Routing T1 carrier links to the MCR sites
A T1 carrier link terminates in a operating company demarcation point. From the operating
company demarcation point, T1 carrier links are routed to the MCR cards. The distance
between MCR and the CSU, the T1 line build-out, should not exceed 200 m (655 feet).
Therefore, MCR installations should be located within 200 m of their respective operating
company demarcation points and the first repeater boxes. The actual distance is DIP-switch
selectable on the LMIs and RMIs.
Note:
The NT7R87BA T1 CSU Cable Kit provided with the MCR equipment is used to connect the
LMIs and RMIs to operating company demarcation points (CSUs) at a distance of 32 feet
Mini-Carrier Remote Fundamentals
Note:
The DB-25F/DB-25F is not used.
This cable kit provides:
1 cable (32-foot, DB-9 female to DB-25 male)
1 adapter (null-modem, DB25 male to DB25 female)
2 labels (2 in. X 1.473 in., white, self-laminating)
At the local site, use this cable to connect the MMI terminal to the DB-9
male P5 connector of the NT5D85 LMI Multi I/O cable assembly.
At the remote site, use this cable to connect the MMI terminal to the
DB-9 male P5 connector of the LMI Multi-I/O cable assembly
(NT5D85).
This cable kit provides:
1 cable (32-foot, RJ48 to RJ48)
1 cable (sub-assembly, T1/CSU RJ48 to RJ48)
1 adapter (CPE to network, male DB15 to RJ48, NT7R93AA)
1 adapter (CPE to network, female DB15 to RJ48, NT7R93BA)
1 adapter (CPE to CPE, female DB15 to RJ48, NT7R93CA)
1 label (2 in. X 1.473 in., white, self-laminating)
At the local site, the NT7R93BA adapter is used to connect to P2 and/
or P3 (depending on the number of T1s in use) of the NT5D85 LMI
Multi-I/O Cable Assembly to the CSU/DSU. NT7R93AA may be
required for this connection, depending on equipment-type.
At the remote site, the NT7R93BA adapter is used to connect to P2
and/or P3 (depending on the number of T1s in use) of the NT5D85
LMI Multi-I/O Cable Assembly to the CSU/DSU. NT7R93AA may be
required for this connection, depending on equipment-type.
Note:
The NT7R93CA adapter is only necessary for connection with the
NT7R93BA adapter in a direct-cable connection that does not use
T1, thus not using a CSU/DSU.
