Installation Note

Description

1. The TII 751-1T-01 is an Indoor Network
demarcation point device suitable for multi
dwelling units. When installed at the service
entry point phone outlet, the unit provides
access to the telephone company’s central
office signals while disconnecting the inside
premises wiring. This is accomplished by
accessing the test jack identified on the front
of each unit. A “full-time” phone jack is also
provided on each unit so that a telephone
connection may be established at the location.
The unit is equipped with a half-ringer test
circuit for remote testing.

2. The TII 751-1T-01 is a surface mount unit
which may be mounted to a wall surface.

3. If dial tone is not present, check connection to
the service wires from the telephone company.
Once the connections are verified and dial

service up to the Baseboard Jack is functional.
Remove the telephone plug from the test jack
and close the sliding cover.

5. Check for dial tone on all other telephones
within the premises. If the dial tone is audible,
the proper connections have been made.
