terminated by a lug with two holes.
There are two possibilities for the ground connection:
One cable between each ATCA shelf and the JSXPDU (same length aspower cable), or
The frame of the cabinet is used as ground, and the JSXPDU and the ATCA
shelves are connected to the frame by a cable.
3.1.10.3 JSXLIU/JSXLIUB Shelf Supply and GroundingThe power connection on the JSXLIU/JSXLIUB shelves is done through threepin UP connectors. The connector is composed of a moulding and threecontacts.
3.2 CoolingThe JSXATCA shelf provides fault tolerant cooling to front mounted AdvancedTelecom Computing Architecture (Advanced TCA) blades, and to rear transitionmodules based on four front-maintainable, intelligent fan trays, with one fanper tray.
Blower trays are mounted in the shelf top. The following figure shows thegeneral airflow for the ATCA system. The cooling type is front to rear.
Air Inlet
Air Outlet
Front Rear
Blowers
Figure 8: Shelf Airflow
The cooling system is designed to manage a heat dissipation of 200W perfront slot and an additional 20-30W per rear slot.
Each of the fan tray units contains an IPMC, which is located on both theIPMB-A and IPMB-B buses. Individual fan failures are detected by monitoringthe fan rotation speed. Rotation which is 15% below demand is deemed to be afan failure. Usually the cooling system runs the fans at 40%. In the case of a
3BK 21270 AAAA PCZZA Ed.03 31 / 112
3 Power System
single fan failure, the fans run at 100% to still provide full air pressure within thearea between the fans and the boards.
Each fan tray monitors and reports air temperature and failure conditions to theshelf manager. The shelf manager controls the fan speed based on sensorand failure information acquired from the fan and board sensors. If a fantray looses IPMI communication with the shelf manager, it will automaticallyrun the fans at full speed.

4 ATCA Shelf
4.1.1 Shelf
The 13U (577 mm) and 440 mm deep shelf for 19" racks is made of stainlesssteel.
There is one mounting bracket on each side of the shelf, designed forfront-mounting the shelf into a rack.
The system can be installed in a standard 19’’ rack.
4.1.2 Node Slots
The node slots are equipped with Advanced TCA blades.
Advanced TCA blades used in MFS configuration are the followinghigh-performance, single slot, hot-swap node boards:
JBXOMCP
JBXSSW.
Advanced TCA blades offer a high processing performance. They are idealfor telecommunication applications.
4.1.3 Hub Slots
The hub slots are equipped with JBXSSW switches. The JBXSSW is a GigabitEthernet switch.
4.1.4 Rear Transition Modules
The Advanced TCA blades can be connected to Rear Transition Modules(RTM) to provide easy access to I/O signals through the zone 3 connectordefined by the Advanced TCA specifications.
RTMs can be used as a rear expansion board for the JBXSSW switch to accessthe different interfaces on an AdvancedTCA blade through the JAXSSWfront plate.
4.1.5 Power Entry Modules
Four field hot-swap intelligent JBXPSs with a 50 Amp breaker and line filterare installed beneath the rear slots of the backplane. The four JBXPSs areused to provide split power distribution. For details about the JBXPS refer toJBXPS (Section 4.8)
4.1.6 Power Distribution System
The shelf has two different power distribution systems that run throughout theshelf. The first is a low power (3.4VVDC) system that provides power to all ofthe IPMCs. The second is a high power (-48VDC) system that provides powerto all of the blades, blowers and shelf managers.
36 / 112 3BK 21270 AAAA PCZZA Ed.03
4 ATCA Shelf
4.1.6.1 Low Power Distribution SystemThe shelf’s low power distribution system powers the IPMCs engines. Thislow power source (3.4V DC) manifests itself in the form of a redundantinterconnect. The first (V_A) is sourced from the JAXSMM in the J3 location.The second (V_B) is sourced from the JAXSMM in the J11 location. The IPMCsare expected to OR the two sources to allow for redundancy. Current on eachsource is limited by the 2 mm connector to approximately 1.5 A.
