In this case the command line prompt is telling us that the remote

command mode is active over the local KBU's channel A (1) and that we

are currently at the command prompt for channel 1 on the remote KBU

64.

A prompt of A2> indicates the ISDN link is on channel A(1) of the local,

and you are prompting channel 2 of the remote KBU.

A prompt of B1> indicates the ISDN link is on channel B (2) of the local,

and you are prompting channel 1 of the remote.

A prompt of B2> indicates the ISDN link is on channel B (2) of the local,

and you are prompting channel 2 of the remote.

All commands that you enter at one of these command line prompts, will

be actioned by the remote KBU 64, just as if you were directly connected

to it's COMMAND port.

All configuration commands of the KBU 64 are available to you.

Note: Take extreme care when using Talkwire to change the

configuration of a remote unit, it is possible to alter a

parameters which will result in locking yourself out of the unit,

making further Talkwire connections impossible until the unit is

re-configured from a local terminal!

7.8 Using Talkwire During a Backup

When the KBU 64 initiates a backup call, Talkwire can be set to ON or

OFF, although it would normally be set to ON. When backup is initiated

and Talkwire is set to OFF, the originating KBU 64 calls the remote KBU

64 over the ISDN line. On receiving the call, the remote unit answers

and, after a predetermined delay, switches the user data from the

Kilostream link to the ISDN line. The originating end will also switch

(after a predetermined time), thus providing a backup data path over the

ISDN.

The called KBU64 must have CONNECT set to AUTO, in order to

connect the USER ports to ISDN with TALKWIRE set OFF. If Talkwire is

set to ON, and a backup is initiated, the originating KBU 64 calls the

remote KBU 64 over the ISDN line. On receiving the call, the remote

unit detects a Talkwire sequence on the line, when it replies by sending a

Talkwire sequence back to the originating KBU 64.
