KBU 64
User Manual
80-10100000-097–2
1. TALKWIRE must be set to ON at both ends of the required link.
2. Your KBU 64 is a dual channel device, serving two separate Kilostream
links, each with an ISDN backup channel. Talkwire can operate over the
ISDN or the Kilostream link, but can not use the same path being used to
transmit user data. Both channels within your KBU 64 have Talkwire
capability, both can simultaneously be using a Talkwire session if
Talkwire is set to Local mode, however, only one Talkwire session can
be enabled when using Remote mode. Treating each channel separately,
if data is being passed over the Kilostream link of channel 1 a Talkwire
call can only be dialled over the ISDN. If USER 1 is connected to the
ISDN, then Talkwire can only be used on the Kilostream link, and only if
the link is operational.
3. A Talkwire call (over the ISDN) can only be answered by a remote KBU
64 if the ANSWER parameter of the remote unit is set to AUTO. By
default, the ANSWER parameter is set to AUTO.
Alternatively, if the ANSWER parameter is set to CLID, the call will be
accepted if the CLID of the remote KBU, matches the ISDN number of
the channel from which you are placing the call.
The connect parameter must be set to MAN at both the local and remote
KBU 64s, if you do not wish to re-direct the data path away from the
Kilostream line during a talkwire call.
7.2 Enabling / Disabling the Talkwire Facility
By default, the Talkwire facility is enabled. To enable or disable Talkwire
on a given channel, from the command line prompt of the required
channel, type:
1> SET TALKWIRE xx[CR]
where:
xx is ‘ON’ or ‘OFF’
Note: When Talkwire is enabled, the KBU 64's STATUS[CR] screen will
display TALKWIRE as either DEAD or ACTIVE.
DEAD indicates that the facility is enabled but a talkwire session is not in
progress (no data path).
