point. The local demarcation point is defined as the end of the NT5D85 (or
NT7R66AA, or NT7R66BA, or NT7R86AA, or NT7R87AA).
Remote hardware requirements
The hardware installed at the remote site is divided into three categories.
The first category relates to the unique MCR hardware. The second
relates to the cabinet and associated hardware. The third relates to the
IPE cards installed in the remote cabinet.
MCR-unique hardware
Each remote site requires an RMI card placed in the core processor card
slot of the standard cabinet. In addition to the card, an interface cable is
required.
RMI Multi-I/O cable assembly (NT5D87)
Each RMI must be equipped with a two-foot-long RMI Multi-I/O cable
assembly (NT5D87) interface cable that connects to the 50 pin Amphenol
connectors located on the lower section of the cabinet backplane.
The opposite end of each RMI Multi-I/O cable assembly (NT5D87)
provides connections for the following items:
•
first T1 carrier link
•
second T1 carrier link
•
external alarm
•
Man-Machine Interface (MMI)
•
Serial Data Interface (SDI)
If required by the customer, the following optional cables can be connected
to the RMI Multi-I/O cable assembly (NT5D87):
NT7R87BA CSU Cable Kit (32 ft).
NT7R66BA MMI Cable Kit (32ft).
NT7R86AA Auxiliary Alarm Cable (25 ft).
