Cable data
Standard telephony cables can be used (see table below).
Be aware of the following two cases:
•
If the cables are going to a distribution frame, an appropriate breakout cable can be
used (e.g. 16 × 2).
•
If the cables are connected directly to modems, 2 × 2 cables can be used where only
one pair is required.
