FXS Voice Card
Overview
Overview
The FXS Voice Service card provides high-density provisioning of cost-effective
telephone services. Eight Foreign Exchange Station (FXS) telephone line channels can
be deployed on each FXS Voice Service card. These cards can be inserted into any card
slot of the six-slot Compact T1. This allows the provisioning of up to 48 FXS lines in
a single chassis and up to 96 lines in two side-by-side units occupying just two rack
units of space.
A unique range of software-controlled signaling capabilities connects virtually any
type of 2-wire battery-feed telephone line service. FXS loop start or ground start
interfaces provide either outside (external) phone lines or on-premises (internal)
business line services. Supported features include caller ID, calling party disconnect,
distinctive ringing, three-way calling, and E&M signaling conversion. Automatic
impedance balancing provides echo-free service connections for a wide range of
customer equipment and line conditions. V.90 transmission ensures optimal dial-up
modern performance.
As a component of the Compact T1 platform, the FXS service card has several local
and remote management options available through the Controller. The card can be
locally configured and managed using the front-panel DIP switches or the Command
Line Interface (CLI). Front-panel LEDs quickly communicate call progress and
channel status.
