4.9.4 Internal
The internal function is used when network equipment is set for Eternal Timing (see
Figures 4-10 and 4-11). When connecting KG or KIV encryptors together on the Black
side, you should install the internal strapped header in the J3 position. In this applica-
tion, the modems are acting as the network timing source. In most cases, both modems
should be set for internal master clock. The rate switches should be set to the appropri-
ate speed for the circuit. This header is provided with the interface.