The inclusion of the low power distribution system is to allow for powering theIPMCs without having to include an isolated DC-DC and all of its relatedcircuitry in each IPMC. This is most useful in FRUs such as the blowers andJAXPCs, where their size essentially prohibits the inclusion of such powerconversion circuitry.
The voltage from the power distribution system can also be found on theoptional IPMC expansion connectors found throughout the shelf.
The following figure shows the low power distribution system found in theJBXPS shelf.

The first redundant interconnect is made up of the A1 and B1 feeds. The firstfeed (-48V_A1) is sourced from the A1 JBXPS in the far left (as viewed from therear of the shelf). The second feed (-48V_B1) is sourced from the B1 JBXPS tothe right of the first one. Both feeds are individually routed to each JAXSMM,blower and odd numbered slots. The second redundant interconnect is madeup of the A2 and B2 feeds. The third feed (-48V_A2) is sourced from the A2JBXPS (to the right of the B1 JBXPS). The fourth feed (-48V_B2) is sourcedfrom the B2 JBXPS (to the right of the A2 JBXPS). These feeds only route tothe even numbered slots. In both interconnects, the FRUs are expected to ORthe two sources to allow for redundancy.
The A1 and B1 JBXPS locations are capable of supplying 90 A of current,although the JBXPSs will only allow for 50 A. The A2 and B2 JBXPS locationsare capable of supplying 50 A. This allows for a single JBXPS in eachinterconnect, to support the full power requirement of the interconnect.
For the blowers, the A1 and B1 feeds are capable of supplying 12 A whenderated for a 30� C temperature rise. For the JAXSMMs, the A1 and B1 feedsare limited by the 2 mm connector to approximately 1.5 A (per feed).
4.1.7 Blowers
The system provides fault-tolerant cooling by using four front accessible,hot-swap intelligent fan trays. Each fan tray contains one blower with built-inspeed control. A toggle switch is provided to allow supervision interruptionfor maintenance reasons.
4.1.8 Shelf Manager
The shelf manager (JAXSMM) is designed to be used in Advanced TCAsystems. It is the central management unit of the shelf. It monitors, controlsand ensures the proper operation of the shelf and all other components ofthe Advanced TCA shelf.
It reports anomalies and errors and takes corrective actions if required (e.g.increases the speed of the blowers). The JAXSMM has access to detailedinventory information as well as to sensor status information concerning theshelf and all the components of the shelf.
4.1.9 Personality Card
The personality card (JAXPC) is a shelf configuration and alarm board usedwith AdvancedTCA systems. The JAXPC personality card is designed for rearaccess applications. It is located below the Rear Transition Module (RTM) area.

4.5 JBXGPU
4.5.1 Introduction
The JBXGPU board is installed in the MFS equipment designed to handle theGeneral Packet Radio Service (GPRS) in the BSS.
The MFS:
Receives Ater links from BSCs, carrying a mix of circuit (voice) and GPRSpacket channels
Transparently forwards circuit channels to the MSC through another Aterinterface
Processes GPRS packet channels and forwards them to the SGSN, directly
or through the MSC, on a Gb interface.
The Ater interface has an E1 structure (2,048 Mbit/s), with a 64 or 16 or 8kbit/s sub-channeling.
For Gb interface, there are two posible configurations:
FR over E1, E1 structure bearing Nx64 kbit/s channels, each of which carry
GPRS packets on Frame Relay links
IP over Ethernet
The Ater and Gb interfaces can be on the same link between the MFS andthe transcoders.
The SGSN performs similar functions as the MSC in GSM, such as trackingindividual MS locations and providing security functions and access control.
The MFS equipment is housed in a new platform, based on standard AdvancedTCA shelves. The main shelf contains :
Two redundant shelf managers (JAXSMM) performing management
through redundant IPMI busses
Two redundant switches (JBXSSW) performing mainly Gigabit Ethernet
switching at the shelf level
Two redundant Operation and Maintenance Control Processing boards(JBXOMCP) in charge of telecom control, and providing large capacity
storage
Up to 10 JBXGPU boards in one shelf and up to 22 JBXGPU boards incase of two selves configuration.

