BRI port configuration task list 208
SmartWare Software Configuration Guide 17 • BRI port configuration
Configuring channel-group timeslots
The ‘timeslots’ command configures the timeslot for use in data transmission. On a BRI port, only the B-
Channels can be selected (0 or 1).
Mode: channel-group <group-name>
Configuring channel-group encapsulation
The encapsulation command prepares the Channel Group for a specific application protocol. After the right
encapsulation type has been set, the configuration mode command for the selected protocol can be executed
for protocol specific configuration.
• hdlc: Enables HDLC Framing on the selected Channel Group. After encapsulation hdlc has been specified,
the hdlc configuration mode can be entered to configure hdlc specific parameters and to define the link
layer protocol must run over hdlc.
Mode: channel-group <group-name>
Entering HDLC configuration mode
The hdlc configuration mode can be entered from the ‘channel-group’ configuration mode if the encapsulation
is set to ‘hdlc’ and a timeslot has been specified. If the hdlc configuration mode is not accessible, it may be due
to an invalid or incomplete configuration. In this case, an error message will be issued.
Mode: channel-group <group-name>
Configuring HDLC encapsulation
The hdlc encapsulation command specifies what kinds of upper layer data are contained in the hdlc frames.
Currently, only PPP can be chosen. For more details about PPP configuration, see Chapter 30, “PPP configu-
ration” on page 313. Also, see “Example 3: Multi-Link PPP over two B-Channels” on page 211.
