11. PBX Cascading
As requirements grow, the OpenCom 100 can be operated together with other
PBX installations. If you merely need a larger number of connections, it is easy to
link a second PBX (PBX Cascading). If you want to operate the OpenCom 100 at
several locations with different PBXs, this is possible by PBX Networking (see
page 127).
Note:
It is not possible to cascade an OpenCom 131 with
another communications system.
11.1
Variants of PBX Cascading
You can combine two PBXs in order to increase the number of terminals that can
be connected. A master PBX and a slave PBX are connected to one another by
means of two cables. The two PBXs essentially function like a single PBX with a
higher number of ports. The master PBX controls the slave PBX. The following PBXs
from the product family can be used for cascading:
For the PBX Cascading you will need a license. The license agreement provides you
with the necessary steps to activate this function.
11.2
Functionality of PBX Cascading
PBX cascading requires two twisted-pair leads with RJ45 plugs between the PBXs:
■
Voice data: one lead with all eight pins wired 1 to 1. Connect this to the PCM
ports of the PBXs. The shielded CAT-5 lead may be up to three meters long.
The PCM port is on the add-on module of the OpenCom 130. You must
therefore install an add-on module in each of the two PBXs before they can be
cascaded.
■
Administration data: one CAT-5 Ethernet lead.