4.6 JAXSMM
4.6.1 Introduction
The JAXSMM is a 2U shelf manager board used in AdvancedTCA systems. Itplugs into a dedicated shelf management slot of an advancedTCA system. Theboard provides management for up to 16 advancedTCA front blades as well asfor blowers, power entry modules, alarm modules, and shelf FRU info modulesthat are used in an advancedTCA system. In a redundant configuration theJAXSMM are used as redundant shelf manager.
The JAXSMM is a main component of the shelf management system. The shelfmanagement system is used in AdvancedTCA systems and its purpose is toensure proper operation of AdvancedTCA blades and other system componentslike blowers, power entry modules (PEMs) and rear transition modules (RTMs).
The shelf manager board possesses a backplane connector and is pluggedinto a 2U slot.
The alignment protrusion offers a guide rail to the slot and a coding mechanismto ensure the installation of the board in the matching slot. It also prevents bentpins, which can occur during installation.

4.6.2 Payload Hardware
The payload hardware on the shelf manager board is always powered whenpower supply is present. During power on, the JAXSMM keeps the payload in areset state. The following interfaces are available:
Three Ethernet interfaces
Two redundancy interfaces (serial)
Block transfer interface.
4.6.2.1 Ethernet InterfacesThe shelf manager board has three Ethernet ports which are availableconcurrently.
One 10/100 BaseT out-of-band interface is accessible via a RJ45 connector atthe front plate. Link and activity status LEDs are integrated into the connector.
Two 10 BaseT interfaces are connected to the backplane connector at the pinsEth1-Hub Tx/Rx and Eth2-Hub Tx/Rx.
These ports connect to the base interface of up to two AdvancedTCA switchboards (e.g. SSW) in the hub slots of an AdvancedTCA shelf.
The green LEDs (Ethernet LEDs) on the front plate indicate the link status ofthe Ethernet ports.
4.6.2.2 Redundancy InterfacesJAXSMM uses a private, redundant, high-speed, full duplex serial connectionfor heart beating and data replication between the two shelf manager boards.
The redundancy interface is routed to the backplane via differential line LVDStransceivers. The physical interface of both channels are compliant with theAdvancedTCA specifications for the update interface.
Each of the serial inputs of the redundancy interface triggers an interrupt to thePowerQUICC when the other shelf manager board:
Initiates a break-in condition on the serial line
Experiences a power failure
Switches in the reset state
Is extracted.
66 / 112 3BK 21270 AAAA PCZZA Ed.03
4 ATCA Shelf
4.6.2.3 Block Transfer InterfaceThe payload CPU is connected to the JAXSMM via a parallel interface withinterrupt support implemented in a FPGA.
The block transfer (BT) interface is compliant with IPMI specification v1.5.
4.6.3 Shelf Management Controller
The JAXSMM part is derived from IPMC building block and consists of twocoupled microcontrollers:
IPMC master controller (IMC)
IPMC Slave Controller (ISC).
4.6.3.1 IPMB0 InterfaceIPMB0-A is connected to the I2C controller of the IMC.
IPMB0-B is connected to the I2C controller of the ISC of the JAXSMM. Bothhave their own I2C controller and handle message transmission and receptionindependently, including bus error handling and bus arbitration.
Received messages from both the IMC and the ISC channels are collected bythe IMC. The IMC dispatches messages which have to be sent either to itsown I2C interface or to the ISC for transmission.
4.6.3.2 IPMC Standard FunctionsThe following functions of the IPMCs are available on the IPMC of the JAXSMM:
Hardware address input from the backplane connector (HA 0 ...7)
Handle switch.The handle switch is generally activated by a lever which moves when oneof the front plate fastening screws is loosened or fastened.

