CONNECTION OF EXTERNAL CABLES

GENERAL
Cabling to the MDF uses prefabricated cables.
Twisted, shielded, pair-cables are to be used for cabling between the PBX and MDF or
PBX and PBX (Media Gateway - Media Gateway).
The cable length from the exchange to the MDF shall not be shorter than 3 meters (118
inches).

LINE LENGTHS

ELU26
The following three connection alternatives are based on the usage of a 75 ohm
twisted pair cable, 120 nF/km and wire 0.6 mm or a 150 ohm twisted pair cable,
30 nF/km and wire 0.6 mm or 125 ohm/km DC.
• 1000 m, point-to-point with one terminal.
• 500 m, extended passive bus with 8 terminals.
• 100 m, short passive bus with 8 terminals.
