Testing ISDN BRI functions
Packet data transmission
A packet data call can be established between two data terminals over a B-channel or a D-
channel.
B-channel packet data terminals communicate with the packet handler at 64 kbps over
dedicated B-channels. The packet handler may be an external packet handler, the DPN-100,
or the integrated MPH. The packet handlers processes and distributes the data to local
terminals for local calls or over the packet data network for remote calls.
D-channel packet data terminals communicate at a baud rate of up to 9.6 kbps. The packet
data is multiplexed onto a 64 kbps BD that is linked with the external packet handler through
a dedicated ISDN PRI B-channel, or, in the case of the MPH, through a dedicated
connection.
Note:
To perform packet data transmission verification, the system must be connected to a
DPN-100, or configured with MPH. Also, packet data transmission functions must be
selected when configuring the B-channel and D-channel transmission characteristics. Use
LD 27 to specify the packet data transmission functions. See "MISP configuration
procedures" in Avaya ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).
In addition to configuring the MISP and the DSL in LD 27, ensure the following:
• the ISDN PRI loop carrying packet data was configured in LD 17
• the packet handler route was specified in LD 16
• an ISDN PRI channel for the packet handler route was configured using LD 14
See Avaya ISDN Basic Rate Interface Feature Fundamentals (NN43001-580) for a detailed
description of how to configure relevant ISDN BRI packet data transmission parameters in LD
17, LD 16, and LD 14.
