Removing a CTI Link
Remove the ISDN link interface card, if desired.
Refer to the PC/ISDN Platform Installation and Reference, or similar
installation manual from the ISDN link interface card vendor.
Remove the MERLIN LEGEND administration.
Delete the MLX port from the list of CTI link ports, using MERLIN
LEGEND system programming (at the MLX-20L or SPM). After this, it is
safe to plug in an MLX telephone, a data module, or an ISDN terminal
adapter. See System Programming .
Link Shutdown
Temporarily idling a CTI link before performing maintenance is an optional
procedure on the server side; it can prevent unwanted MERLIN LEGEND
Communications System alarms. However, a link shutdown is not required
before performing maintenance.
For a link shutdown, perform the following steps:
Suspend MERLIN LEGEND alarming for the CTI link.
If Step 1 of the link shutdown is not performed, then the MERLIN
LEGEND may generate alarms about the CTI link while under
maintenance. See the MERLIN LEGEND System Manager's Guide for
detailed instructions on this procedure.
Prevent new CTI link traffic.
If Step 2 is not performed before working on the CTI link, an application
may get confused. For example, if an application sent a service request
(such as Make Call) but the CTI link is taken down for maintenance
before the MERLIN LEGEND sends a reply, the application will think the
request failed even if it succeeded. In contrast, if this step is performed,
the application will immediately receive a failure reply. See the MERLIN
LEGEND Network Manager's Guide for detailed instructions on the
Block, Offline, and mloam commands.
Wait for CTI link traffic to subside.
