Meridian Cabinet Trunk Module-ISDN

The Meridian Cabinet Trunk Module-ISDN (MCTM-I) contains up to two
duplicated Common Peripheral Controllers that can be configured as LTC-Is,
LGC-Is, DTC-Is, LTGs, LGCs or DTCs.
Line Trunk Controller-ISDN
The LTC-I is a peripheral module that is a combination of the LGC and
the DTC and provides all the services offered by both. The LTC-I is wired
for any combination of LTC-I, DTC-I, or LGC-I supporting up to eight Line
Concentrating Modules (LCMs) or Digital Line Modules (DLMs) requiring up
to 20 DS-30A trunk ports and 16 DS-30 line ports.
The LTC-I and DTC-I can support DS-1 ports. The DS-1 ports for each
LTC-I are fully wired to filtered connectors in the rear bulkhead for use as
digital trunks, to connect remote modules, or both.
Up to eight LCMs or DLMs can be configured for each LTC-I. Each LCM or
DLM has a dedicated connector on the rear bulkhead, which is prewired for
six DS-30A links, simplifying the external cabling to the MCLM or MCDM.
Inside the cabinet, the wiring permits on-site configuration for two to six links
for each LCM or DLM. Cables providing 16 network DS-30 links to each
LTC-I are connected to the LTC-I as needed, on site.
