Secondary Timing

The secondary interface is the source of timing. The TSU 120

uses the clock derived by the secondary interface for transmis-

sion timing and the receive signal timing. See Figure 5-6.

Either a DSX-1 Option Module or a Drop and Insert Option

Module must be installed in the TSU 120 for this mode to func-

tion.
