Computer Telephony Integration (CTI) Link 4
Release 5.0 and later supports the use of an MLX port as a Computer Telephony
Integration (CTI) link. The CTI link allows applications residing on client PCs on a
LAN to communicate more easily with the MERLIN LEGEND Communications
System over a network that has a PassageWay Telephony Server for NetWare.
Before programming a CTI link, you should read the
Feature Reference
and the
PassageWay Telephony Services Network Manager’s Guide.
The following constraints apply to programming an MLX port as a CTI link:
■ CTI links cannot be used with communications systems operating in Key
mode or Behind Switch mode.
■ CTI link extensions cannot be programmed on tip/ring or analog multiline
extension module ports. You must chose an extension that is on an MLX
port module (008 MLX or 408 MLX).
■ You cannot use a port reserved for an operator extension as the CTI link
extension.
■ You cannot use a system programming port as the CTI link extension.
■ You cannot program a port as a CTI link if it has a telephone or other
equipment connected to it.
■ MLX modules with firmware vintage 29 do not work correctly with the CTI
link. You must either choose a port on a board with firmware vintage that is
not 29 or replace the module with a module that has a firmware vintage
other than 29.
NOTES:
1. You should choose a module other than the one that has the system
programming port so that you can still perform maintenance and system
programming when the board with the CTI link extension is busied-out.
2. Be sure to busy-out the board with the CTI link before starting any
programming activities.
When you add a CTI link, the system performs the following actions:
■ The programmed buttons for that extension revert to the default for a non-
operator MLX telephone.
■ Forwarding is deactivated to the extension.
■ The extension is removed form membership in calling groups.
■ The extension is removed from membership in coverage groups.
■ The Extension Directory label for the extension is changed to .
■ The default for alarms is active on this link.
■ Dial access to pools is removed from the station.
