This means that he or she can arrange certain station ports together for SOHVA calling between one another while excluding other station ports in the system from this group.
Page 406: System Alarm Reports
Digital Telephone System IMI66–107 Example 1: Allow station port 10 to originate SOHVA messages to all stations in the system and allow those stations the ability to originate SOHVA messages to each other but not to station port 10. Assign group 1 to station port 10 and assign group 2 to all other station ports.
Page 407 IMI66–107 Digital Telephone System Tandem Attendant When the programmer uses system class of service programming to enable the tandem attendant feature, a recall from an unanswered call transfer or a timed hold recall will ring at the normal attendant station (station 10) that set the transfer or hold condition, and also ring at the tandem attendant station (station 12).
Page 408: Toll Restriction
Digital Telephone System IMI66–107 Toll Restriction Default Toll Restriction The system defaults two toll restriction tables with pre-programmed values and pre-assigned to all lines. The programmer needs only to assign these tables to the stations by programming action to put them into effect. He or she can use the toll restriction table configuration class of service programming to reprogram the defaulted tables with different information as needed.
Page 409: Toll Restriction Override
IMI66–107 Digital Telephone System tables replace any that he or she may have assigned to the station for normal, or day mode, operation. For example: a programmer can arrange for a station that has no other toll restriction table assignment to receive a toll restriction table which will restrict everything but local calls and will only take effect when the system is placed in the night transfer (of ringing) mode.

Digital Telephone System IMI66–107 Tracker Paging System The optional Tracker Paging System is a wireless paging system that uses an external base station connected to the common equipment cabinet and individual portable pagers assigned to the system station extension numbering plan. The Tracker Paging System allows telephone users to send alpha/numeric or numeric-only messages to Tracker pagers assigned to station extension numbers.
Page 411 This message and button fuctionality enhances the stations with visual messages and interactive buttons. This message and button functionality enhances the station’s use with Comdial Versatile Voice Processing (VVP) voice mail equipment. To implement VVM support, the system programmer must enable it with class of service programming action.

Digital Telephone System IMI66–107 Voice Announce Blocking This feature allows station users to block voice announced intercom signaling by dialing a code or pressing a programmable button programmed for that purpose. The programmable button used to block voice signaling is enabled by station class of service programming.
Page 413: Volume Control
IMI66–107 Digital Telephone System Positive Disconnect Supervision When a station is on line with an outside caller and the caller hangs up, the CO may send a positive disconnect signal to the digital telephone system. The system passes this signal to the voice mail equipment thus signaling it also to hang up.
Page 414 Digital Telephone System IMI66–107 ringer-off feature on a system-wide basis. When programmers take this option, users can set the ringer volume to a low level but cannot completely silence it. The number of handset loudness levels is different for the different telephone models. The DigiTech telephones have 8 handset volume settings.
