Processor - Avaya Nortel Communication Server 1000 Reference

NTDW60 Media Gateway Controller Card

Processor

The processor combines RISC processors, DSP resources, SDRAM controller, and UARTs.
The processor runs the application as well as providing tone and conference functions. It
interfaces to the rest of the system using Ethernet.
Ethernet ports
External connections
Of the six external Ethernet ports, three are reserved for ELAN subnet connections and three
for TLAN subnet connections. Two ELAN ports and two TLAN ports are accessed via RJ-45
connectors on the faceplate. The third ELAN and the third TLAN port are connected to the
backplane.
The two ports connected to the backplane are available if an Option 11C cabinet or a CS 1000M
Cabinet is used. The Option 11C cabinet requires a backplane adapter. The CS 1000M Cabinet
does not require a backplane adapter.
Internal connections
Four Ethernet ports provide internal connections: one to each of the expansion
daughterboards, and a TLAN subnet and an ELAN subnet connection to the processor.
Expansion daughterboards
Both expansion sites use the same PMC form factor and pin-out. However, one site is intended
for a VoIP daughterboard only and provides Ethernet and TDM connectivity. It is not accessible
from the faceplate and a PCI bus is not available. The other site provides a full PCI bus and
faceplate accessibility in addition to Ethernet and TDM.
