Talkwire Operation
80-10200000-01
5–3
1: DIALLING xxxxxxx
1: RINGING
1: ONLINE
1: TALKWIRE ACTIVE (V2+)
During this dialling sequence, the terminal operator of the remote
SBU128 will be notified of the incoming call.
Note that the calling line ISDN number will only be presented if the
network is providing the CLI. An unsuccessful Talkwire call will be
identified by a screen message of:
1: TALKWIRE TIMEOUT
This is displayed after the time set within the Talkwire Delay Timer has
elapsed. Talkwire continues to be operative, trying to establish the
connection. If the link becomes useable at any time, for any reason, a
Talkwire connection will be established at that time.
5.4 Using Talkwire for DLC Testing
The Talkwire facility may also be used to monitor the state of a DLC,
after the data path has backed up to the ISDN line.
With Talkwire enabled at both ends of the link, when the backup call is
initiated (either automatically or manually) a Talkwire link will be made.
You have already seen that a Talkwire link can only be operational on
the opposite path to that used by the data traffic. When the data is now
switched to the ISDN line, the Talkwire connection switches to the DLC,
and continually transmits minimal data to try to establish a link to the
remote unit.
When the DLC is repaired or restored, Talkwire is then able to make a
satisfactory connection, indicating that the data link is up and passing
data.
5.5 LOCAL Mode
An active Talkwire link has certain functions which enable you to
command the actions of a remote SBU128 or other SmartSWITCH
BACKUP product without having full command of the remote unit. This
state is called Local Mode.
