SW versions interoperability

BS-BU with version 5.30 can interoperate with TS-BU with the following SW versions: 4.10 4.20 4.50 5.00 5.30

TS-BU with version 5.30 can interoperate with BS-BU with the following SW versions: 4.10 4.20 4.50 5.00 5.30

BS Version 2.08 does not support Terminal Stations with version 4.20 or higher

In such a configuration the TS will not be able to synchronize on the BS and will continue the Frequency scan. Upgrading to version 4.20 should be done according to the following procedure: Download the new version to all Terminals. Verify correct version download in all

Terminals. Download the new version to the BS. Verify correct version download to the BS. Switch all Terminals to 'standby' version.

At this point, the Terminals will reset and start performing the frequency scans. Switch BS to 'standby' version.

Once the BS is powered up, make sure all the previous Terminals are (re) connected.

Authorized managers table Ver 3.11 → 4.20

When switching the software version from 3.11 to 4.20, the authorized managers table content is being erased


iv

Rx/TX Cable gain during update Ver 4.0 → 4.20

In SW version 4.0 there was a problem of switching between TX and Rx cable gains. This bug was fixed in version 4.20. While upgrading WALKair from version 4.00 to 4.20 a User that switched the cable gain must switch the Tx/Rx cable gain back.

Required actions when upgrading from versions earlier than 4.00.

Enable all Services. Service configuration is kept when upgrading from version 2.08 and up.

Loop back settings are not kept when upgrading to version 4.20. Active Loop back should be re-configured.

Upload/download configuration in version 04.20 and 04.50

Once configuration download was finished, the BU must be reset. Upload and download at this point are permitted but they are illegal operations and could damage the configuration parameters

BS-BU revision B BS-BU units from HW Rev. B00 and up should be loaded with Software version 3.11 and up.

Redundancy feature can be activated only on BS-BU from HW Rev. B00 and up.

BS-BU revision C BS-BU units from HW Rev. C00 and up should be loaded with Software version 4.2 and up.

Version 5.3 Features

1


Ethernet WALKair 1000's Ethernet port implementation leverages WALKair 1000's FR functionality towards the CPE. WALKair 1000's Ethernet port encapsulates the outgoing packets and de capsulate the incoming packets with the FR RFC1490 IP Route encapsulation. Multiple DLCIs can be assigned to the Ethernet port, up to 250 DLCIs at the Base Station and up to 30 at the Terminal Station.

Packets coming from the Ethernet interface are sent over the air through the different PVCs using two mapping mechanisms: VLAN based DLCI mapping and source/destination IP subnet DLCI mapping.

Frames that arrives from the air are transmitted by the Ethernet interface to the connected device containing VLAN tags, or not, according to the source DLCI.

Configurations

WALKair Ethernet is implemented using a 10/100BaseT-interface card. The Ethernet traffic is translated to Frame Relay protocol and transmitted from the Base Station at peak rate of up to 4Mbps.

WALKair supports the following network scenarios.

Table 3:Eternet Configuration Options

The Ethernet interface supports 10/100BaseT interface according to IEEE 802.3 standard. The Maximum port rate is 10Mbps/100Mbps auto sensing. RJ45 connector is implemented with NIC connector.


2

NOTE: An FR interface at the BS, configured with peak rate of 4 Mbps, can operate only with 4 Mbps Ethernet/FR cards at the TS. If there is a 2 Mbps card at the TS, the Ethernet interface card or the FR interface at the BS must be configured as 2 Mbps.

Figure 1 describes a possible network architecture including a BS with an Ethernet card and Terminal Stations with Ethernet, FroE1 and Frame Relay interfaces.

Physical Interface 10/100BaseT interface is complied with IEEE 802.3 standard.

RJ45 connector is used for Ethernet port.

Maximum port rate is 10Mbps/100Mbps.

Peak traffic rate over the air is 2Mbps or 4Mbps (configurable). 2Mbps is the default value.

