Configuring ISDN PRI B Channels
ISDN Primary Rate Interface (PRI) software eliminates the need for an external
ISDN terminal adapter (TA) when attaching a Nortel Networks BLN or BCN
router to an ISDN network. The ISDN PRI software interface connects directly to
an ISDN switched service network through an MCT1 or MCE1 link module.
The Nortel Networks ISDN PRI software interface complies with the North
American and European ISDN PRI standards. The North American standard
provides 23 B channels of 64 Kb/s each and one 64 Kb/s D channel. The European
standard provides 30 B channels and one D channel.
Using the BCC
To configure ISDN PRI B channels, complete the following tasks.
1.
To configure PRI, navigate to the mce1 or mct1 prompt (for example,
stack
;
mce1/1/2/1
) and type:
mce1/1/2/1#
pri
2.
To assign a timeslot to the B channel, type:
pri/1/2/1#
channels 1
You can assign a timeslot to all channels or from 1 to 23 channels.
To assign multiple timeslots to a B channel, type:
pri/1/2/1#
channels {1 2 3 4}
3.
To set the MTU size, type:
pri/1/2/1#
mtu 100
You can set the MTU size from 3 to 4608 bytes. The default is 1600 bytes.
