Adtran 1175407L2 Total Access 750/850 Total Access Quad FXO Card Expansion Module
The Foreign Exchange Office (FXO) and Foreign Exchange Subscriber (FXS) modules are used in the Total Access solutions to provide analog voice extension. The two units may be used in a back-to-back configuration. Here, the FXO interfaces to the central office switch, and the FXS interfaces to the customers telephone. Or, the more common configuration uses an FXS only, with the T1 interfacing directly to the CO switch (TR-08 mode). Four analog voice ports on the FXO/FXS access modules provide four individual connections to the switch or customer telephones. The units support standard loop start, ground start, and TR-08 signaling options. In addition to these signaling states, the FXS supports E&M to wink start, E&M to ground start, and several immediate start signaling states.
Provides four analog voice interfaces per module (up to 24 ports per chassis)
