7.1 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.
7.2 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.
7.3 Wiring Between the Chassis and the MDF
7.3.1 Chassis Cables
The chassis is equipped with two MDF Cable Assemblies. NEC
recommends that the MDF Cable Assembly be used to connect the
multiline terminals, single line telephones (except PFT), PVAA and DID/
OPX lines. Refer to
Figure 4-40 MDF Pin-Out (Connectors 1~6) and Table
4-40 MDF Cable Connections (Station) on page 4-100 or Table 4-41 MDF
Cable Connections (Trunk) on page 4-102 . When installing E&M Tie lines,
single line telephones with PFT, and other optional equipment with the
GCD-8DLCA/GCD-16DLCA, the connector and cabling must be locally
provided.
