Connection Requirements

The chassis is connected to each multiline terminal, single line telephone, optional
equipment, GCD-PVAA, DID/OPX, E&M Tie lines and digital trunks by a separate
twisted-pair cable through the Main Distribution Frame (MDF). The E&M Tie lines
are T1/FT1 lines and require multiple twisted pair cabling.

Cabling Precautions

When selecting cables and the MDF, future expansion or assignment changes
should be given due consideration. Avoid running cables in the following places:
A place exposed to the wind or rain.

A place near heat radiating equipment or where the PVC covering could be

affected by gases or chemicals.
An unstable place subject to vibration.
