supported by secretarial service and equipped with economical single-line phones.

When alternate resources	are	not	available	to handle an incoming call, System	25 provides
for attendant handling of	the	call	utilizing	camp-on, redirection and/or message	service.

●Camp-On allows the attendant to extend an outside call to a busy station. A burst of

tone is heard at the called station					to notify the user of the camped-on call. The
caller is placed		on	hold and hears		music-on-hold, if available. When the user hangs
up, the camped-on			call begins ringing immediately. Only one call may be camped on
at	a time. The	Return Coverage		on	Busy feature returns unanswered camped-on calls
to	the attendant	for	service after	a	specified interval.

●Return Coverage on Don’t Answer returns unanswered attendant-extended calls for additional service (redirection/messaging).

●Messaging Service supports activation of an LED at the called station to indicate that the attendant, message desk, or another station has a message for the user.

Special arrangements are needed to handle incoming calls during periods when the normal staff is not available, for example at night and on weekends. System 25’s Night Service feature allows on-duty personnel to answer incoming attendant-seeking calls when the attendant is not on duty. Directed Night Service redirects incoming attendant-seeking calls to designated voice terminals, such as a guard desk or coverage position. Trunk Answer From Any Station allows users to answer incoming calls from any station by dialing the Night Service access code. Night personnel can be alerted by a Night Bell.

Outgoing Business Communications

One of the key functions of a customer premises communications system is to provide easy access to the most cost effective network facilities for outgoing calls. The system needs to be capable of steering calls based on cost, and must also keep records of incoming and outgoing calls and associated costs. Building on its ground start trunk capability, System 25 features control costs and record usage as follows.

●Call Restrictions allow the manager to restrict users from making certain types of calls. Restriction is administered through outward restriction, toll call restriction,

and facility access restriction.

●Automatic Route Selection provides manager defined routing of calls over the telecommunications network based on preferred routes (normally the least expensive route available at the time the call is placed) with capacity for multiple common

carriers and routing through tandem switch points. The user dials a standard DDD number and the system selects the call route.

●Station Message Detail Recording (SMDR) generates detailed call information on all incoming and outgoing calls and sends this information to an output device (PC or printer).

●Account Code Entry allows a user to associate calls with an account code for charge- back purposes.
