1032 NTDW60 Media Gateway Controller CardProcessor The processor combines RISC processors, DSP resources, SDRAMcontroller, and UARTs. The processor runs the application as well asproviding tone and conference functions. It interfaces to the rest of thesystem using Ethernet.Ethernet portsExternal connectionsOf the six external Ethernet ports, three are reserved for ELAN subnetconnections and three for TLAN subnet connections. Two ELAN ports andtwo TLAN ports are accessed via RJ-45 connectors on the faceplate. Thethird ELAN and the third TLAN port are connected to the backplane.The two ports connected to the backplane are available if an Option 11Ccabinet or a CS 1000M Cabinet is used. The Option 11C cabinet requires abackplane adapter. The CS 1000M Cabinet does not require a backplaneadapter.Internal connectionsFour Ethernet ports provide internal connections: one to each of theexpansion daughterboards, and a TLAN subnet and an ELAN subnetconnection to the processor.Expansion daughterboardsBoth expansion sites use the same PMC form factor and pin-out. However,one site is intended for a VoIP daughterboard only and provides Ethernetand TDM connectivity. It is not accessible from the faceplate and a PCIbus is not available. The other site provides a full PCI bus and faceplateaccessibility in addition to Ethernet and TDM.Backplane interfaceThe FPGA features include:• Serial data interface port• Time slot interchanger (TSIC)• SSD X12/A10 signaling interface• CE-Mux bus interface• CardLan interface• DS30x interface• TDM bus for tones and conference• System clock generation and system clock referenceNortel Communication Server 1000Circuit Card ReferenceNN43001-311 01.04 StandardRelease 5.0 23 May 2008Copyright © 2003-2008, Nortel Networks.
