INTERFACE FRAME
The TEL-14 line A circuit is connected to the matrix through the RJ-
45 connector on the interface rear-panel assembly that the TEL-14 is
connected to. The DB-9M connector immediately adjacent to the RJ-
45 is used to connect to the telephone line. Similarly, the second RJ-
45 and DB-9M connectors connect the TEL-14 Line B circuit. Clear-
Com provides DB-9F to RJ-11 adapters (CC# 770025) that allow the
use of common RJ-11 telephone jacks and cords.
Warning: The TEL-14 works with POTS (Plain Old Telephone Service)
CO (Central
Office) lines. Analog station lines in some
PABXs are not compatible.
Internal Settings and Adjustments
For internal option switch settings and adjustments, refer to the
“Setup” section in this chapter.
Connection To The Telephone Line
Connecting the telephone line can be accomplished with two
methods. One is to use the RJ-11 to DB-9M adapters supplied by
Clear-Com (CC#770025) with the TEL-14 interface. The second
method is to directly wire each telephone line to a DB-9 connector
using the pinouts in Figure 2-1.
Note the Clear-Com #770020 adapter, which may be alternately
supplied, does not have the wiring to pins 1 and 6 of the RJ-11
connector. If it is necessary to use a series-connected telephone set
with the TEL-14, contact the Service Department to obtain a
CC#770025 adapter instead. Figure 2-1 shows the wiring diagram
of the adapter for one line.

The phone line must be an outside (POTS) line directly connected to
the telephone company central office, and isolated from in-house
phone systems. A standard telephone can be installed in parallel with
this line if desired, but it should not be used while the TEL-14 is
offhook. When the TEL-14 is automatically adjusting its sidetone null,
all additional standard telephones must be "on-hook".
