Indication of Camp-On
Indication of Camp-On is an audible tone generated by the telephone system. Attendant camp-on service allows an electronic switching system Centrex attendant to hold incoming calls to busy lines. Each time the attendant releases his/her talking connection from the loop involved in the camped-on call, the indication of camp-on tone is heard by the called customer if the customer has subscribed to the indication of camp-on option. The customer may get this tone several times as the attendant reconnects and releases from the loop in response to timed reminders from the console. Indication of Camp On tone is at 440 Hz and -13 dBm0/frequency for one second every time the attendant releases from the loop.