5.2.2.1 Power SupplyThe board is powered from two separated +12 V inputs. The + 3.3 voltageis obtained via a non isolated converter (the isolation is performed on theJBXPEM board). The 1.5 voltage required for the JGXESD FPGA is providedvia a linear regulator.
5.2.2.2 Line InterfaceThe JBXLIU/JBLIU75 provides 16 balanced 120 or unbalanced 75 E1lines, compliant with G.703.
The line interface is provided by two octal E1 short hall JBXLIU/JBLIU75s inthe PBGA package. These LIUs are associated with four octal transformersensuring the galvanic isolation.
Tripolar protection is provided on the PCB to prevent difficulties with regard tomeeting K41 requirements. It is assumed that if this protection is not required, itwill not be equipped.
5.2.2.3 LIU Reference ClockFor clock recovery and jitter attenuation, the E1/T1 LIU needs a 2048 kHzreference clock when used in E1 mode, and a 1544 kHz reference clockwhen used in T1. In order to permit the dual mode, two crystal free runningoscillators are implemented on the board. On the current board, only the 2048kHz oscillator is equipped.
3BK 21270 AAAA PCZZA Ed.03 93 / 112
5 JSXLIU/JSXLIUB Shelf
5.2.2.4 E1/T1 ConfigurationThe LIU functions are as follows:
In the ingress direction:
Clock recovery
HDB3 decoding
LOS detection.
In the egress direction:
HDB3 encoding
Jitter attenuation.
The configuration of the LIU is achieved via the non-multiplexed bus typeemulated by the JGXESD. Depending on the configured mode, the LIUreference clock is switched to 2048 kHz or 1544 kHz. In the current design,the JGXESD only provides E1 capability. This configuration is downloadedinto the LIU upon hardware reset.
The LIUs are configured as follows:
AIS disabled on LOS
LOS criteria is G.775
HDB3 coding enabled
Jitter attenuator depth 32 bits
Jitter transfer bandwidth 1.7 Hz
Jitter attenuator in transmit path.
In the egress direction, the JGXESD extracts the orders of local or a remoteloop-back on each E1 link from the serial link. It transfers these orders into theLIU loop-back configuration register. In the ingress, it reads the loop-back andLOS status registers of the LIU and inserts the information in the serial link.
5.2.2.5 JGXESD Reference ClockThe JGXESD component requires a 36864 kHz transport clock for the 4B/5Brecovery clock function. It is provided via a VCXO used in free run mode.
5.2.2.6 JBXMUX SelectionDepending on the status of the SELA input, the E1 or T1 output signal comesfrom the serial link A or B. This function is performed inside the JGXESDcomponent. The link A is active when SELA is low.
In the ingress direction, the 16 E1 are converted and sent on both serial links.
5.2.2.7 Stuffing33 bytes of payload are allowed to each E1 or T1 link every 125 ms. Dependingon the phase relationship between each line clock and transport clock, these33 bytes carry 255, 256, or 257 bits. This function is performed inside theJGXESD component.

5.2.2.10 Remote InventoryAn EEPROM with I2C access is dedicated to RI data. It can be read by theJGXESD component. A specific connector allows the factory to write thedata when the board is not powered.
5.2.2.11 Board PresenceA pull down indicates the presence of the JBXLIU/JBLIU75 board to theJBXMUX boards. The active JBXMUX board can reset the JBXMUX boardby driving this access high.
5.2.2.12 Hot InsertionThe JBXLIU/JBLIU75 board can be plugged into the JSXLIU/JSXLIUB shelfwithout perturbing the other boards of the shelf.
5.2.2.13 ESD Discharge CircuitAn ESD discharge circuit allows a progressive discharge of the board beforecomplete insertion.
5.2.2.14 Start PolicyThe board starts when powered ON.
5.2.2.15 Reset PolicyThe board is reset at power ON, or by the active JBXMUX by PRSET access.
The LIU can be reset through the serial egress link.
