16 • PRI port configuration

 

 

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

Command

Purpose

 

 

 

1

[name] (prt-e1t1)[slot/port]#[no] channel-

Enters the channel-group configuration mode of

 

group group-name

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.

 

 

 

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

Purpose

 

 

 

1

[name] (ch-grp)[group-name]#[no]

Selects the timeslots to be used.

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. 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
