7549 WMG Chassis

Power filter

- The 7549 chassis is a mid-plane design- All card slots (front and rear) are same height/depth- Front card slots are used for Control, Voice Server, Echo Server cards- Rear card slots are used for TDM matrix and Network Interfaces

(TDM, ATM and Ethernet)- Rear side of chassis also contains two half-height Shelf Interface (SI)

cards for Ethernet control plane, BITS, test access ports, console

Packet and Control (PAC) Card

The PAC is at the top of the control hierarchy of the gateway. It provides management and control of all gateway resources with the cooperation of the other processors in the gateway node. The PAC supports control interfaces for controlling the other cards in the chassis.

The PAC serves as the call processing interface of the gateway to the controlling MGC. It performs narrowband signaling for the signaling types handled by the gateway.

Each PAC provides two external 100Base-T Ethernet (FE) interfaces for communications with the controlling MGC, providing a total of four FE interfaces for the gateway that appear on the Shelf Interface.

MandatoryTwo per Media Gateway (1:1)


Switch, Service, and Timing (SST) Card

The Switch, Service and Timing (SST) card provides TDM DS0 channel switching capability for the 7549 Gateway. There are two SST cards in a chassis, configured as an active/standby (1:1) redundant pair, which plug into two dedicated center slots in the rear of the chassis. The SST card also provides service circuit resources for call processing, and supplies reference clocking to the other cards in the gateway chassis.

The SST card contains a 64K x 64K TDM matrix, or Time Slot Interchange (TSI) matrix.

MandatoryTwo per Media Gateway (1:1)


Gigabit Ethernet Interface

The Gigabit Ethernet Interface (GEI) card provides the capability to interconnect the 7549 Gateway with external IP networks by means of up to two Gigabit Ethernet (GbE) interfaces. The GEI card interfaces are designed for use as network interfaces where network processor capabilities are needed, such as for the Per-Session Firewall function. The GEI cards plug into any of the four slots in the rear of the 7549 Gateway chassis on either side of the SST slots

The GEI card performs forwarding of VoIP packet traffic from the external network to the VS cards, and forwarding of VoIP packet traffic from the VS cards to the external network, while participating in the NAT learning function for firewall traversal. The GEI card can also perform IP-to-IP routing of traffic, including the associated Access Control List (ACL)filtering.Up to 4 cards per

Media Gateway, for IP(1:1)


ATM Interface Card

The ATM Interface (AI) card provides the capability to interconnect the 7549 Gateway with external ATM networks via OC-3c/STM-1c interfaces. Details of ATM transport are accommodated at the AI, allowing the Voice Server (VS) cards to process packetized voice in much the same manner regardless of what transport is used for the external network.The AI card performs forwarding of voice-application packet traffic from the external network ports to the VS cards,

Up to 4 cards per Media Gateway, for ATM

(1:1)


Voice Server (VS-8) Card

The Voice Server (VS-8) card mediates between channelized TDM voice streams and packet-based voice streams. The VS- 8 card has TDM interfaces to the SST and GbE interfaces to the PAC. It uses DSP resources to inter-work between those two interfaces.The VS-8 supports VoIP, UMTS and UMA and supports codecs, such as G.711, and AMR.

VS-8 cards can be inserted into any of the front slots of the 7549 Gateway chassis except for the dedicated PAC slots, so there can be up to 12 VS-8 cards configured per Gateway. The number of VS-8 cards required depends on the mix of codec types needed and the number of other cards in the 7549 Gateway

Up to 12 cards per Media Gateway, (N+1)


Echo Server Cards

The Echo Server (ES) card provides Hybrid Echo Cancellation (HEC) and TFO In-Path Equipment (IPE) for TDM call legs on the 7549 Gateway. All of these functions are directional, and the ES card can provide them in the appropriate direction for a TDM call leg. The ES card can be placed in any of the server slots in the front of the 7549 Gateway chassis.

Each ES card has 8K TDM timeslots, therefore up to 4,026 calls can be routed through it at any one time.



Network Interface Cards

The 7549 Gateway supports the following TDM network interface cards:• T1 Channelized Interface• E1 Channelized Interface• DS3 Channelized Interface• Quad OC-3/STM-1These cards can occupy any of the 12 network interface slots on the rear of the 7549 Gateway chassis

Up to 12 cards per Media Gateway, (N+1)/(1:1)


Network Interface Cards TDM NIC Sizing


Network Interface Cards - T1 or E1 Channelized Interface

Each 7549 Gateway unit can support up to 12 T1 or E1 cards, one of which is typically a redundant card. Each card supports up to 60 T1 or E1 ports, with up to 1,440 T1 DS0 channels or 1,860 E1 DS0 bearer channels per card. The T1 or E1 card has five 51-pin connectors on the faceplate, with each connector supporting 12 T1 or E1 ports.The T1 and E1 cards support 1:N unidirectional protection where N can be from 1 to 11 when only one card type is used



Network Interface Cards - DS3 Channelized Interface

The Channelized Interface (CI) Adapter card has two slots that can accommodate up to two DS3 CI SuperSlot cards. The CI Adapter card can reside in any of the 12 Network Interface slots on the rear of the 7549 Gateway chassis. Each DS3 CI SuperSlot card has three DS-3s for a total bandwidth of 2,016 DS0s. Configured with two SuperSlot cards, the CIAdapter card supports a capacity of up to 4,032 DS0s.



Network Interface Cards - Quad OC-3/STM-1

The Quad OC-3/STM-1 card has 4 OC-3/STM-1 ports on a single board which occupy any of the 12 Network Interface slots on the rear of the 7549 Gateway chassis. TheQuad OC-3/STM-1 card has 4 Small-Form Pluggable (SFP) optical modules.The Quad OC-3/STM-1 cards are 1+1 protected with unidirectional and bidirectional switching modes, as well as revertive and non-revertive switching supported. An OC- 3/STM-1 network interface (port) must be paired with a similar interface located on another card for protection.In case of a failure of any port, all the ports in the port group are switched over to their corresponding ports of the protecting port group.

Up to 12 cards per Media Gateway, (1:1)

7549 Media Gateway TDM Highway

The 7549 MGW provides 61 usable 1K DS0 TDM highways that are allocated in 1K increments. TDM interfaces, voice servers, and Echo servers utilize TDM highways. TDM interfaces use a fixed number of highways based upon the capacity of the card. Quad OC-3/STM-1 uses 8 highways, dual DS3 uses 4 highways, and T1/E1 uses 2 highways. Only active cards use highways. When a protection switch occurs, the highways assigned to the failed card are re-mapped to the protecting card. This design provides a nearly immediate protection switch without needing to remap each individual DS0 connection.Voice servers, echo servers utilize a provisioned number of TDM highways.This allows the network operator to optimally configure the server resources to match the anticipated codec mix for each specific application.
