596 Controlled Class of Service
Feature interactions

Authorization Code

The Authorization Code overrides a telephone’s CCOS restriction level.
Conference
If CCOS is activated at a telephone involved in a conference call, established
Central Office or toll calls are not affected. The CCOS restriction level is
applied immediately, and no new calls can be initiated from the conference.
The telephone remains in the CCOS active state after the conference is
terminated.
Flexible Feature Codes
If Electronic Lock (ELK) is activated, the CCRS Class of Service is used
whether Controlled Class of Service (CCOS) is active or not. ELK takes
precedence over CCOS. If ELK is deactivated, the set is treated as per
existing operation.
When FFC ELKA and a password is entered, this set will use the CCRS
Class of Service configured in LD 15. The CCRS Class of Service will
always be used whether or not CCOS is currently controlling the set’s
Class of Service. When FFC ELKD and a password is entered, the set will
use the appropriate Class of Service associated with this set. If CCOS is
enabled for the set, the associated customer Class of Service is used (that
is, CCRS, ECC1, or ECC2). If CCOS is not enabled for this set, the set’s
own Class of Service is used.
When FFC ELK is deactivated, the set reverts back to the Class of Service
as it should be without FFC ELK, instead of always reverting back to the set’s
Class of Service (that is, if CCOS is enabled, it will use the customer’s Class
of Service; if CCOS is not enabled, it will use the set’s Class of Service).
Hot Line
When a Hot Line DN is on a telephone that has Controlled Class of Service
activated, Hot Line calls ignore the imposed Class of Service if the System
Speed Call (SSC) package is present and the Hot Line list is given an
adequate Network Class of Service (NCOS) for the override

Multiple Appearance Directory Number

CCOS restriction levels are activated or canceled on controlled telephones
through their Prime Directory Number (PDN). When the PDN of a Meridian
1 proprietary telephone is made CCOS active, all DNs on that telephone are
also restricted. If the DN is a PDN on other telephones, those telephones
are also restricted (if they have CCSA Class of Service).
