FXS supplementary services description

FXS interfaces offer a set of supplementary services. Some of these services are locally terminated. Others, like conferencing, push the involved subscribers to an external service. These supplementary services are:

•Call hold (see page 411)

•Call waiting (see page 411)

•Call waiting reminder ring (CWRR) (see page 411)

•Drop passive call (held or waiting) (see page 412)

•Drop active call (connected call), accept passive call (held or waiting) (see page 412)

•Call toggle (see page 412)

•Call transfer (see page 412)

•Conferencing (see page 413)

•Call park (see page 413)

Note The local subscriber is always the one who executes the service.

The services call hold and call waiting allow the local subscriber to open or accept a second call. This is the condition for all the other services that are applied as soon as the local subscriber has two calls initiated to remote subscribers. That means the call hold service can only be applied as long as only one call is ongoing. All the above described service can be executed by a key pattern. Some of these services have permanent patterns for the others they can be configured by the user.

Note The flash pattern always has the short notation, '!'.
