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/8TRK2 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.