Routing - FR Translation

WALKair 1000's Ethernet port checks each Ethernet frame from the LAN that bears its MAC address and determines the destination DLCI according to the source subnet or VLAN. WALKair 1000 encapsulates the packet as a RFC1490 IP and sends it towards the air using a predefined DLCI-Subnet or DLCI-VLAN tag-mapping configuration.

IP packets received from the FR network in RFC 1490 IP format are forwarded over the air and de-encapsulated from the FR header. They are then assigned an Ethernet header according to the ARP table and forwarded towards the LAN.

Multiple DLCIs can be assigned to the Ethernet port in this way. The user can configure the preferred routing e.g. according to either VLAN tagging or subnets.

VLAN Tag/DLCI Mapping

WALKair 1000 Ethernet port supports VLAN tagging according to 802.1Q.

IP Packets coming from the LAN towards the air are stripped from the Ethernet headers, encapsulated with FR headers according to the RFC1490 IP and assigned to the appropriate DLCI, according to their tags.

IP packets coming from the air towards the LAN are stripped from the FR headers, encapsulated with Ethernet headers and assigned VLAN tags according to the source DLCI.

VLAN tag/DLCI mapping is manually assigned by the management system.

WALKair 1000 supports 250 tags at the Base Station and 30 tags at the Terminal Station that can be mapped to 250 or 30 DLCIs accordingly. Each VLAN tag has 64 entries in the ARP table.

Subnet-DLCI Mapping

IP packets coming from the LAN towards the air are stripped from the Ethernet headers, encapsulated with FR headers and assigned to the appropriate DLCI, according to their source/destination subnets.

IP packets coming from the air towards the LAN are stripped from the FR headers, encapsulated with Ethernet headers and forwarded towards the LAN.


5

Source IP Subnet/DLCI mapping is manually assigned by the management system.

WALKair 1000 supports up to 30 subnets per Ethernet port at the Terminal and 250 subnets at the Base Station.

TS- Router Spoofing

The Ethernet port at the TS simulates a static router, with no IP address of its own. This eliminates the need for additional router-related configuration and IP addresses. The IP stations on the LAN are configured with a default router that resides in the backbone. However, the Ethernet MAC address associated with this IP address is the Ethernet port MAC address. Consequently, all traffic destined outside the local IP net is directed to the Ethernet port, which simulates some of the router functions, as follows:

The Ethernet port assumes the IP address of the central router. Since multiple DLCIs (up to 30) can be supported, several default routers may be configured on each Ethernet port.

ARP Spoofing: ARP requests issued by IP stations in the LAN while sending messages to local IP address, and addressed to the default router, are replied by the Ethernet port with its MAC address.

IP Forwarding: Packets destined for the default router are forwarded towards the air by the Ethernet port. Since the Ethernet port returns its MAC address as the default router MAC address, IP stations send all non-local traffic to the Ethernet port.

VLAN support: Up to 30 VLANs are supported on the Ethernet port, using the 802.1Q standard.

DLCI support: Up to 30 DLCIs are supported per Ethernet port, towards the air.

DHCP/BOOTP Relay: The TS forwards DHCP/BOOTP messages towards the DHCP server, in order to enable the dynamic addressing scheme. DHCP/BOOTP messages that are destined for the originating station are forwarded towards the LAN, using the originator's MAC address.

NOTE: DHCP/BOOTP messages can be forwarded only in VLAN mode, since there is no source IP address in this case.


6

Base Station ARP

WALKair Ethernet port will support ARP according to RFC 826 standard.

ARP Reply

The BS Ethernet card replies to ARP requests for any IP address on one of the subnets configured for this card, in case the DLCI associated with this subnet is in operation status active.

ARP request containing VLAN tag for any IP address replies by the Ethernet card, in case this VID is configured for this card and it’s associated DLCI operation status is active.

In both cases, only ARP requests from the Default Gateway, which is configured for this DLCI, are replied.

ARP Table

Separate ARP tables are kept for each VLAN on the Ethernet port. Each table actually contains one entry (for the default gateway).

Additional tables for non-VLAN address will have a size of 250 entries.

The address of the station originating the ARP request (which is the Default gateway IP address) will be added to the ARP table if a reply is sent.

