Installing a T1 in a Single Cabinet
The following instructions explain how to install a T1 in a single-cabinet
system. These instructions also apply when a T1 is installed in only the
master cabinet of a two cabinet system.
If only one T1 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 T1 Interface cannot be used for systems consisting of a DBS 72
connected to a DBS 40.
1. Check connector 4 (CN4) on the Sync Unit (VB-43563). Make sure that
Pins 2 and 3 are strapped. (See Figure 4-5.)
When Pins 2 and 3 are strapped, the Sync Unit synchronizes the DBS T1
card with the signaling provided by the public network.
