Cable Routing Guidelines
‘‘Cable Routing to Top Terminal Blocks’’ on page 120 and ‘‘Cable Routing to Bottom Terminal
Blocks’’ on page 121 show typical cable routing from the media gateway to the top and bottom
of the MDF, respectively.
Use these guidelines when routing cables from the media gateway to the MDF. Following these
guidelines will maximize use of the cable slack managers and make future cabling additions and
changes easier.
• Connect each port cable at the media gateway, and then route it along the front trough of
the cable slack manager to the connecting/terminal block, where the cable is terminated.
• Leave enough slack at the media gateway end of the cable to allow for proper dressing of
the cables.
• Route the cable from the media gateway to the wall. Place the cable beside 1 of the rows
of columns in the cable slack manager.
NOTE:
Retainers mounted on the columns keep the cable from protruding above the top of the
base of the cable slack manager.
• Determine the length of the cable required to reach from the cable slack manager to the
assigned connecting/terminal block.
• Use D rings on the wall to support the cable. (The cable must be supported.)
•
Coil the cable around the columns in the cable slack manager to store cable slack. The
first run should always go across the full length of the 5 columns in the cable slack
manager.
• Connect the cable to the assigned connecting/terminal block.
•
Avoid placing copper cables where they may bend or strain fiber optic cables.
Control Carrier Outputs Cable Installation
In an MCC1 and SCC1 media gateway, a connector on the rear of the Expansion Control Carrier
is labeled AUX. A 25-pair cable connects the AUX connector to a 110-type terminal block in
the yellow field of the trunk/auxiliary field. The AUX connector outputs include the following:
• 7 DC power (-48 VDC) sources for emergency transfer units
•
3 DC power (-48 VDC) sources for remotely powering a total of 3 attendant consoles or
executive telephone adjuncts
