FXO Telephony Trunk Interface Module

XR0025

The FXO telephony trunk interface module (P/N XR0025) is used to connect analog telephone trunks (and in some cases legacy PBX) to the Asterisk PBX.

Each FXO telephony trunk interface module has 8 ports for 8 analog telephone trunks. The Astribank unit is cable of carrying up to 4 FXO modules supporting up to 32 analog trunks. FXO also supports fax, however, when using FXO and ISDN (BRI, PRI or R2 digital telephony) on the same system, the fax line must be connected to ISDN.
