Note
Pins 1 and 6 are not used and should not be connected to the telephone system.
The connectors on the rear brackets of the D/120JCT-LS cards accept linecords
equipped with standard two-line RJ-14 connectors.
Depending on the type of linecord your local public telephone network uses, you may
need linecord adapters to connect the computer platform to the telephone system (switch).
If linecord adapters are required and not included with the linecards, please contact your
technical service representative.
To cable D/120JCT-LS cards:
•
Plug the linecords (jacks) from the telephone system to the RJ-14 connectors on the
D/120JCT-LS (refer to the line assignment diagram shown in Figure 9).
–or–
If the linecords from the telephone system do not use RJ-14 connectors, plug the
linecords into the appropriate linecord adapter, then plug the RJ-14 linecord(s) of the
adapter into the RJ-14 connectors on the D/120JCT-LS.
