Canoga Perkins
4.9.5 External
The External function is used when network equipment is set for Network or Inter-
nal Timing (see Figures 4-12 and 4-13). When connecting KG or KIV encryptors
on the Red side to a DTE device, you should install the external strapped header in
the J3 position. In this application, the modems are acting as an extension of the Red
side cable in a true tail circuit. The modem at the Red end is set for external clock
and the modem at the DTE end is set for slave clock. This header is provided with
the interface.