5.2.2.16 Boundary Scan Chain (JTAG)The boundary scan chain includes the JGXESD and the two octal LIU. Thechain is accessible on a dedicated connector for factory use. For futureimprovements, a “Firecron“ scan path component is implemented (notequipped). This component can provide access to the boundary scan chainfrom a backplane bus reserved for this application.

5.3.2.1 NE1OE BlockThe nE1oE function constitutes the main part of the JBXMUX card and ishoused in the JGXEOE FPGA. This function provides, along with the E1interface/ alignment/ Mux function setting on each LIU card, an overall E1cross-connect capability for 512 E1 PCM links (limited by hardware capabilitiesto 256 E1 links) over Ethernet transport.
The nE1oE can be split into the following sub-blocks:
16E1 data interfaces 4B-5B codingEach of the 16 serial data links in connection with the 16 LIU cards inthe shelf are 4B-5B coded/decoded for reducing the backplane accessconnector pin-count and ultimately simplifying the backplane physicaldesign. The nominal bit rate before coding is 36.864Mbps and the linebit-rate is 46.08Mbps. Data out and data in signals are conveyed to/fromeach LIU card after single to differential signal conversion (100 Ohmbalanced pairs), ending up with a two pair backplane interconnection perdata stream. Data and synchronization signals are recovered from the 4B5Bcode itself via an over-sampling technique.
Ethernet frames packing/ unpacking and E1 cross-connect with physicalentities within the MX platform perimeter (JBXGPU, JBXOMCP)
Gb Ethernet MAC/Physical interfacing, with auto-negotiation 10/100/1000base-T with Reduced Pin count GMII (RGMII) interfacing on the MAC side
Communication with the second JBXMUX card for mutual active/ standby
switching-over process control
Control and user plane management to/from the Gb Ethernet link.
3BK 21270 AAAA PCZZA Ed.03 99 / 112
5 JSXLIU/JSXLIUB Shelf
This part is achieved by an embedded processor (SOC) also in charge ofthe SDRAM, the Flash, the I2C, the RS232 debug link, the in-band resetand shelf address management.
5.3.2.2 Timing GenerationNE1oE Master clock: The designated active JBXMUX card in theselected JSXLIU/JSXLIUB shelf is by definition also the master, in terms ofsynchronization for the entire nE1oE function on the MX platform. As a result,all other entities present in the system are necessarily synchronized with the8kHz rhythm sent by the JBXMUX through the nE1oE framing mechanism.
A 36.864MHz VCXO used as a free run oscillator is dedicated to this end, andprovides the clock signal used by the JGXEOE as the reference for all nE1oEsub-blocks. The 8KHz frame synchronization signal is also internally builtfrom this reference.
Given that the JGXEOE architecture is common to the different applications(JBXGPU or JBXMUX), the internal PLL tracking is disabled in the JBXMUXcase and the phase comparator output pulse width is set to its mid-range value.An analog low pass filter (cut-off at approximately 10Hz) provides the VCXOwith a DC voltage, setting the output frequency to its mid-range value.
System clock: A 25MHz system clock signal is produced by a free runoscillator for the JGXEOE, the JGXCLU and the GbE transceiver. TheJGXEOE Mac interface sub-block uses the 25MHz input clock to produce the125MHz reference clock necessary for the 10/100/1000base-T application. Thefrequency multiplication is managed via an internal broadband PLL embeddedin the FPGA matrix. The same artifact is used on the transceiver Mac side.
5.3.2.3 Ethernet Physical Interface ModuleThe gigabit Ethernet physical access is performed via the Marvell 88E1111transceiver. This transceiver use a Reduced pin count GMII (RGMII) interfacewith the JGXEOE, and has its MDI interface connected directly to an1000base-T RJ45 module integrating the filtering magnetics and two LEDs .
RGMII interface:
Upward: TXD[3:0], TXEN, GTX CLK
Downward: RXD[3:0], RXDV, XCLK.
For alarm collection and register programming, the transceiver TWSI interfaceis also connected to the JGXEOE.
