Bit Rate
Use this field to select the maximum transmission rate for DS1 circuit packs that support either
T-1 or E-1 service. For circuit packs that only support one of these services, the field is a
display-only field.
Note:
Once an add ds1 operation is complete (that is, the DS1 screen has been
Note:
submitted) you can't change the Bit Rate field with a change ds1 command.
Instead, execute a remove ds1 command. Then use the add ds1 command to
administer the circuit pack again. You'll have to re-enter all the information for the
circuit pack.
TN464C (and later release) circuit packs have an option switch that must be set
to match the entry in the Bit Rate field.

Channel Numbering
The ETSI and ISO QSIG specifications require that B-channels on an E1 be encoded as 1 to 30
in the Channel ID IE. Prior to the existence of this field, Avaya Communication Manager only
used this scheme for Country Protocols 2a (Australia) and 13a (Germany 1TR6). This field
appears when the Signaling Mode field is isdn-pri, the Bit Rate field is 2.048, the Connect
field is pbx, and the Interface field is peer-master or peer-slave.

Usage
Use for T-1 service.
Use for E-1 service.
Usage
If Avaya Communication Manager is connected via QSIG trunks to a
switch/server supporting the ETSI QSIG or ISO QSIG specifications, this
field must be sequential.
When the Signaling Mode field is isdn-pri and the Bit Rate field is
2.048, but the Channel Numbering field does not display because of the
setting of other fields, it is set internally to sequential for 2a (Australia)
and 13a (Germany).
