Strata CIX General Description 08/14 167
Line Buttons
Telephone buttons that are used for making and receiving outside calls are referred to as Line (or
CO Line) buttons. (For information on various [DN] buttons, refer to “Directory Numbers” on
page 143.) The Strata CIX supports the following types of line buttons:
CO Line Buttons
System Availability: All systems
Smaller systems have traditionally provided the direct appearance of the CO lines on the
telephones where maximum visibility of the line status, flexible ringing assignments, and informal
call transfers associated with key telephone systems may be implemented.
Pooled CO Line Button
System Availability: All systems
Pooled Line Group buttons enable a group of CO lines to “appear” under one button. Pooled and
single appearing line buttons are designed for use with loop and ground start lines, not Tie, DID,
DNIS or ANI lines.
Group CO Line Button
System Availability: All systems
Group CO line buttons are like individual CO line buttons except these buttons represent all the
lines for a particular ISDN Channel Group. This enables ISDN channels to operate similar to
analog CO lines on a key telephone system. These buttons may have appearances on multiple
telephones providing call coverage across several telephones. Multiple appearances of the same
Group CO line button is possible on each phone to allow multiple call handling for that group from
each station.
Live System Programming
System Availability: All systems
Programming the Strata CIX from an on-site or off-site location does not interrupt the operation of
the system in most cases. It is interrupted for hardware upgrades.
Lost Call Treatment
System Availability: All systems
Lost Call Treatment provides the CIX a mechanism for terminating calls that cannot be terminated
with the usual calling patterns. One scenario would be a call that is recalled to a station, the station
user is no longer there to answer the recall and no forwarding pattern is programmed. The call will
ring at the recalled station until the Lost Call Timer has expired after which the system will direct
the call to the Lost Call Destination.
