Miscellaneous Wiring Installation
off-premises stations. The TN746 analog line circuit pack cannot be used for
off-premises stations.
Installation
To install an off-premises station:
1.
2.
3.
4.
5.
Install a B25A cable between the RJ21X network interface and a
sneak fuse panel.
At the cross-connect field, connect jumper wires between one
row/connecting block in the green field and up to three
rows/connecting blocks in the purple field to concentrate the analog
line pairs as shown in Figure 3-56.
When 110-type hardware is used, connect an A25D cable between
the sneak fuse panel and the 110 terminal block connector
associated with the green row in step 3.
For 110-type hardware, install a green label on the 110-type terminal
block to identify the remote location. For 66-type hardware, write
the remote location lead designations on the connecting block with a
permanent felt-tipped pen.
Administer per AT&T System 75 and System 75 XE—Implementation
(555-200-651) and AT&T System 75 and System 75 XE—
Administration (555-200-500).
Installing Out-of-Building Campus Stations
Out-of-building campus stations are those telephones/voice terminals that are
not physically located in the same building as the PBX equipment room but
are located on the same property.
Both analog telephones and digital voice terminals can be used as out-of-
building stations.
Analog Out-of-Building Stations
Figure 4-22 shows the connections for one to eight off-premises analog
telephones. The TN746 analog line circuit pack cannot be used with off-
premise or out-of-building stations. Only analog telephones connected to
TN742 or TN769 analog line circuit packs can be installed out-of-building.
