4.7Since the IMX 256 System utilizes digital voice
and data transmission between the digital keysets and
the equipment cabinet, there are some additional digital
keyset-only cabling requirements:l Do not use shielded cable, and do not use cable
smaller than 24AWG.l
Do not parallel cables (i.e., do not “double up on the
COppX”).
0Do not “bridge” or “Y” off the cable to another loca-
tion.l Unlike analog 
keysets, the...

5.1The main distribution frame (IUDF) is the point at
which the station instruments, trunks, and auxiliary sys-
tem equipment are connected to terminal blocks (or, in
the case of 
Tl spans and optional Tl equipment, modu-lar jack assemblies are used instead). These terminal
blocks (or modular jacks) are then connected to the 256
System. It is extremely...
