Abandoned Hold Release
If an on-hold party hangs up at the CO/PBX end of a connection, causing an interruption
in the line current, the system will drop the line from the hold condition and return it to
service. The time interval between hang-up and line-drop is programmable in line class
of service programming with choices of either 50 msec or 350 msec. This feature is
usually dependent upon special arrangements that must be made at the CO end of the
connection. The line select indicator will turn off to indicate an idle line after a call on
that line has been abandoned.
See also, Hold.
Access Denied
The system programmer can deny access to particular lines at certain stations in the
system. A station user cannot select a denied line for use. This feature is programmable
on a per line/per station basis in station class of service programming.

  • Page 2 IMI66–132 DSU II Digital Telephone System Account Codes (With Forced Positive Verification) System users can employ account codes to identify calls by category or by any other desired grouping so that the system can print reports. The account code entry can be voluntary or the programmer can arrange the system so that the users are forced to enter an account code before they can make an outgoing call.
  • Page 3 DSU II Digital Telephone System IMI66–132 but cannot be lower than the verified account code length. The verified account code length defines the number of digits that the system will verify before it accepts an account code as valid. As well, verified account code length defines the number of valid account codes that a programmer can store (as shown in the following table).

    DSU II Digital Telephone System IMI66–132 Automatic Hold For Intercom If a user selects the second intercom line while a call is active on the first intercom line, this automatic hold feature lets the system automatically place the first intercom call on hold.
  • Page 8: Automatic Station Relocation

    IMI66–132 DSU II Digital Telephone System Automatic Station Relocation With this feature, the system will automatically recognize a particular station should that station be relocated to a new station port. When someone places a telephone at a new port location, it will continue to provide the same class of service parameters and respond to the same extension numbers as it did at the original station port.
  • Page 9: Background Music

    DSU II Digital Telephone System IMI66–132 Background Music If the installer connects a customer-provided external music source to the system, the music from that source will sound through the station loudspeakers after the users turn it on at their stations. They can adjust the loudness of this background music with the loudspeaker volume control.

  • Page 12: Call Forwarding On All Calls

    IMI66–132 DSU II Digital Telephone System Call Forwarding Call Forwarding On All Calls This feature allows a station user to designate another station or the attendant station as the recipient of all calls normally directed to ring at his or her station. If the user has call forwarding enabled when the attendant activates night transfer of ringing, the system forwards the night ringing assignment of the user’s station.
  • Page 13 DSU II Digital Telephone System IMI66–132 To enable this feature enhancement, programmers must first enable tone first signalling and arrange an intercom hunt group. Then, they can individually enable call forwarding for RNA calls and call forwaring for busy calls. They can turn on either call forwarding scheme alone or turn on both schemes as the site demands dictate.

  • Page 26 IMI66–132 DSU II Digital Telephone System dropped by the caller. The caller continues to receive ringback tone until the call is answered. The overflow station can service the call or transfer it back to the department using the department pilot number. When the call is transferred back to the department by an overflow station, it will not return to the overflow station until that station is idle and has no ringing calls either new or transferred.
  • Page 27 DSU II Digital Telephone System IMI66–132 A department station can also be taken out of service and placed in a wrap-up mode to provide the user time for doing such things as follow-up paperwork. While a station is in a wrap-up mode, all outside and transferred calls skip to the next department station. The station user sets the wrap-up mode by pressing Hold DND and presses these buttons again to clear the wrap-up mode.
