The External function is used when network equipment is set for Network or Internal Timing (see
Figure 3-9). 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.
