Connect to Line Interface - PBX
Since there are many different PBX devices and connection methods, your individual PBX will determine the
connection method you use to connect to the unit. For example, your PBX may be connected using a patch
panel, punch down block, wire wrapped blocks, etc. If you are not sure about installation procedures, contact
the network administrator or review the documentation you received with the PBX.
Adjacent port pairs (i.e., 1/2, 3/4, etc.) are configured by default to connect to each other (power off bypass)
when the unit is turned off, or when the unit is in Offline mode. This is the preferred method when connecting
one of the lines to a PBX, and its adjacent pair to the PSTN. However, if you have adjacent port pairs that are
connected to smaller devices (i.e., both going to PSTN) in which you do not want the two ports to be con-
nected to each other in case of power off or offline, you should set the power off bypass = 0. Each pair of ports
(1/2, 3/4, 5/6 and 7/8) have their own online/offline and power off bypass control. See the
Tenor
Configuration
Manager
online help or the
Command Line Interface (CLI)
guide for specific configuration information.
You may use your PBX documentation, along with other PBX materials, to determine how to connect the
other end of the RJ-45 cable to your PBX. See
Chapter 2: Hardware Components
for the RJ-45 cable pinouts
you can use to acquire another cable or adapter that may be required to connect your specific PBX to the unit.
No changes are required to the PBX itself; you will need only the correct cable or adapter.
The instructions which follow tell you how to connect an RJ-45 cable (included in your package) between one
of the eight network ports on the
Tenor DX
and a PBX. See
Chapter 2: Hardware Components
for a list of RJ-
45 cable pinouts you can use to make a custom cable.
Figure 3-4
Connect to Line Interface
Connect to Line Interface as follows:
1. Plug one end of the crossover RJ-45 cable into one of the eight network ports on the front of the unit. (This
cable from Quintum would be the red RJ-45 crossover cable.) See
Chapter 2: Hardware Components
for
cable pinouts if you are making your own cable.
2. Connect the other end of the crossover RJ-45 cable into the appropriate port on the PBX. (If another cable
or adapter is required, see
Chapter 2: Hardware Components
for RJ-45 crossover pinout information.)
NOTE:
If you are connecting to an external CSU, ensure the Digital Interface is configured as short haul (or
DSX-1); otherwise, configure the Digital Interface to DS-1 to enable the built in CSU via Com-
mand Line Interface (CLI). See
