Component
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 1:
equipment is used to connect the LMIs and RMIs to operating company
demarcation points (CSUs) at a distance of 32 feet (9.75 m). Install this
cable kit, if applicable, between the CSU and the LMI at the local site
and the RMI at the remote site as a preinstallation procedure.
Note 2:
the public switched network or other exposed plant networks. Always
connect this product to such networks through a certified (by local,
regional, or national safety agency and telecommunications authority),
isolating type network terminating device (such as CSU, DSU, NT1, or
NCTE) that provides overvoltage protection.
Route twisted-pair wires for T1 carrier links from the operating company
demarcation point to the MCR equipment. Use standard cable routing
procedures to prevent cable exposure to possible damage from contact
with machine and human traffic. Terminate the twisted-pair wires with an
8-pin modular plug.
Description
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.
The NT7R87BA T1 CSU Cable Kit provided with the MCR
Mini-Carrier Remote is not intended for direct connection to
