Introduction
QUAD FXS VOICE MODULE OVERVIEW
The Quad FXS Voice Module (see Figure 1-1) is for use in the Total Access
750/850/1500 (TA 750/850/1500) platforms to provide analog voice exten-
sion. The Quad FXS resides in the TA chassis that is next to or close to the
customer’s telephone and is usually located on the customer’s premises.
This unit can be used in conjunction with the TA 750/850/1500 FXO Voice
Module, which resides in the TA 750/850/1500 that is located next to the
Central Office switch.

If TR-08 signaling format is not readily available at the CO switch, both FXO
and FXS access modules can be used for deployment. The TA 850 at the CO
will combine a number of analog lines and then multiplex them for T1 trans-
mission to the TA 850 at the customer premise. If using the TR-08 signaling
option, the Quad FXS can communicate directly with the Central Office
Switch without needing a Quad FXO.
