Create a Channel-Group

If the desired encapsulated channel uses only selected time slots (not the entire PRI), then it is necessary to set
up a channel-group. To create a channel-group, set the PRI port's encapsulation to channelized. (See section
"Configuring PRI encapsulation".) On creating a new channel-group the channel-group configuration mode is
immediately entered. To remove an existing channel-group the 'no' form of the command has to be used.
Mode: port e1t1 <slot> <port>
Step
1 [name] (prt-e1t1)[slot/port]#[no] channel-
group group-name
Configuring Channel-Group Timeslots
The 'timeslots' command configures an arbitrary sequence of timeslots for use in data transmission. The syntax
of the command accepts comma-separated groups of timeslots. A group can be a single timeslot or a range of
timeslots. The channel-group timeslots do not have to be contiguous. The 'no' form of the command releases
all previously selected timeslots.
Example:
>timeslots 1,4,6
>timeslots 1,4-6
>timeslots 1-3,4-6
Mode: channel-group group-name
Step
1 [name] (ch-grp)[group-name]#[no]
timeslots 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. The number of selected timeslots in the Channel Group also defines the
data transmission rate of the hdlc protocol (n * 64kBit/s).
• q921: This encapsulation type can only be chosen if on the Channel Group only one timeslot is selected. It
is NOT possible to bind multiple timeslots to the q921 protocol.
• rbs: Robbed Bit Signaling encapsulation is only available for T1 ports.
On specifying this encapsulation type, all the timeslots specified in the Channel Group will be bound to the
PRI port configuration task list
Command
Selects three timeslots (1, 4 an 6)
Selects four timeslots (1, 4, 5 and 6)
Selects six timeslots (1, 2, 3, 4, 5 and 6)
Command
Purpose
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.
Purpose
Selects the timeslots to be used.
Default: no timeslots
