OUT-OF-BUILDING STATIONS
Description
Single-line voice terminals and multiline 7300H series terminals may be directly connected
to the system even though they are not located in the same building. For 7300H series
terminals special In-Range Out of Building (IROB) units are used to protect the switch and
its users from lightning, power crosses, etc.
Out-Of-Building Stations can access all system
features.
Considerations
Single-line voice terminals may be located at distances up to 24000 feet from the system
cabinets. Carbon protection devices are required for lightning and power cross protection.
Multiline voice terminals must be located within 2000 feet of the system cabinets (local
power required beyond l000 feet) and must have IROB protection devices. MET sets may not
be used for Out-Of-Building service.
Interactions
None
Administration Requirements
None
Hardware Requirements:
Out-Of-Building multiline voice terminals require IROB units. Single-1ine voice terminals
require carbon protection devices and must be connected to ports on the TN742 Analog Line
CP. Connectivity information is provided in Section 4, “Hardware Description.”
