Table 14 shows the settings for RMI DIP switch 3, positions 1-3, to set
various T1 Line Build-out lengths
Defaults are SW3, position 1 ON and all others OFF, which corresponds to a
T1 Line Build-Out of shortest length and ESF framing mode. The MMI and
SDI connections run at 9600 baud and default to N,8,1.
Note: Both T1s are set to the same cable distance and framing mode.
Connecting T1 carrier links to the MCR
In an MCR system, the T1 carrier links are routed to the cabinet and
connected to the RMI through the RMI Multi-I/O Cable Assembly (NT5D87)
from the telco demarcation point.
Note: Before connecting the T1 carrier link to the system, the
connection between the telco demarcation point such as CSU, is
completed using the NT7R87BA T1 CSU Cable Kit.
Using the MMI command
SET SPAN (S S),
program the number of T1
channels supplied by your service provider. Refer to “SET SPAN (S S)” on
page 98 for a detailed description of this process.
