2.2 ELEMENTS OF THE SWITCH
The Switch is a rack of modules. The rack may
contain the following modules: (Table 2-1).
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.
