4.15.5 DISCONNECT Timer
When DISCONNECT is set to MAN (default/normal) this timer is not
used.
However, if DISCONNECT has been set to AUTO, this defines the time
your KBU 64 will wait before disconnecting the USER port (data traffic)
from the ISDN line:
1> SET DELAY DISCONNECT xx[CR]
where
xxx
is the time in seconds (0 to 999).
4.15.6 TALKWIRE Timer
Defines the length of time your KBU 64 will wait for Talkwire to establish
a link, before reverting to non-Talkwire operation:
1> SET DELAY TALKWIRE xx[CR]
where
xxx
is the time in seconds (0 to 999).
Note: Talkwire will time out at the expiry of this delay period.
If this occurs during a backup call the ISDN call will be released and re-
dialled again (with CONNECT parameter set to MANual).
4.15.7 ALARM Timer
This timer is not used.
4.15.8 NTU Timer
The KBU 64 monitors the control signal Indicate/Data Set Ready (I/
DSR) on the LINK port, and initiates a backup to the ISDN line (when
BACKUP is set to AUTO).
Backup immediately starts when the I/DSR signal goes LOW. The NTU
timer defines how long the I/DSR signal must remain HIGH before
restoration of the leased line circuit is initiated:
1> SET DELAY NTU xxx[CR]