5.3.2.4 Active/ Standby CommunicationIn the 1+1 protection scheme philosophy adopted on the MX platform, theactive/ standby switchover provides a very important function of the JBXMUX. Itgives each of the 16 LIU cards in the shelf clear information as to which of theincoming data streams (from either JBXMUX card A or B) is the valid one.
The active/ standby communication link concerns the two JBXMUX cardspresent in the JSXLIU/JSXLIUB shelf as part of a shared RS flip-flop function).This function provides each JBXMUX with an exclusive mechanism fortriggering one JBXMUX in Active or Standby modes, whereas the secondJBXMUX is automatically set to the opposite state.
Switchover triggering events:
100 / 112 3BK 21270 AAAA PCZZA Ed.03
5 JSXLIU/JSXLIUB Shelf
Master request from the MX platform management entity. The order isreceived from the JBXOMCP through the Ethernet and is decoded as such
by the JGXEOE control plane management.
Card in error (see below).
These two events are processed in an autonomous fashion vis-a-vis the MXplatform management entity. In both cases, a report of the JBXMUX statechange is sent to the MX platform management entity through the Ethernetcontrol frames.
A JBXMUX card is declared in error after any of the following events:
Card currently in reset mode (nE1oE functions are unavailable until the end
of this sequence)
FPGA download sequence NOK (monitoring of JGXEOE init done signal
along with watchdog time-out) or card absent
Boot operational status not validated (specific bit and watchdog time-outmonitoring)
No supervision frame received for more than n X T seconds, whereby T =
mX100 ms and n is a positive integer.
5.3.2.5 Flash Memory BlockThe Flash memory contains the FPGA configuration files and the boot code ofthe processor embedded in the JGXEOE.
The Flash is accessed via a data path of 8 bits wide at a frequency of 12,5MHz. The Flash is performed with two components (8Mx8 (M29DW640Dfrom ST, 70ns access time).
The Flash is split in two main areas
A permanent area programmed in the factory (write protected)
An update area which can be programmed by the SoC processor.
The programming process is controlled by the JGXCLU EPLD but the updateconfiguration is managed by the embedded processor of the JGXEOE FPGAand is received through the Ethernet communication.
5.3.2.6 SDRAM Memory BlockThe SDRAM is used by the SoC processor to store its executable programand eventually to store data (constants, variables) if the JGXEOE internalmemory is not sufficient.
The SDRAM capacity is 512 Mbits. It is organized in 16 Mega words of 32bits each and is accessed via a data bus of 32 bits at the frequency of theprocessor (i.e. 66 MHz). The SDRAM memory is built with two 16Mbit*16memory components.
5.3.2.7 RS232 Test InterfaceConnected to the JGXEOE, this serial interface provides test access through adedicated RJ45 connector setting on the front plate.
Communication port settings:
Speed : 115200 baud

Parity : No
Data bits: 8
Stop bit: 1
Flow control: No.
5.3.2.8 LIU Cards Presence DetectionThe JGXEOE is in charge of collecting, via the I2C interface, card presenceinformation for each LIU card slot in the JSXLIU/JSXLIUB shelf. In order to doso, a I2C decoder able to manage 16 I/O is used (PCA9555) to detect the 16signals PRST_1 to 16 present on the backplane connectors.
LIU present: PRST_xx = Voltage logic level low (LVTTL)
LIU absent: PRST_xx = Voltage logic level high (forced on the JBXMUX cardinput by a pull-up resistor to 3.3V).
5.3.2.9 I2C InterfaceA single master I2C interface managed by the JGXEOE is used to communicatewith the :
RI component (EEPROM 512X8, 10ms)
JBXPEM in the JSXLIU/JSXLIUB shelf (local RI and alarms polling)
External components in charge of detecting the JBXLIU/JBLIU75 board’spresence.
For the different I2C items to be accessed properly, each item of the sametype (i.e. RI EEPROM, temperature controller, I2C GPIO) have a uniquehardware address code within this type.
