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 (LIM - LIM).
For more information about cables see Page 17, see Section 5.8 Extension
Cable Structure on page 110, and for extensions see the subsections in this
section.
The cable length from the exchange to the MDF shall not be shorter than 3
metres (118 inches).
