BRI port configuration task list 207
SmartWare Software Configuration Guide 17 • BRI port configuration
Configuring BRI Power-Feed
Enables the application of power on the BRI port to provide power to ISDN terminals. This command applies
only if the port is clock master (network side). It is only available on products with an internal, configurable
ISDN power supply.
Mode: port bri <slot> <port>
Configuring BRI encapsulation
The BRI encapsulation command prepares the port for a specific application protocol. After the right encapsu-
lation type has been set, the configuration mode command for the selected protocol can be executed for proto-
col specific configuration.
• q921: This encapsulation type automatically binds the signaling timeslot of the selected port to the ISDN
Layer 2 protocol. For the BRI port this is the 16kbit/s D-channel. If in the q921 configuration mode q931
is specified as next encapsulation, the control of the two remaining timeslots (B-channels) is given to the
ISDN Layer 3 protocol. For more information please consult Chapter 19, “ISDN configuration” on
page 217.
• channelized: This special encapsulation type pushed the port in a mode where it is possible to setup an
application for a user-defined timeslot. Normally, all timeslots of a port are under full control of the appli-
cation specified with the encapsulation command. In ‘channelized’ mode, and application uses only the
specified timeslot. If the encapsulation is set to ‘channelized’, use the channel-group command to create a
new Channel Group and to enter its configuration mode. The requested can then be selected with the
Channel Group’s encapsulation command.
Mode: port bri <slot> <port>
Creating a channel group
If the desired encapsulated channel uses only a selected time slot (not the entire BRI), then it is necessary to set
up a channel-group. To create a channel-group, set the BRI port’s encapsulation to channelized. (See s“Config-
uring BRI encapsulation”.) On creating a new channel-group the channel-group configuration mode is imme-
diately entered. To remove an existing channel-group, the ‘no’ form of the command must be used.
Mode: port bri <slot> <port>
Step Command Purpose
1 [name] (prt-bri)[slot/port]#[no] power-
feed
Enables/Disables power-feed on the selected port.
Default: disabled
Step Command Purpose
1 [name] (prt-bri)[slot/port]#[no] encapsu-
lation { channelized | q921}
Specifies the encapsulation type of the BRI port.
Default: q921
Step Command Purpose
1 [name] (prt-bri)[slot/port]#[no] channel
group <group-name>
Enters the channel-group configuration mode of
group-name. If the group does not yet exist a new
one will be created. The ‘no’ form of the command
removes an existing channel-group.
