TEL-14 TWO-CHANNEL TELEPHONE INTERFACE
It is preferable to use a series-connected telephone set with the TEL-
14. This will prevent the impedance of the telephone set from
disturbing the telephone line impedance recognized by the TEL-14. It
will also allow the TEL-14 to automatically disconnect the telephone
when it comes offhook. A standard telephone may be installed in
series with the TEL-14 by connecting it to pins 1 and 6 of the RJ-11
jack. Refer to Figure 2-2 for a diagram showing one way to connect
the TEL-14 in series with a telephone.
