Channel Numbering
The ETSI and ISO QSIG specifications require that B-channels on an E1 be encoded as 1-30 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.
Connect
In order to control communications at layers 2 and 3 of the ISDN-PRI protocol, use this field to specify
what is on the far end of this DS1 link. This field only appears when the
Signaling Mode
field is
isdn-pri.
Valid entries
Usage
timeslot
sequential
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).
Valid entries
Usage
pbx
Enter pbx if this DS1 link is connected to another switch in a private
network. If pbx is entered, the
Interface
field appears.
line-side
Enter line-side when Communication Manager is acting as the
network side of an ISDN-PRI interface. Use line-side to connect to
Roll About Video equipment.
network Enter
network when the DS1 link connects Communication
Manager to a central office or any other public network switch.
host
Enter host when the DS1 link connects Communication Manager to
a computer.
