Connecting analogue terminals
The M6501L/R IP PBX has analogue trunk lines that are designed to be compatible with various
types of equipment such as telephones, group 3 fax machines, modems, answering machines,
and voice mail systems.
They can be connected, via the distribution frame, to the following cards:
Connecting an analogue terminal
The requirements to connect an analogue terminal are:
• the voltage and current measured across the station during conversation must be: U >
12.4 V and I > 25 mA
• line resistance (taking the set into account): 600 Ohms
• line length:
0.4 mm wire:
approximately 2 km
0.6 mm wire:
approximately 3.5 km
• all the analogue terminals connected to the PBX must be configured for Zref impedance and
self-regulation.
The principle for wiring an analogue set is shown in the diagram below:
