Integration Description
PBXLink Box Connections
A single PBXLink box is connected to the phone system with one or two digital phone lines and
connected to the Cisco Unity server with an RS-232 serial cable. The voice messaging lines from the
phone system connect to the analog voice cards in the Cisco Unity server. Figure 1 shows the required
connections.
Figure 1 Serial Connection Between a Single PBXLink Box and Cisco Unity
Multiple PBXLink boxes are connected to the Cisco Unity server by using an RS-232 cable to connect
the SMDI port from the last PBXLink box to the Management port of the first PBXLink box. Another
RS-232 cable is then used to connect the SMDI port of the first PBXLink box to the Cisco Unity server.
The voice messaging lines from the phone system connect to the analog voice cards in the Cisco Unity
server. Figure 2 shows the required connections.