ARP table entries will be kept for 20 Minutes after their last use.

ARP Request

WALKair Ethernet port initiates ARP request towards the LAN when a packet arrives from the air, which has an IP destination address that doesn’t exist in the ARP table. In the special case of the Ethernet port on BS, where the only destination IP address is the one of the default gateway for every DLCI, an ARP request with the default gateway’s IP address will be issued (if required).

An ARP request for packets coming from a DLCI associated with a VID will contain a VLAN tag.

ICMP support

WALKair Ethernet port issues a “Net Unreachable” Message towards the air when a message is send to IP address different from the default gateway, and ARP Reply is not received from LAN. The source IP address in these messages will be an address from the destined subnet that is different from the default gateway address.

NOTE: When a message is send to default gateway, and ARP Reply is not received, No ICMP message is sent.


7

IP Broadcasts/Multicasts

The BS Ethernet port forwards all IP broadcast and multicast packets towards the air, only if the source IP address is of the default gateway.

In the VLAN the IP broadcast/multicasts packets from the air are transmitted over the LAN with the appropriate MAC address.

BOOTP/DHCP Handling

The BOOTP/DHCP messages receive no special treatment.

NOTE: In order to receive the DHCP replay messages as a broadcast, the broadcast field in the DHCP request must set first. This should be done in the TS side.


8

QBRI Functional Description The WALKair QBRI card solution provides up to 4 Basic Rate U ISDN interfaces at the Customer Premises side. Such an interface card is required in a Multi Dwelling application serving several customers who each require a small number of ISDN interfaces.

The QBRI interface is implemented in a single slot at the TS–BU, Each U interface of the QBRI functions fully independent of the other U interfaces. The supported line coding is 2B1Q. The BRI traffic is carried and concentrated over V5.2 protocol.

At the Base Station, the BRI overV5.2 is carried towards the backbone using an E1 interface.

The QBRI feature allows the customer to connect up to 2 QBRI cards per TS, which allows the support for a total amount of 8 U lines (2 QBRI cards per TS) or to a PABX or NT1, which is located in the CPE. The reason for the limitation of 2 QBRI cards per CPE is that the Power feeding module only supports up to 2 QBRI cards per TS.

The QBRI feature allows the operator to deliver POTS and ISDN-BRI services to the end user customer. By connecting a Network Terminator (NTBA or NT1+2a,b) to the U interface, it is translated into S Interface or POTS Analog a,b lines.

WALKair implementation complies with the following standards:

CCITT Recommendation I.412, I.420

CCITT Recommendation G.823

Configuration

WALKair 1000 supports the following network scenarios:

At the CPE side, the Terminal Station supports one or two QBRI interface cards.

At the Network side, the Base Station supports an E1 interface card with V5.2 software. Two E1 cards are installed at the BS-BU in order to support Primary and Secondary Signaling protection.

Each BS-BU is a single V5.2 interface to the public switch.

The BS-BU V5.2 software includes V5Core (AN side, V5.2) and a set of V5 applications.

A V5.2 Voice Switch with ISDN & PSTN package is mandatory for the describe feature.

The 2*64Kbps payload is transmitted in band while the Signaling (D Channel) will be transmitted out of band in the EOC.

Two E1 cards are connected at the BS-BU, Primary and Secondary.


10

Signaling Multiplexing ISDN BRI signaling is transferred out of band via the Embedded Operation Channels (EOC).

For the downlink direction (from the BS to the TS), each received signaling message is routed and transferred to its corresponding TS. At the TS, the signaling message is directed to the appropriate QBRI and U interface ports.

For the uplink direction, each signaling message is transferred, as is, to the BS-BU via the EOC channels. At the BS, signaling is routed and directed to the V5.2 interface.

Signaling messages are routed using the following user port identifiers:

L3 address / EF address and interface ID at the BS V5.2 interface

TS customer ID

L3 address / EF address / BRI port number and Interface ID at the TS QBRI interface

The destination address parameters of the message header are changed (interface ID and L3/EF address) as a result of the routing process.

