4.3 Timeslot Allocation with a T1-S and the Secondary T1 Unit (3608-80)
When the T1-S is used in conjunction with a secondary T1 unit (ST1U), 48 timeslots are available for allocation
(24 for the T1-S and 24 for the ST1U). The timeslot allocation process is similar to that used for the T1-S only.
See the section on timeslot allocation in the Secondary T1 documentation for more information.

5.1 Installing the Unit
The T1-S installs in the primary slot of the 360-80. A Secondary T1 unit may be mounted in the secondary slot in
some applications. See Figure 9 for a sample of the shelf layout.
