Off-Premises or Out-of-Building Stations
Return to Task List
Out-of-building campus stations are telephones/voice terminals not physically located in the same
building as the equipment room but located on the same property. Only analog telephones connected to
TN742, TN746B, TN2183, or TN769 Analog Line circuit packs can be installed out-of-building.

Return to Task List
Figure 203, Connections for 1 to 8 Out-of-Building Analog Telephones, on page 527 shows the
connections for 1 to 8 off-premises analog telephones.
Figure 204, Connections to 24 Out-of-Building Telephones, on page 528 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 1
row/connecting block in the white field and up to 3 rows/connecting blocks in the purple field. At the
station location, a WP-90929, List 1 Concentrator Cable is used. There are 8 station appearances on each
of the 3 fingers of the concentrator cable.
The maximum distance from the system cabinet to the out-of-building voice terminal is 6000 feet (1828.8
meters) using 24 AWG (#5) (0.5 mm
2
) 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 1300 ohms.
