Chapter 1 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.
