Network module (NT8D35)
The NT8D35 Network module houses the circuit cards which are used to
provide the digital multiplexed network loops of the switch.mg system,
along with the control and signalling cards
rquired
to interface the
switching function with the CPU. The NTSD35 Network Module is used in
Meridian 1 system option 71 only. The NT8D35 module also supports
Digital Trunk Interface (DTI) and/or Primary Rate Interface
@‘RI)
cards.
For configuration flexibility the NT8D35 Network module is available with
an AC power option or a DC power option. These power supplies provide
the voltages to operate the circuit cards located in the modules.
The NT8D35 Network module houses up to eight QPC414 (ENET) cards or
four NT8DO4AA SuperLoop Network cards, or any combination for a total
of 16 network loops per module. In a typical configuration, 14 voice/data
loops are available when one NT8D17 Conference/Tone and Digit Switch
card is configured in the module. Two NT8D35 modules are required to
make a full network group of 32 loops. A maximum of 10 NT8D35
Modules (5 network groups) may be configured.
