Cabling Requirements
1. Do not run station cable in parallel with the AC source, telex or computer, etc. If the cables are
near cable runs to those devices, use shielded cable with grounded shields or install the cable in
conduit.
2. When cables must be run on the floor, use cable protectors.
3. Cable runs for key telephones, single line telephones, Door Boxes, CTA or CTU adapters, and
2PGDAD Modules must be a dedicated, isolated cable pair.
4. The Telco RJ21X and cross-connect blocks should install to the right of the cabinet.
Extension blocks and cross-connect blocks should be installed to the left of the cabinet.

Using Under Carpet Cable:
The cable is not twisted, but flat parallel wire. Good impedance balance cannot be expected and reduces
the cable length to no more than 300m when using the flat cable.
