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>

Step	Command	Purpose
1	[name] (ch-grp)[group-name]#[no]	Selects the timeslot to be used.
	timeslots <timeslots>	Default: no timeslots

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>

Step	Command	Purpose
1	[name] (ch-grp)[group-name]#[no] encap-	Specifies the encapsulation type of the channel-
	sulation {hdlc}	group.
		Default: no encapsulation

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>

Step	Command	Purpose
1	[name] (ch-grp)[group-name]#hdlc	Enters the hdlc configuration mode.

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.

Mode: channel-group <group-name>

Step	Command	Purpose
1	[name] (hdlc)#[no] encapsulation {ppp}	Specifies the encapsulation type of hdlc.
		Default: no encapsulation
