1032 NTDW60 Media GatewayController 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.
Backplane interface
The 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 reference
