Out-of-Building Voice Terminals (TN742, TN746B in R3V2)
A single-line voice terminal may be located in another building in a campus
environment within a loop resistance of less than 1300 ohms (including the voice
terminal). These terminals require primary and secondary protection devices.
Only a TN742 CP can be used.
1. At the remote location, connect the single-line terminal to a 103A
connecting block, using a modular telephone cord.
2. Using 4-pair inside wiring cable, connect the 103A connecting block to
primary and secondary protection devices. (See Table 2-B.)
3. Run the cable from the remote protection device to the System 25
equipment location.