5.3.2.10 Reset LogicTwo types of reset are implemented on the JBXMUX:
Power-ON resetThis is a global hardware reset of the entire card. A power supplysupervisory circuit supervisor monitors the main power supply rail (3.3V).As soon as it reaches a certain threshold, it maintains the JGXEOE, theJGXCLU and the GbE transceiver (PHY) in reset. As soon as the JGXCLUreset is released, it performs the JGXEOE download operation from theFLASH down to the FPGA. As soon as the JGXEOE bit stream is loaded,the component “Init-done” signal is activated and the JGXEOE master resetis released, followed by the boot loader execution
JBXMUX resetThis is a single reset bit carried out by the nE1oE control frames. It isalso used as a global hardware reset for the JBXMUX card. This resetbeing conveyed by the FPGA, which is a target for this reset action, theFPGA JBXMUX reset output falling edge is detected and converted into acalibrated negative pulse driving the power supply supervisory circuit(MAX708S) responsible of delivering the master reset pulse. A discretecomponent (TLC7701) is responsible for performing this function.

5.3.6 Power Supply Description
This block is responsible for converting the incoming 12V A and 12V B DCvoltages to the following DC voltage rails:
+3.3V / GND powers the RAM, the Flash, the JGXCLU, the JGXEOE I/O,the ISPPAC and all the discrete components
+1.5V / GND is for the JGXEOE core
+1.2V / GNDis for the GbE transceiver core
+2.5V / GND is for the GbE transceiver I/O and the JGXEOE I/O.
5.3.6.1 TNV/ SELV Galvanic IsolationThe incoming 12V rails are provided by each JBXPEM card in theJSXLIU/JSXLIUB shelf. The -48V to +12V DC/DC converters used for this
3BK 21270 AAAA PCZZA Ed.03 105 / 112
5 JSXLIU/JSXLIUB Shelf
purpose feature a galvanic isolation between the two classes of voltageshandled in the system. For this reason, the DC/DC converter block used onthe JBXMUX card does not have to exhibit any galvanic isolation, therebyreducing its overall cost.
5.3.6.2 Power Supply ManagementA specialized IC monitors and controls each secondary power supply voltagerail used by the card:
Card plug-in (hot insertion) whereby all the secondary voltages rails areenabled at the same time and a smooth start is programmed to limit the
inrush current
DC rail voltage failure, whereby any secondary power supply rail whose
voltage value is below 10% of its nominal value ( factory programmable
threshold) triggers a global disabling of all the secondary rails.
5.3.7 Safety
The JBXMUX board belongs to the JSXLIU/JSXLIUB shelf, and meets thesafety specifications, according to the LIU Product Integration QualificationSpecification:
The Gigabit Ethernet access is TNV1 voltage class
Other circuits are SELV voltage class.
Mechanical ground and logic ground are kept separated on the board. Thesetwo ground types can be connected together at the backplane level by additionof dedicated screws.
With regard to the ESD discharges for the front plate and the electrical groundplanes. The Compact PCI standard [16] ensures a soft discharge of anyhazardous ESD buildup by the use of 3 copper stripes laid down the PCB card,and one metallic card guide clip placed within mechanical rails in the shelf.When the card is plugged into its slot, the stripes are successively in contactwith the clip, ensuring an electrical path towards the mechanical ground.
Consequently, the front plate is connected to stripe 1 (nearest to the front plate)through a 10M Ohm resistance, the ground planes are connected to the secondstripe, and the third stripe (nearest to the back side) connects the front platedirectly to the mechanical ground (no resistance).
This is shown in the following figure.

5.4 JBXPEM Board
5.4.1 Introduction
The JBXPEM board handles the power for the JSXLIU/JSXLIUB shelf. EachJBXPEM receives front input from - 40V up to - 72 VDC, redundant A + Bpower feeds. Each JBXPEM board distributes the +12VDC supply to theJBXLIU/JBLIU75 and JBXMUX boards. The global consumption is less than100W (fully loaded).
