Packet data transmission
553-3011-311
Standard 7.0
Chapter 7 — Acceptance testing
You may wish to repeat this test on several terminals including both
intelligent and dumb terminals.
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 external packet
handler at 64 kbps over dedicated ISDN PRI B-channels. The external packet
handler processes the data and distributes it to local terminals for local calls
or over the packet data network for remote calls.
D-channel packet data terminals communicate at the baud rate of up to
9.6 kbps. The packet data is multiplexed onto a 64 kbps B
linked through a dedicated ISDN PRI B-channel with the external packet
handler. The packet handler processes the data and distributes it to local
terminals for local calls or over the packet data network for remote calls.
Note: To perform packet data transmission verification, the system must
be connected to a packet handler and packet data transmission functions
must be selected when configuring the B-channel and D-channel
transmission characteristics using Service Change BRI Program LD 27.
To specify this feature, refer to the ISDN BRI line and packet data
implementation chapter of this guide in MISP configuration procedures.
In addition to configuring the MISP and the DSL using Service Change BRI
Program LD 27, you must make sure that:
— the ISDN PRI loop to carry packet data has been configured using
Configuration Record Program LD 17
— the packet handler route is specified by using Trunk Route
Administration Program LD 16
— a PRI channel for the packet handler route has been configured using
Trunk Administration Program LD 14
Refer to the ISDN BRI line and packet data implementation chapter in this
guide for a detailed description of how to configure relevant ISDN BRI
packet data transmission parameters using LD 17, LD 16, and LD 14
programs.
