Telephone System Wiring
The PC4851 connects to the telephone system via one RJ-71C connector per 12 phone
lines (two for each fully populated relay board). These cables must be wired by the tele-
phone company prior to installation. Table 1 defines the cable wiring required by the
phone company. Ensure that the phone company provides the Line Number and Apt.
Number information required in Table 2. This will enable management to assign directory
codes correctly.
