“OFF-AIR” TELCO MONITORING
Callers can be monitored during “off-air” Telco operations by means of the console CUE system, or an
external speaker connected to the Telco Mix Module’s variable Telco Monitor Output. When using the
console CUE system, depress the CUE button(s) on the module(s) being used as the Telco input(s) to
route caller audio to the console operator’s headphones (the CUE buttons will reset when the module
is turned ON). When connecting an external speaker, use a relay driven by the Control Room Warning
Tally, so that the speaker will mute whenever the Control Room is muted, as shown in Figure 5.3.
