2.19 Cabling Requirements

• Do not run extension 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.
• When cables must be run on the floor, cable protectors must be used.
• Cable runs for Multiline Telephones, DSS Consoles, Single Line Telephones, and Doorphone Boxes
must be a dedicated, isolated cable pair.
• Aerial distribution cabling is not allowed.
• Trunk Lines must be installed with lightning protectors.
• Do not use 4-wire cabling for SLT connections.
