configured, the recommended initial setting is 1000 ms
.
Possible settings are 250 , 500 , 750 , 1000 , and
2000 ms.
Use forward-disconnect battery to specify the behavior of the battery when the remote equipment
ends the call. Possible settings are remove and reverse . Selecting remove configures the FXS to
remove battery from the circuit when the remote equipment ends the call. Selecting reverse configures
the FXS to reverse battery polarity on the circuit when the remote equipment ends the call. By default,
forward-disconnect battery is disabled. Setting forward-disconnect battery is only necessary when
em-conversion is configured and a forward-disconnect delay specified. If configured, the
recommended initial setting is forward-disconnect battery remove .
TDM Groups
An FXS port can only connect to a single DS0, so there are no TDM groups for FXS ports. FXS ports
are assigned to DS0s using the
cross-connect command discussed in Connecting the Interfaces on
page 21.
Activation
The user may activate each port individually, or if the range command is used many ports can be
activated simultaneously. To activate each port one at a time, first enter interface fxs 2/1 from the
Global configuration mode. Type no shutdown . Then type interface fxs 2/2 to move to the next port
and repeat through interface fxs 6/8 .
To activate all the ports with the range command, type interface range fxs 2/1-8 , fxs 3/1-8 , fxs 4/1-8 ,
fxs 5/1-8 , fxs 6/1-8 and then type no shutdown .
See Verifying Your Configuration Using Show Commands on page 36 for more information on the
status of each FXS port.
Voice Ports (FXO)
From the prompt, IAD# , enter configure terminal . All interfaces will be configured from within the
configure terminal mode. Enter interface fxo 7/1 to configure the first FXO port on the access module
in slot 7.
The user may configure each port one at a time or use the
range
command to set a group of ports at the
same time. To use the range command, type interface range fxo s lot x/port a-b, fxo slot y/port a-b
where slot x and y are slots with FXO cards installed and port a-b specifies the range of ports to be
configured. For example, to configure FXO slot 3, ports 1-8 and FXO slot 5, ports 1-4, from the Global
configuration prompt, type
interface range fxo 3/1-8, fxo 5/1-4 . Then type the desired command to
configure all 12 of the specified ports identically.
Making configuration changes while a port is active will cause the call to drop.
