Sneak Fuse Panels and Emergency Transfer Units

Approximately eight inches (20 cm) of horizontal wall space is required for each column of
sneak fuse panels. Horizontal wall space must also be provided for emergency transfer units.

110-Type Hardware

The trunk/auxiliary field and the distribution field are mounted on the same wall. Each
110P-type terminal block is 8.5 inches (21.6 cm) wide. Vertical patch cord troughs are 5.31
inches (13.4 cm) wide and horizontal patch cord troughs are 23 inches (58.4 cm) wide.
Each 110A-type terminal block is 10.81 inches (27.4 cm) wide; however, no horizontal patch
cord troughs are used and the blocks are shorter than 110P-type terminal blocks. This allows the
110A-type terminal blocks to be stacked. Therefore, the 110A-type hardware requires less space
than the 110P-type hardware on a per-station basis.

Cable Slack Manager

A Cable Slack Manager is 32 inches (81.3 cm) wide. Slack managers are commonly used in
installations consisting of media gateway stacks. The quantity of slack managers is determined
by dividing the total length of the Main Distribution Frame (MDF) in inches (cm) by 32 (81.3).
A partial number of 0.4 or less should be rounded down, and a partial number of 0.5 or more
should be rounded up (for example: 2.4 = 2 Cable Slack Managers and 2.5 = 3 Cable Slack
Managers).
NOTE:
Cable clamps are required in installations with Cable Slack Managers. At the rear of the
media gateways, on each rear ground plate, install two cable clamps using the screws
provided. These clamps hold the 25-pair input/output or Main Distribution Frame (MDF)
cables in place.
