PBX link
A PBX link may be needed to provide SMDI services for a legacy PBX that does not
offer support for SMDI. The CTL PBXLink provides integration services to allow
certain digital PBXs to interface seamlessly with a Voice Messaging System. The
PBXLink connects to the PBX using a digital telephone line and to the Voice Messaging
System using an RS-232 link. The PBXLink uses information appearing on the
emulated digital set to determine the original source and destination of the calls being
forwarded to the voice mail system. This information is then communicated to the
voice mail system on an RS-232 serial link using the industry standard "Centrex SMDI"
protocol. The PBXLink is compatible with SMDI-compatible voice mail systems.
