•
this relocation feature only applies to digital telephones,
•
users must ensure that the vacated port remains unused until they complete a relocation,
•
if someone connects a telephone to the vacated port before users complete a relocation, the
relocated telephone will not retain its original programming,
•
when the user accept the original programming for the new port, the vacated port assumes the
programming currently assigned to the new port (that is, a parameter exchange takes place
between the vacated port and the new port),
•
if a DSS/BLF console was assigned to the telephone at its original location, the console
assignment follows the telephone to the new location even though the console is no longer
located physically near the telephone. If the user relocates the console, the system installer
must reprogram the new port for console use.
The relocation feature also applies to relocated digital telephone boards, however, the installer must
ensure that the vacated port remains unused until the relocation is complete. All stations connected
to the relocated circuit board show the relocation prompt.
Auxiliary Equipment Interface (Busy Lead Detection)
One line port on every loop start line board will detect current flow on the line ahead of the common
equipment. When an external device, such as a modem or fax, is connected to this line and is
activated, current flow over the line occurs. When the port detects the current flow, the system
causes a busy indication for this line to appear at every system telephone that has its appearance.
Normally, the user cannot interrupt an external device by pressing the line button or by dialing a line
group code; however, if the line is programmed to be non-private, a user can interrupt the device.
Auxiliary Station Ringer Interface
The central processor unit circuit board includes four dry-contact relay actuations. They may be used
for the following:
•
Programmable Station Ringer Interface
•
Paging Enable
•
Door Relay Lock/Unlock
•
Zone Night Answer
The relay contacts for the station ringer interface follows the ring pattern of a ringing line or
telephone. These relay contacts close during ringing and open between rings and may be used to
control an external signaling device. The relay contacts for the paging enable and door relay are
closed while the activating station is off-hook and may be used to provide a path for an enabling
signal where needed. Contacts on relay 1 is normally closed when idle and contacts on relays 2, 3,
and 4 are normally open when idle.

Flexible Ringing Assignments, Line Answer From Any Station, and Night Transfer (Of Ringing).
