553-3001-306 Standard 10.00 January 2002
On M3000 telephones, the CCOS key can be assigned as a programmable key
(0-5 only).
This feature is applicable only when the CLS lamp is lit on the controlling
telephone.
The CLS key on an Attendant Console can be used only on an idle loop. (The
loop lamp is lit; source and destination lamps are dark.)
Feature interactions
Attendant Administration
This feature cannot change Controlled Class Service restrictions (CCRS),
ECC1 or ECC2, but can assign CLS keys to certain telephones.
Attendant Supervisory Console
When the attendant is in the supervisory mode, CCOS programming is
prohibited.
Authorization Codes
The Authorization Code can override a telephone’s CCOS restriction level.
Conference
If CCOS is activated at a telephone on a conference call, established Public
Exchange/Central Office or toll calls are not affected. The CCOS restriction
level is applied immediately; however, no new calls can be initiated from the
conference. That telephone remains in the CCOS state after the end of the
conference.
Coordinated Dialing Plan
The internal DN is used for programming the CLS level for Coordinated
Dialing Plan (CDP) from the controlling telephone.
Multiple Appearance Directory Number
All CCOS restriction levels are activated and canceled from the Prime
Directory Number (PDN) for CCOS controlling telephones. The PDN for an
SL-1 telephone is made CCOS active, and all DNs for that telephone are
restricted as well. If that DN is a PDN on other telephones, they are also
restricted (if they have CCSA Class of Service).
