1.2 RJ71C Phone Block Installation
The RJ71C wiring configuration is not recognized by all telephone companies. For Bell Canada,
which has jurisdiction for Ontario and Quebec, refer to CA-79X jack for interconnect to the 1820
system. For BC Tel, which has jurisdiction in British Columbia, refer to BC Tel CRTC Spec 182 B5.
1.
Place the order for the RJ71C phone block installation with the local telephone
company at least three weeks in advance of the 1820 system installation.
2.
Order one (1) RJ71C block for every 12 telephone lines that the 1820 system will
inter-connect with.
3.
Have all required blocks installed in a common accessible location. This is usually
near the original phone company termination board.
4.
Be sure there the RJ71C blocks are mounted within 15 feet of where the main and
auxiliary cabinet(s) are to be installed.
supplied by DoorKing is 15 feet. If longer cables are required, special length cables
will have to be ordered at an additional cost.
5.
IMPORTANT!! Complete the RJ71C block identification form in the back of this
manual. This form instructs the telephone company installer how the phone lines
should be wired to the RJ71C blocks. Make copies of the form if more are required.
6.
IMPORTANT!! Be sure that the phone company installer labels the blocks! Each
block should be numbered, and the phone number and apartment number should be
written on the inside of the block cover (see example below).
7.
Attach the RJ71C block identification form to the inside door of the 1820 cabinet after
wiring is complete for future reference.
8.
CALL DOWN!! For the call down feature and programming from the resident phone
to function, the resident must have active telephone service. If the resident does not
have active telephone service, then a special Powered RJ-71C (P/N 1820-047)
phone block is needed. See section 2.3 for detail.
