4.4.1. PBX Inputs A and B and AUX Port
The PBX Inputs and the AUX port are used for connection to your PBX
SMDR Port. The AUX Port can be connected to a third PBX, or used to
collect data from, or pass commands to other devices. For a description of
the port interface, please refer to Appendix B. Note that NLJ-VIP units do
not include PBX Port B or the AUX Port.
4.4.2. Modem Port
When an outside phone line is connected to the Modem Port, the VIP can
be managed and polled via modem. When an alarm is generated, the VIP
can also provide notiﬁcation via modem or pager.
4.4.3. Console Port
The Console Port can be connected to a local PC, which is used to manage
and poll the VIP unit. Please refer to Appendix B for a description of the
Console Port interface.
4.4.4. Network Port
The Network Port allows connection to a TCP/IP network. When
installation is complete, the VIP unit can be managed and polled via
network. The VIP can also provide alarm notiﬁcation via SNMP trap. Use
a straight wired 10Base-T cable.
Note: The VIP features a 10Base-T, half duplex network interface.
When connecting to a 100Base-T interface, most router switches
will autosense to determine if the device is 100Base-T or 10Base-
T, and then conﬁgure the network interface accordingly. If your
router switch does not autosense, the network interface port must be
manually set to 10Base-T, half duplex mode.
