is operating in ring plan 3, the RP3 button will light steady red, and when offthe light will also turn off.CALLING THE SYSTEM OPERATORAny station that dials 0 will ring its assigned operator. (If tenant service isused, each tenant may have a different operator or operator group.) Calls tothe system or tenant operator are easily identified because the CALL key willhave a fast flashing red light. Station users will never receive a busy signalwhen they dial 0 or the operator group number. The calls will continue ring-ing in queue until answered.OPERATOR RECALLSTransferred calls that go unanswered will recall to the station that originatedthe transfer. Should the station that originated the transfer not answer the re-call, the call will be sent to the operator as a transfer recall.A call left on hold will recall the station that put it on hold. If the hold recall isunanswered at the station that originated the hold, the call is sent to the oper-ator.Both types of recalls will ring and have a slow flashing amber light on theLINE key or CALL key.EXECUTIVE BARGE-INIf you want to break into another conversation, you must be allowed tobarge-in and the other station or trunk must not be secure.• Dial the desired extension or trunk number and listen for the busy sig-nal.• Press the BARGE button and begin speaking after the tone.• Hang up when you are finished.The system can be set for one of the three following barge-in options:• No barge-in allowed• Barge-in with intrusion tone• Barge-in without intrusion tone (service observing)When the second or third option is selected the barger will take priority overthe line. This means unless you (barger) hang up first, the station or line youbarged into will still be connected to you when the station you barged intohangs up.32SPECIAL FEATURESSYSTEM RING PLANSYour system is designed to have a maximum of six different Ring Plans. Eachring plan can be programmed to allow different lines to ring different ringplans to ring different station and/or station groups. Examples of why differ-ent ring plans are required can include normal day operation, night opera-tion, using different operators during different lunch shifts and Saturday orevening hours of operation. While the system is in a ring plan, each stationwill be limited to its individual Ring Plan class of service dialing restrictions.You can place the system in one of any six of these ring plans at any time.Ring Plans are available on an individual tenant basis and may be set auto-matically or manually. Automatic Ring Plans have an individual start time andwill remain in that mode until the beginning of the next defined ring plan. Ifno automatic timer is set, you must change ring plans manually.Any of these ring plans can be switched from one plan to another at any timeby manually pressing a ring plan button. There are two ways to override theautomatic ring plans; one is a temporary override until the next programmedstart time, and the other is a permanent override until manually changed.MANUAL RING PLAN CHANGEPress the RTO button plus the ring plan passcode (four digits) and the ringplan (1-6) you wish to set. The system will override all the automatic timetables and will remain in the set ring plan until manually changed. To manu-ally change or cancel the ring plan time override and return ring plan opera-tion to the system clock: press the RTO plus the ring plan passcode (fourdigits) and a “0” to cancel the ring plan time override and return to normaloperation.TEMPORARY RING PLAN CHANGEPress the RP button plus the ring plan passcode (four digits) and the ringplan (1-6) you wish to set. The system will remain in that ring plan until thenext automatic start time for the next ring plan goes into effect.NOTE: This button may also be assigned an extender of one of the six ringplans. Example: An RP button is given an extender of 3 (RP3) and the oper-ation of this button is a push on/push off type of operation with the systemalways returning to ring plan 1 when the key is turned off.
