Analog End Devices

Installing Cables and Wall Sockets at the Internal a/b Port

Requirements:

– Cover panel is removed

– Keeping the maximal distance/line length between the devices depending of the cable used

(with a pair diameter of 0.6 mm: approximately 790 m )

– Per a/b port, one wire pair of an installation cable (e. g. J-Y(St)Y 2x2x0,6)

– Under unfavorable conditions, for example, near a strong transmitter or an electrical power

line: screened cable

– For telephones or combination fax/answering machines: a TAE wall socket with F coding (a

single socket labeled with an F)

– For fax machines, modems, and call answering machines: a TAE wall socket with an

additional socket with N coding

Note: Outside of Germany, use RJ-45 sockets or the analog wall sockets

normally used in the country in question.

1. Lay the line.

Note: Prevent interferences. Avoid laying long lengths of parallel lines,

especially next to mains. Twist the pairs.

2. Attach the wires to the two terminal clamps at the internal a/b port.

3. Connect the wall sockets to the terminal clamps at the internal a/b port.

Warning: Power surges, which can occur during electrical storms, can

cause life-threatening electric shocks or damage/destroy the PBX.

• Lay all the cables inside the building.

• Do not use the a/b ports to connect external private branch exchanges.
