Introduction

This chapter provides an overview of FXS interfaces, and the tasks involved in their configuration. This chapter
does not explain the basic configuration steps equal to all CS interfaces. Information about basic interface con-
figuration can be found in the general chapter about CS interface configuration (see chapter 27,
configuration" on page 322).
An FXS interface represents the connection of an analog FXS port signaling to the call control of SmartWare.
It encapsulates the signaling of the exchange side of a POTS line, allows incoming and outgoing calls on this
line, controls the line events, tones and datapath, and provides a set of supplementary services.
There is a one-to-one relation between the port and the interface: Only one port can bind to an existing inter-
face, and there must be a port that binds to the interface for the interface to become functional (see

FXS supplementary services description

FXS interfaces offer a set of supplementary services. These services are locally terminated (i.e. no other device is
involved in providing the services), and they can be enabled/disabled separately. The services are:
•

Call holding

•

Call waiting

• Additional call offering
Other supplementary services can be configured using general context CS functionality.

Call holding

There is the possibility to have two open calls on one POTS terminal: One of the two calls being active, the
other passive or on hold.
Procedure: To toggle active and passive call, press flash-hook, followed by the 2 key

Call waiting

When the analog line is busy, a second incoming call on the same interface announces itself using a special
tone, the waiting tone. The user can then decide whether to accept the new call (put the current on hold or
drop it), or to reject it (keep the current call).
