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 — 25-pair connector on the white field and
field-terminated on the blue field
■ 110PE1-300FT — Field-terminated on both the white and blue fields
The 900-pair 110P-type terminal blocks that can be used are:
■ 110PE1-900CT/FT — 25-pair connector on the white field and
field-terminated on the blue field
■ 110PE1-900FT — Field-terminated on both the white and blue fields
Station Circuit Distribution from
Equipment Room
This section explains the station circuit distribution from the equipment room to
the information outlets for new wiring installations. Example connection diagrams
are provided to show the options for running and connecting the station cables.
If most of the telephones/voice terminals that require remote powering are within
250 feet (76.2 m) of the equipment room, 4-pair station circuits are run from the
equipment room to the information outlets. If this is not the case, or if the
customer requires 2-point administration, 3-pair station circuits are run from the
equipment room to satellite locations. Then, the 4-pair station circuits are run
from the satellite locations to the information outlets.
A list of voice and data terminals that can be connected to the system is
provided in Table 2-4 on page 2-40
. A list of administration terminals that can be
connected to the system is provided in Table 2-5 on page 2-44
