ADTRAN 25 manual Off-Premises Stations TN742, TN746B in R3V2

INSTALLATION

Off-Premises Stations (TN742, TN746B in R3V2)

An FCC-registered single-line terminal may be installed as an Off-Premises Station (OPS).

Note: Only the local telephone company can install the interconnections for the OPS.

The connections between the network interface and the 700A Jacks are described under “Connect Network Interfaces to TAE Jacks.” (Only the TN742 CP supports this feature.)

1.Trace the OPS pairs through the network interface to their termination on the TAE.

2.Install secondary wiring protectors. (See Table 2-B.)

3.Cut down one end of a cable pair on the 700A and the other to a 858A Adapter on the SIP.

4.Connect an octopus cable to a TN742 circuit pack.

5.Connect the octopus cable legs to the adapter wired in Step 3 above.

6.Document all connections.

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.