Voice Traffic Multiplexing

Voice traffic multiplexing is performed by transferring a voice channel between a specific bearer channel in one of the BS E1 ports and another specific channel at a corresponding TS QBRI port. The association between bearer channels at the BS E1 port and TS QBRI port is fixed at the TS interface and dynamic at the BS V5.2 interface.

Voice Traffic Concentration

Voice traffic concentration is the capability to allocate air bandwidth only for active circuits. V5.2 protocol supports concentration by definition, meaning that the association between the user port and bearer channel on the interface is not predefined. The bearer channel is allocated dynamically, on demand. This functionality is provided by the V5.2 Bearer Channel Connection (BCC) protocol of the interface. BCC controls dynamic allocation/releasing of time slots for the interface according to demand. Dynamic air channel allocation/release is performed by the BS software, and is triggered by input from the BCC protocol.


11

Control and Maintenance

Each Interface has two types of interface status:

Administrative status: A result of explicit management action, with two possible values, Enable and Disable.

Operational status: The current state of the interface, with two possible values, In-Service and Out-of-Service.

The administrative status determines the desired status of the interface. If the administrative status is changed to enable, then the operational status changes to In Service as a result of successful interface re-initialization, and the interface is then ready to transmit and receive traffic. It remains in the Out of Service state only if there is a fault that prevents it from successful re-initialization. If the administrative status is Disable, the operational status must be Out of Service.

BS and TS interface statuses are independent of each other. The status of the TS interface does not affect the status of the BS interface, and vice versa. However, the TS/BS status affects the status of the ports.

The QBRI port has only one status attribute, operational status, which is determined by the interface status. Administrative status is not determined per port, but rather per interface. The public switch or CPE can control the operational status of the port. In general, the WALKair 1000 V5 application is responsible only for routing an appropriate request (block/unblock) from the BS to the TS and vise versa. However, the V5 application may trigger Port Block/Unblock in the following situations:

If changing the administrative status of a specific TS QBRI interface to Disable causes the interface to shut down.

If changing the administrative status of the V5.2 BS interface to Disable causes the Out Of Service operational status to shut down. The V5 application blocks the relevant ports of the TS QBRI interfaces. After service resumes, WALKair 1000 invokes port unblocking.

Air Link Loss (ALL)

The ALL blocks the relevant user port at the BS V5.2 interface and shut down the relevant QBRI interface. After the air link is re-established, WALKair 1000 unblocks the ports at the V5.2 interface and re-establishes the TS QBRI interface.


12

Restrictions

The following restrictions apply:

Packet (FR and X25) over D channel is currently not supported.

128 Kbps bonding is currently not supported.


13

QBRI Feeding Module The QBRI Feeding module is part of the QBRI feature and is essential for most of the common NT’s connected to the U Line at the Customer Premises.

Figure 3:QBRI Feeding Module

The Power Feeding Module is able to deliver 102VDC and up to 60mA in order to operate the Network Terminators that can be located even a few hundreds of meters away from the Terminal Station.

There are a few types of NT, which can be operated only with the 2B1Q U line signal, provided from the QBRI card but they are not the commonly used ones.

The Feeding module is an external device composed of well-known Power Design module units. The Feeding Module receives the outputs of the QBRI card, a 2B1Q line code signal (+1V, -1V, +3V, -3V) and combines the signal with a DC signal of 102VDC / up to 60Ma.

The combined signal in accordance with ETSI standard will allow proper operation of the NT’s.

3.5GHz Rasters Description

In order to allow the operator to utilize the maximum allocated spectrum, and due to the fact that allocated spectrum is different from one market to another, three spectrum rasters could be used.

Each of the three rasters determines the RF channel centers in 1.75MHz spacing steps.

Raster 1 and Raster 2 are shifted in 0.875MHz from each other.

Raster 3 has an additional frequency index added to raster 2 as shown on: Figure 5: 3.5GHz Up Link Rasters and Figure 6: 3.5GHz Down Link Rasters

Figure 6: 3.5GHz Down Link Rasters

The BS transmits (and receives) in a manually configured raster via LCI or NMS. The Factory default is Raster 1.

