Bit Rate
Note:
TN464C and later release circuit packs have an option switch that must be set to match this
Bit Rate value.
Valid Entry Usage
1.544 The maximum transmission rate for DS1 circuit packs that support T-1
service.
2.048 The maximum transmission rate for DS1 circuit packs that support E-1
service.
Signaling Mode
Selects the signaling method used for the DS1 link. This mode must match the method used
by the network services provider.
Valid Entry Usage
CAS Channel Associated Signaling. Out-of band signaling with E1 service.
This setting yields 30 64-kbps B-channels for voice or data transmission.
Channel 0 is used for framing while channel 16 carries signaling. Used
for Enterprise Mobility User (EMU)/EC500 administration.
robbed-bit In-band signaling with T1 service. This setting yields 24 56-kbps B-
channels for voice transmission.
isdn-pri Either T1 or E1 ISDN service. This setting supports both Facility
Associated Signaling and Non-Facility Associated Signaling.
isdn-ext Either T1 or E1 ISDN service. This setting supports only Non-Facility
Associated Signaling.
Note:
NFAS is primarily a feature for ISDN-T1 connections offered by service
providers in North America and Hong Kong. However, it can also be
used on private-network connections, and in that context it is possible
to set up NFAS using ISDN-E1 interfaces.
common-chan Out-of-band signaling with T1 service. This setting yields 23 64-kbps B-
channels for voice or data transmission. Channel 24 is used for
signaling.
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). Available
only with ISDN-PRI signaling on a private network. The interface must be peer master or peer
slave.
