3. Connect an A25D cable between the sneak fuse panel and the terminal block connector
associated with the green row in the previous step.
4. Install a green label on the terminal block to identify the remote location.
5. Administer per the Administrator Guide for Avaya Communication Manager (03-300509).
Off-premises or out-of-building stations
Out-of-building campus stations are telephones not physically located in the same building as
the equipment room but located on the same property. Only analog telephones connected to
TN746B, TN791, TN793, TN793B, TN793CP, TN2183, TN2215, TN2793, or TN2793B Analog
Line circuit packs can be installed out-of-building.
Off-premises connections
Figure 44: Connections for 1 to 8 out-of-building analog telephones on page 92 shows the
connections for 1 to 8 off-premises analog telephones.
Figure 45: Connections to 24 out-of-building telephones on page 93 shows the connections for
up to 24 off-premises analog telephones. Concentrations of analog line pairs are used at both
buildings to minimize the off-premises wiring required. At the MDF, jumpers must be connected
between one row/connecting block in the white field and up to three rows/connecting blocks in
the purple field. At the station location, a WP-90929, List 1 Concentrator Cable is used. There
are eight station appearances on each of the three fingers of the concentrator cable.
The maximum distance from the media gateway to the out-of-building telephone is 6,000 feet
(1,829 meters) using 24 AWG (#5) (0.5 square millimeters) wire.
The maximum range of out-of-building analog telephones (500-, 2500-, or 7100-types)
connected to an analog line circuit pack should be such that the maximum loop resistance does
not exceed 1,300 ohms.