The terminal stations automatically synchronize and establish a link with either rasters.

When Air linked is established and BS was configured with raster 2 or raster 3 a display to the TS screen will be:

“Sync on RF Band with index (N-1) of raster 2 = N of raster 3 in frequency [frequency up, frequency down]. “

If raster 1 was selected in the BS the TS display will be: “Sync on RF Band with index in frequency [frequency up, frequency down]. “

NOTE: Whenever switching rasters the BU must be Disabled and Enable in order that the new raster will be active.

Variable Operating Point - VOP Introduction

Originally, the approach in WALKair system was to use a fixed Rx operating point at BS (up-link) for all the terminals.

The received signal was determined once at the moment of commissioning the BS-BU and for all the Terminal Stations connected to this specific carrier.

The link quality in this case was determined by the most distant TS, if this TS can reach the BS with a maximum power level of –84 dBm, then all the rest of the terminals should adapt their transmitted power in order to be received at the BS also at –84 dBm.

The new mechanism allows a dynamic or variable operating point to each one of the terminals connected to a specific BS-BU, the received power will be according to the distance between the TS and the BS, this new feature will improve the quality of the link of most of the terminals while distant TS will still keep a reasonable link quality.

VOP Mechanism

The mechanism that cope with free space loss and flat fading is the Remote Terminal Power Control (RTPC), this mechanism assure that the received power at the Base Station is according to the value defined in the Rx modem working point.

When working with VOP, the RX level parameter at the BS is inactive; the actual Rx power level will be determined according to the following parameters:

The distance of the TS from the BS

Additional fading of the RF path

The saturation curve of the TS

The maximum receiving power of the BS

VOP starts its operation by requesting from each one of the TS connected to a specific BS-BU to start transmitting power at such a level that the received power at the BS will be –84 dBm, then, gradually the mechanism will try to increase the received power by asking that from the TS, the upper limit of the Rx power is –76 dBm.

This VOP process tuning is about 15 min. long.

While trying to get more power from the Terminal Station, the VOP mechanism will examine continuously the saturation curve of the TS in order to keep the required back off from saturation levels, this back off is defined by the 64 QAM modulation method.


18

Close terminals will be able to reach the BS at the upper limit allowed by VOP and by this will achieve a better C/I and as a result of it a better fade margin.

Distant Terminals or Terminals installed in difficult conditions will not be able to reach the BS with such a large margin but in case they can reach the Base Station above the lower limit they will still be able to allow the link with the required C/I for a BER of 10-9.

An additional advantage of VOP is the capability of transmitting more power from the TS than the defined in the nominal value. This is permitted because of the continuous examination of the saturation curve of the terminal station.

The VOP mechanism has impact on uplink performance (especially C/I uplink) therefore the network planning tool should support uplink power control simulation.

VOP user interface

To enable better radio planning, the user can control the operation of the VOP feature, individually per terminal by the TS LCI or for all TS’s by the BS BU LCI/NMS.

Two parameters exist in the BS/TS BU:

Administrative Status – Indicates the administrative status of the feature, disable/enable. Enabled status will look for hardware compatibility at the BS BU and the TS BU and if the right conditions found the feature will operate. The user can control the administrative status.

Operational Status – Up, indicates that the feature is in operation. Down – indicates that the feature didn’t find the right conditions to operate, either its administrative status is disabled or there is no hardware compatibility. The operational status is read only.

NOTE: Disabled VOP at the TS will take place 5 minutes after link initialization; the uplink power level will increase from –84dBm to the configured working point.


19

VOP Utilization In Small Cells Deployment

VOP feature is optimized for cells sizes greater than 5 km; in cells smaller than 5 km this feature may be disabled (not mandatory) according to the next instructions:

Normally, all terminal stations within the radios of a planned cell, will be connected to this cell.

In case of a relatively further terminal from the cell coverage and it has to be connected to a service, the next instructions will assist to give a temporary service for that customer:

The Tx power of the relevant BS-BU should not be less than 18dBm. Note that n+1 adjacent channel power can be up to 15dBc to assure BER of 10e-9.