The JBXPEM board is part of the JSXLIU/JSXLIUB shelf, which belongsto the MX platform.
The JBXPEM board is hosted in the JSXLIU/JSXLIUB shelf in slots 1 and 21.Each JBXPEM board receives -48/60 VDC on the front panel. The redundantfunction between both JBXPEMs is provided through the backplane.
This is shown in the following figure.

5.4.2.1 Hot Insertion DeviceThe JBXPEM board can be plugged into the JSXLIU/JSXLIUB shelf withoutdisturbing the other boards in the shelf. A specific device suppresses theinrush input current.
5.4.2.2 EMI FilterAn EMI filter is required in order to be compliant with the 73/23/EEC directive,to obtain the CE marking label.
5.4.2.3 48V / 12V ConversionTwo incoming separated input power supplies feed each board:
Front input -48/60Vdc
Back panel input -48/60Vdc (VBATI).
12 V power supply is distributed by each JBXPEM to all the other boardsvia a complete plan.
P12VA is the +12 voltage generated by the left JBXPEM. It is connected toP12Vi on the right JBXPEM.
P12VB is the +12 voltage generated by the right JBXPEM. It is connected toP12Vi on the left JBXPEM.
5.4.2.4 12V /3.3V ConversionThe 12V to 3.3V conversion is made by a bipolar low drop device to feed thelogical alarm supervision. The regulator is powered by two 12V. The first is thelocal 12V of the JBXPEM and the second is the 12V of the second JBXPEM.
5.4.2.5 Hardware ManagementA multi-master I2C interface, managed by the JGXEOE of the JBXMUX,is used to communicate with the:
RI component (EEPROM 512X8, 10ms)
JBXPEM in the JSXLIU/JSXLIUB shelf (local RI and alarms polling)
108 / 112 3BK 21270 AAAA PCZZA Ed.03
5 JSXLIU/JSXLIUB Shelf
External components in charge of detecting the JBXLIU/JBLIU75 boards’presence.
Each item of the same type (i.e. RI EEPROM, temperature controller, I2CGPIO) has a single hardware address code within this type.
Slot Address: Each slot in the JSXLIU/JSXLIUB shelf backplane is individuallyidentified by a specific polarization of the SLA signals. “X” indicates thatthe jumper is present and drives the corresponding SLA pin of JBX* board.When it is left open, the selected board will detect a logical level “1” via anadequate pull up resistor.
The address number of the JBXPEM board is:
1 for JBXPEM A
21 for JBXPEM B.
RI EEPROM: An EEPROM with I2C access is dedicated to RI data. It can beread by the active JBXMUX board component. A specific connector allows thefactory to write the data when the board is not powered.
Alarm Collection: The different alarms come from:
-48/60Vdc of JBXPEM board A
-48/60Vdc of JBXPEM board B
12V
The temperature sensor.
All the alarms are connected to a I²C/SMBus device. This I2C link allows theJBXMUX to read the RI EEPROM, the alarm register and the temperature onthe adjacent JBXPEM board. It is composed of the SCL and SDL signals.Arbitration of the I2C master is performed via active/standby signals.
Temperature Sensor: The LM75 temperature sensor provides the localtemperature at all times to the JBXPEM board. When the temperature exceeds80�C, the device generates a temperature alarm.
5.4.2.6 Redundant A+B Power FeedThe VBAT power supply enters the front panel of each JBXPEM on left andright sides of the shelf . It is also distributed to the other JBXPEM board. TheVBATO of JBXPEM A is connected to VBATI of JBXPEM B (and reciprocally).
Each JBXPEM board generates 12V (A & B). All the other boards are poweredby two 12V:
P12VA from JBXPEM A
P12VB from JBXPEM B.
5.4.2.7 ESD Discharge CircuitAn ESD discharge circuit allows a progressive discharge through a resistor(10 MW) on the board before complete insertion.
