Day/Night
Description
The system provides eight COSs for assignment of outside line dialing privileges. Each
system station may be assigned one Day COS and one Night COS. The station COS is
primarily used for restriction and control of long distance dialing. Toll restriction tables
allow customized dialing privileges to be assigned to any or all COSs. This COS is directly
referenced in the Restriction, CO Line Call Discrimination, Digit Interval Table
programming. System Speed Dial is specially linked with COS such that all speed dial bins
override toll restriction programming in the toll restriction tables. It should be noted that
stations assigned COS (0-5) have access to all System Speed Dial Bins (20-99). Stations
assigned COS 6 can only access System Speed Dial Bins (20-39). Stations assigned COS 7
have no access to System Speed Dial. COS affects the station override of DND where a
station with a lower level COS can be overridden by a station with a higher level of COS.
For instance, an extension with COS 0 may override a station with COS 1. COS also affects
the operation of Privacy Release. Stations with equal or greater levels of COS may join a
busy CO line conversation when Privacy Release is enabled. For example, a station
assigned COS 1 may join a CO line conversation with a station assigned COS 1 or lower.
Operation
Station COS is assigned in system programming and is not a feature that requires specific
operating instructions. A station's COS will determine what digit sequences may be
dialed on CO lines.
CO Line Group Assignment
Description
The system provides four CO Line Groups for assignment of specific CO lines. The CO Line
Group assignment is used for CO Line Pool access. The CO Line Groups are designated by
2-digit notation when programmed on station programmable feature buttons. CO Line
Group 1 is programmed by dialing [01], CO Line Group 2 is programmed by dialing [02],
etc. An All CO Line Group code is available for programmable feature button assignment
by dialing [00] for that feature button. At default, all CO Lines are assigned to Group 1.
The highest level COS is 0 (the most dialing priviledge) and the lowest COS level (least dialing
priviledge) is 7.