Enable the VOP at the BS BU and in the far terminal.

VOP operation example

With VOP

1. Rx1=-80dbm , C/I+N= 25 dB

2. Rx2 = -78dbm , C/I+N= 27 dB

3. Rx3= -76dbm , C/I+N= 29 dB

Figure 7: VOP Operation Example

The example above shows two scenarios of VOP operation in 3.5GHz cell:

With VOP – VOP is enabled.

Without VOP – VOP is disabled.

It can be seen that the VOP improves the C/I of most of the TS’s while it still keeps the link with the TS1, which is installed in the edge of the sector.


20

Requirements for Operating VOP

At Base Station:

The VOP is able to work on BS BU only when the following requirements are met:

BS BU revision from V5 on

SW version from V4 on for 3.5 GHz and from V5 for 10.5 GHz and 26 GHz

At Terminal Station:

The TS requirement for VOP enable on BS (for that specific TS) is:

SW version from V4 on.

NOTE: If a TS MUX is in use and configured, automatically the VOP will be disabled for the TS.

Management Control

The enabling/disabling control button of the VOP options is available from Ver 5.1 at the BS-BU window. In order that the changes will take place the BS-BU must be reset.

Local Craft Interface commands

VOP enabling/disabling can be done from the LCI under “Modem Maintenance Menu”.

On previous versions to 5.1 the only way to disable the VOP is by running a specific script at the Base Station.

BS - Tx and Rx Modem Working Point Introduction

According to the international standards, Alvarion recommends transmitting a certain nominal power per each carrier according to the carrier band. However the user can define the optimal Tx power according to the cell deployment. In this case the user will receive the following message:

“The Tx power is out of the recommended range. Are you sure you want to exceed this range?”

The new value will be affected after the user confirmation.

Whenever the inserted value matches the recommended values, the values will be set without the warning message.

Frequency Band

Recommended Tx Range

3.5 GHz: 12 – 18 dBm.

10.5 GHz: 9 – 15 dBm.

26 GHz: 4 – 10 dBm.

Table 5: Recommended Tx Power according to the frequency band

The Rx power can be set only within the recommended values of -84dBm to -70dBm.

PD-LPM-0102EPDSL LTU POWER MODULE: 36-72VDC INPUT, DUAL 120VDC/60mA OUTPUT

PD-LPM-0102EP

FEATURES ♦ Designed for Span Powering of ETSI HDSL Systems ♦ High Efficiency ♦ Input to Output Isolation ♦ Two Outputs with Independent Protection Mechanism ♦ Outputs can be Paralleled for Current Sharing, i.e. 120V/120mA ♦ Adjustable Output Voltage (105 to 120Vdc) ♦ Wide Input Voltage Range ♦ Output Unbalanced Indication ♦ Five year warranty ♦ UL1950, CSA22.2-950 and EN60950 Approved ♦ Backward compatible with the PD-LPM-01021

APPLICATIONS ♦ HDSL/xDSL Systems ♦ Voice Pair-Gain Systems ♦ Supports Single and Dual Loop Configurations ♦ General Remote Power Feeding Communications Applications ♦ 48Vdc, 60Vdc Telecommunications Systems ♦ ETSI Remotely Fed Systems

DESCRIPTIONThe PD-LPM-0102EP is a 15 Watt DC/DC converter module especially designed for HDSL/xDSL remote power feeding applications (on LTU).The module operates from 36 to 72Vdc input voltage and provides two independent balanced outputs of 120V/60mA, isolated from the input.The output voltage can be reduced, in the range of 105-120V, by adding an external resistor. Reduction of the output voltage to 105-120V maybe required in order to allow for HDSL communication signal superimposing, without exceeding the maximum 120V standard limitation. A highprecision current limiting circuit is implemented on each output. This feature enables delivery of maximum power through the line whilemaintaining the TNV safety requirements of maximum 60mA current. The module also provides report lines, which deliver informationregarding unbalanced outputs (deviation of more than 20%) and overload condition of each output. The overload protection circuits on eachoutput are independent, and allow for one output to work normally while the other is overloaded. The PD-LPM-0102EP is designed to workoptimally while working in conjunction with the PowerDsine PD-NPM-03xx module series. Designed for ETSI specific requirements, thePD-LPM-0102EP simplifies integration and reduces overall system dimensions, cost and time to market.

