3.6 CONNECTING POWER FAIL TRANSFER

The OfficeServ 7100 offers a Power Fail Transfer feature for analog single line
telephones that are connected to port 1 (pins 1 & 2) on the 8SLI or port 1 (pins 7 & 8)
on the 16MWSLI cards.
In case the OfficeServ 7100 loses power from its AC source, and no battery backup is
available, this feature is automatically activated. The SLT connected to Port 1 of the SLI
will get C.O. dial tone (direct C.O. line access) activated by an internal relay. For this
feature to work, the SLI ports must be wired as shown in Figure 3.29 Pin 4 (TIP) and Pin
5 (Ring) from a port on the 8TRK card (or a port of the 4TRM module) must be
connected to Pin 1 (TIP) and Pin 2 (RING) on port 1 (pins 1 & 2) of an 8SLI card or port
1 (pins 7 & 8) of 16MWSLI card.
