C-15 Class Of Service - Individual
C-15 Class Of Service - Individual
General Description
This feature permits all NEAX2400 IPX stations to be assigned a Class of Service in accordance with the degree of
system use desired. Each station is assigned one class from each of three groups.
Operating Procedure
CLASS OF SERVICE - INDIVIDUAL is assigned via system data entry. Thereafter, each station is automatically
provided with the desired degree of service.
Service Conditions
1. The CLASS OF SERVICE - INDIVIDUAL feature in the NEAX2400 IPX contains three categories:
Telephone Equipment Class (TEC), Service Feature Class (SFC), and Route Service Class (RSC).
2. TEC determines the type of terminal and the signalling arrangement necessary.
3. Trunk Route Restriction Class provides 15 groups. Separate restriction patterns for each group are
programmed in system data. Group RSC0 is reserved for ATTENDANT CONSOLE use only.
4. Fifteen types of Service Feature Classes are available for access to the following special service features.
These classes are assigned to each station in order to determine which features a particular station will be
permitted to use.
ATTENDANT CAMP-ON WITH TONE INDICATION [A-1]
CALL BACK [C-1]
CALL FORWARDING [C-2, C-3, C-5]
CALL HOLD [C-6]
DATA LINE SECURITY [D-12]
EXECUTIVE RIGHT-OF-WAY [E-1]
OUTGOING TRUNK QUEUING [O-2]
SMDR [S-10]
SPEED CALLING - SYSTEM [S-3]
TRUNK ANSWER FROM ANY STATION (TAS) [T-8]
For details, refer to the NEAX2400 IPX Office Data Specification.
5. Stations may be programmed to change SFC and RSC when the Attendant has set NIGHT CONNECTION
[N-1, 2]. This is accomplished via system data entry. For further information, refer to DAY/NIGHT
CLASS OF SERVICE
[D-15] .
6. TEC, RSC, and SFC are independent, with no interaction between them.
7. RSC and SFC can be assigned independently on a TENANT [T-12] basis.
8. The system software is capable of eliminating 5dB loss on station-to-station calls on a per-station basis.
9. The system software is capable of eliminating DISTINCTIVE RINGING [D-10] on a per-station basis (for
OPX stations).
10. RSC can be overridden by a new RSC, using the AUTHORIZATION CODE [A-20] feature.
Interactions
The following features interact with the fully restricted station
1. CALL TRANSFER - ALL CALLS [C-11]: A fully restricted station can be transferred to a station or the
Attendant by another party using the CALL TRANSFER - ALL CALLS [C-11] feature. The fully
restricted station may transfer a station-to-station call to a station or the Attendant.
