3. Unplug the CTI link.
4. 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.
5. Remove the MERLIN MAGIX administration.
Delete the MLX port from the list of CTI link ports, using MERLIN MAGIX system programming
(at the 4425LD+ or MLX-20L console, or with WinSPM). After this, it is safe to plug in an MLX
telephone, a data module, or an ISDN terminal adapter. See the CTI feature in Feature
Reference.
Link Shutdown
Temporarily idling a CTI link before performing maintenance is an optional procedure on the server
side; it can prevent unwanted MERLIN MAGIX system alarms. However, a link shutdown is not
required before performing maintenance.
For a link shutdown, perform the following steps:
1. Suspend MERLIN MAGIX alarming for the CTI link.
If Step 1 of the link shutdown is not performed, then the MERLIN MAGIX may generate alarms
about the CTI link while under maintenance. See the MERLIN MAGIX PBX Driver Network
Manager's Guide for detailed instructions on this procedure.
2. 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 MAGIX 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 MAGIX PBX Network Manager's Guide
for detailed instructions on the Block, Offline, and mloam commands.
3. Wait for CTI link traffic to subside.
4. If the Offline or mloam command was used in Step 2, skip to Step 4.This step applies only if
the Block command was used in Step 2.
5. Determine when traffic has stopped. On the NetWare server, start the mloam or wmloam tool,
then go to the Link Status screen. View the line CTI Link Msg. Rate . If the value shown is
0, then traffic on the link has stopped. Refer to the MERLIN MAGIX PBX Network Manager's
Guide for details.
6. Unplug the CTI link or perform appropriate maintenance.
