7.5.7.1 Station Hunt Group 
Description: 
Up to eight hunt groups may be assigned. Hunting is always in a linear fashion. Each Hunt 
Group can contain 24 members. Hunt Group directory numbers are 82-89. One Hunt Group 
may be assigned as a Voice Mail type Hunt Group for system voice mail integrated operation. 
There are three data fields in hunt group programming; GROUP TYPE, GROUP MEMBER 
and RING ASSIGNMENT. 
GROUP TYPE available settings are; HUNT, VM and ALLRG. A Hunt Group assigned as 
type HUNT will perform a search for the first available, idle telephone member of the hunt 
group according to the order of programmed entry. A Hunt Group assigned as type VM will 
integrate voice mail control digits for calls placed to the hunt group. Only one VM type hunt 
group is allowed per system. The members of this hunt group should only be SLT ports and 
those ports should also be marked as VM type in Station programming. Finally, a hunt group 
assigned as type ALLRG will ring all telephone members simultaneously when the hunt group 
number is dialed. 
GROUP MEMBER is used to program the station members of this hunt group. 
RING 
ASSIGNMENT is used to program ringing of CO lines into this hunt group. 
RING ASSIGNMENT is used to assign ringing of CO lines to a hunt group. Ringing may be 
programming individually for each of the 12 CO lines and each of the 8 hunt groups. Ringing is 
available for the various modes of operation (Day, Night, Both).

7.5.7.2 Voice Mail 
Description: 
When a voice mail system is connected to the Star-plus DHS via SLT ports the operation of the 
voice mail system can be greatly enhanced by preprogramming digit code strings that allow the 
caller entering voice mail to be diverted to the appropriate menu level. The code that must be 
entered may be different depending on the call type (CO transfer to VM, intercom call to VM, 
etc.) . 
The Star-plus DHS provides six code strings fields; ICM PREFIX, XFR PREFIX, RECORD 
DGT, ICM SUFFIX, XFR SUFFIX and DIS DGT. The Starplus DHS always sends the station 
directory number to the voice mail system for calls that are forwarded to VM from a station. 
These digits are either preceded or appended with the digits programmed into the six fields. 
ICM PREFIX (Intercom Prefix) digits are digits that must proceed the station directory number 
when a station user calls VM to retrieve messages. When programmed correctly the station user -. 
will be delivered to his voice mail box and prompted to enter his password. The Intercom 
Prefix may be 4 digits in length. 
184 Installation & Maintenance Manual Revision 2 July 6, 1997  
						

							XFR PREFIX (Transfer Prefix) digits are digits that must proceed the station directory number 
when a CO line call is transferred to VM. When programmed correctly a call that is transferred 
to VM will be prompted by the station users mail box greeting prompt and may leave a 
message without further dial code digit entry. The Transfer Prefix may be 4 digits in length. 
RECORD DGT (Record Digits), these digits are sent to the VM system to speed the connection 
at the voice record level. These digits are used only with the Voice Recorder feature. When a 
key telephone station user wants to record a call he may invoke the Voice Recorder feature to 
do so. The RECORD DGT digits are sent to the VM system after the voice mail box digits to 
skip the user’s introduction and begin recording. 
ICM SUFFIX (Intercom Suffix) these digits are applied to intercom calls placed to the VM 
system as an aid to direct the caller to his personal greeting where he is required to enter only 
his password to retrieve messages. Digits programmed as Suffix Digits will be appended to the 
station directory number. That is, after the station directory number is sent to the VM system 
the Suffix Digits will then be sent. The Suffix may be 2 digits in length. 
XFR SUFFIX (Transfer Suffix) these digits are applied to calls that are transferred to the VM 
system. They are used to direct the caller to the mailbox owners greeting and subsequent 
message recorder. Digits programmed as Transfer Suffix digits will be appended to the station 
directory number. That is, after the station directory number is sent to the VM system the Suffix 
Digits will then be sent. The Suffix may be 2 digits in length. 
DIS DGT (Disconnect Digits) these digits will be sent (without station directory number digits) 
to the voice mail system whenever a station user listening to voice messages disconnects or 
when a CO line caller hangs up while leaving or listening to messages. The purpose of the 
Disconnect Digits is to make the voice mail port available to new voice mail callers quickly. 
Disconnect Digits may be 8 digits in length.

							8. MAINTENANCE AND TROUBLE 
SHOOTING 
Maintaining the Stat-plus DHS digital telephone system is a combination of customer database 
changes, facilities and apparatus moves, adds and changes. These requirements are handled 
properly by practicing the techniques, illustrations and step-by-step instructions listed in the 
previous sections of this manual. 
When installed properly the Starplus DHS performs relatively maintenance-free. From time to 
time the digital telephone instruments may become dirty or dusty and require cleaning. We . 
suggest the use of a clean, dry cotton (or other soft, absorbent) cloth to wipe the instrument 
clean. Use of chemicals to clean the telephone plastics is NOT recommended since some 
chemicals can cause permanent damage to the telephone finish. If deep soiling conditions exist 
for the telephone to be cleaned, use of specialized telephony cleaning solutions may give 
satisfactory results. When trying any cleaner for the first time we suggest that it be applied to the 
telephone instrument underside in a small sample area to assure that the desired results are 
obtained before proceeding. 
The System trouble-shooting procedures is a logical approach to fault identification, analysis, 
and correction. The key system may generate symptoms of problems that actually occur outside 
of the office environment. Problems such as system restarts (from temporary AC power 
interruption), fading (from the long distance carrier), or dropped calls (caused by internal user 
randomly pressing holding CO Line buttons) all are common situations that are not the result of 
a system component or software failure. 
The System Trouble-shooting Section attempts to provide the service technician with some 
quick, and reliable, tools to diagnose installation related or service related problem reports.