NOTES1. Outputs Overload 1 and Overload 2 are designed to drive 1mA for an opto-coupler LED (no additional resistor is needed). High

impedance load on this terminal may develop high voltage up to 120Vdc.2. Outputs Unbl. and Unbl. RTN are designed to drive 1mA for an opto-coupler LED (no additional resistor is needed). High impedance load

on this terminal may develop up to 13Vdc.3. Unless otherwise stated, data refers to both Output 1 and Output 2.4. Connecting a resistor, Rext, between pin 6 and 8 sets the output voltage. For output voltages of 110V, Rext = 11.5KΩ resistor. When left

open (Rext = ∞), the output voltage is set to its maximum value. Setting effects both Output 1 and Output 2.5. The output stage acts as a current source. When output current reaches the threshold, an overload circuit will detect 5-8V drop below the

nominal set value.6. The output stage acts as a current source when it reaches the current limit level. When output voltage falls below a threshold level, the

output stage is disconnected in order to reduce heat dissipation. The unit reverts to normal operation once the overload condition isremoved. Overload condition on one output does not effect the other output.

7. The module is designed to meet EN55022 Class B Standard with an external EMI filter. For filter design recommendations, refer to thePowerDsine xDSL Power Modules Application Note.

8. When connecting the two outputs in parallel to achieve a single 120V/120mA output, automatic recovery from overload shutdown willoccur only after the total consumed output current drops below 60mA.

SAFETY INSTRUCTIONS (According to UL1950, CSA C22.2 No. 950 and EN60950 requirements)1. For North America, input voltage (nominal 48Vdc, tolerance 36-60Vdc) must be applied by isolated DC source complying with the earthed

SELV or TNV requirements of the UL1950, Third edition.For other countries, input voltage (nominal 48Vdc, tolerance 36-72Vdc) must be supplied by isolated DC source complying with theearthed SELV or TNV requirements of the latest version of EN60950.

2. DC input must be protected by UL Listed fuse rated maximum T2.5A, 250V (slow-blow 2.5A, 250V fuse).3. When applicable, protection from excessive voltage on the output should be tested in end-use equipment.

PIN CONNECTIONSPin # Function Description

1 120V Output1 RTN Output power ground #1.2 120V Output1 Output power #1. To ensure proper operation under large load changes, a minimum 10µF Aluminum

electrolytic capacitor in parallel to a 1µF film capacitor must be connected.3 Earth GND Pin 3 should be connected to system GND. Output power is balanced in reference to pin 3.4 Overload 1 Report line, active when output #1 is in overload or short circuit condition. See Note 1.5 Overload 2 Report line, active when output #2 is in overload or short circuit condition. See Note 1.6 Voltage Adjust Connection of a resistor between pin 6 and 8 enables reducing both output voltages simultaneously in the

range of 105-120V. The resistor needs to be 1/8W rated or higher.7 Earth GND Pin 7 should be connected to system GND. Output power is balanced in reference to pin 3.8 120V Output2 Output power #2. To ensure proper operation under large load changes, a minimum 10µF capacitor

(electrolytic or other) must be connected.9 120V Output2 RTN Output power ground #2.10 -48V RTN Positive Input line connection.11 -48V Input Negative Input line connection.

12,13,16,18 NC Not connected.

14 Unbl. RTN Return line for Unbl. See Note 2.15 Unbl. Report line. Active when output voltage (either or both) become unbalanced in reference to the GND

Ground. This may occur when there is an unwanted current path to ground (leakage). Note 2.17 Inhibit Logic input, referenced to the -48V input (Pin 11). Voltage above the specified threshold will inhibit the

operation of the unit, and current consumption on input will drop to a very low level. Leaving this inputunconnected or tied to a low logic level will enable the unit.
