Trunk Assignments for Double-Cabinet Systems
• When T1 is used in a double-cabinet system, the number of T1 channels
that can be assigned in each cabinet depends on the master/slave
designation.
The following table shows the maximum number of T1 channels that can
be assigned in two-cabinet systems.
Table 4-12. Maximum T1 assignments for two-cabinet systems
• Two-cabinet systems use the same trunk numbering scheme as single-
cabinet systems. Analog trunks are numbered from “1” upward; T1 trunk
channels are numbered downward from the highest channel used.
