2.3 SWITCH MODULES (ELEMENTS)

The Switch is constructed of different modules that interface from the Switch to external devices. The modules are:

•Channel Interface Module (CIM), to the Multi-Net or LTR System.

•Conventional Channel Module (CCM), to a Conventional Channel, channel side.

•Dispatch Interface Module (DIM), to the Dispatch Consoles.

•Telephone Interface Module (TIM), to the PSTN or a PABX.

•System Network Module (SNM), to other SNM, Switches.

•Network Interface Module (NetNIM), to the Call Processor.

•Dispatch Channel Module (DCM), to the Conven- tional Channel, network side.

•Voter Diagnostics Module (VDM), to the Voter system.

•Power Termination Module (PTM), provides fusing of power and termination for a shelf.

•Intelligent Dispatch Module (IDM), to the Tracer Series Dispatch Consoles.

•Logging Encoder Module (LEM), interface to a logging recorder.

•Multi-Net Acquisition Module (MAM), interface from the Switch to the VR-CM50 CRT Consoles for Tone Paging.

•Multi-Net Console Module (MCM), to VRCM-50 CRT Consoles.

•Conventional Patch Module (CPM), to dynamically patch a single conventional channel to a single trunked group.

•Wide Area Module (WAM), to other WAMs, Switches.
