Closets

Closets are intermediate points between the Main Distribution Field and the endpoint. They are used to
distribute wiring to multiple destinations via cross-connect equipment.
There are two different types of closet configurations. Satellite closets are usually distribution points for
multiple site closets. However, information outlets may be wired directly to a satellite closet. Site closets
are the last cross-connection point before the end user information outlet. Satellite and site closets may be
used to apply bulk station power to information outlets.

Satellite locations

Satellite locations are closets that provide an administration point (using cross-connect equipment) for
station cables and where adjunct power may be applied. The station cable circuits from the equipment
room MDF are 3-pair. At the satellite location, 4-pair circuits run to the information outlets. The
hardware used is 110-type terminal blocks.
Satellite locations using 110-type hardware
Each terminal block has a 3-pair (white field) and a 4-pair (blue field) located on the same terminal block.
The 110A-type terminal block that can be used is the 110AE1-75FT. It must be field-terminated to both
the white and blue fields.
The 300-pair 110P-type terminal blocks that can be used are:
•
110PE1-300CT/FT
•
110PE1-300FT
