Installing a
Tl
in a Single Cabinet
Chapter 4. Trunks and Lines
The following instructions explain how to install a
Tl
in a single-cabinet
system. These instructions also apply when a
Tl
is installed in only the
master cabinet of a two cabinet system.
If only one
Tl
is installed in a two-cabinet system, it must be installed in the
cabinet specified in Table 4-8 on page
4-
13.
Note: The Tl Interface cannot be used for systems consisting of a DBS 72
connected to a DBS 40.

Pins 2 and 3 are strapped. (See Figure 4-5.)
When Pins 2 and 3 are strapped, the Sync Unit synchronizes the DBS
Tl
card with the signaling provided by the public network.
