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 33,
configuration" on page 379).
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 FXS 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 interface, and there must be
a port that binds to the interface for the interface to become functional (see
FXS interface configuration task list
This section describes the configuration tasks for FXS interfaces. There is no mandatory configuration for basic
FXS operation.

• Using an alternate PSTN profile (optional) (see
• Configuring caller-id presentation (optional) (see
• Configuring flash hook processing (optional) (see
Configuring a subscriber number (recommended)
Contrary to ISDN, where each terminal knows its own subscriber number (MSN), an analog device doesn't
have this capability. If such a device is connected to an FXS port and makes an outgoing call (goes off hook and
dials), the dialed digits form the called party number. But there is no calling party information available from
the FXS protocol. To insert calling party information and make it available to other protocols over which the
call may be transported, a subscriber number must be configured on the interface.
Note
The configured subscriber number does not affect the routing of incoming
calls on the interface.
