FXS supplementary services description 411
SmartWare Software Configuration Guide 35 • FXS interface configuration
The command to change the key patterns is available in the interface fxs configuration mode. If the patterns
start with the same key sequence, they should also have the same length. The key parser is of type best match-
ing so it executes the service of the first pattern that represents a full match.
Mode: Interface FXS
Call hold
This service is used to set the remote subscriber on hold and offers the possibility to set up a second call to the
local subscriber. Call hold is activated by flash and then the local subscriber will hear the dial tone and the
remote subscriber will be set on hold. For the action on the remote side, the far end device is responsible. It can
play the hold tone, hold music or an inband message. In this state, the held subscriber can be retrieved by
touching flash. If the local subscriber hears the dial tone and doesn't start dialing, the call waiting tone will play
after a timeout of five seconds. To retrieve the held subscriber in this state, touch flash. It is possible to disable
this service by executing the command no additional-call-offering on the fxs interface.
Mode: Interface FXS
Call waiting
The call waiting service doesn't need a special pattern. The user can use either drop passive call to reject the
incoming call, can use call toggle to hold the active call and to accept the incoming call or can use drop active
call to disconnect the current one and to switch to the incoming call. Call waiting can be explicitly disabled by
executing the no call-waiting command on the fxs interface.
The user of the device connected to the FXS port can be given the option to activate/deactivate call waiting by
means of a special digit sequence touched on the keypad of his device (see section, “Configuring the precall ser-
vice tables” on page 388). The configuration in the fxs interface is administrative what means if call waiting is
disabled here, the user cannot activate it anymore.
Mode: Interface FXS
