tion “Configuring T1/E1 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>
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 Selects three timeslots (1, 4 an 6)
>timeslots 1,4-6 Selects four timeslots (1, 4, 5 and 6)
>timeslots 1-3,4-6 Selects six timeslots (1, 2, 3, 4, 5 and 6)
Mode: channel-group group-name
Configuring Channel-Group Encapsulation
In the channel-group configuration mode only the encapsulation type ‘hdlc’ is available. For more details see ,
“Configuring T1/E1 encapsulation” on page 62.
Mode: channel-group group-name
Entering HDLC Configuration Mode
The hdlc configuration mode can be entered either from the “port T1/E1” configuration mode or from the
“channel-group” configuration mode. If you cannot enter the hdlc mode, it may be due to an invalid or incom-
plete configuration, and an error message will be issued. In “port T1/E1” configuration mode, you only need
to set the encapsulation for ‘hdlc’ in order to enter the hdlc configuration mode. In “channel-group” configu-
