358 Camp-On, Forced
Forced Camp-On is similar to station-to-station Camp-On except that
Forced Camp-On can be done with either no call on hold or an external or
internal call on hold. It can be done automatically or manually; whether it is
automatic or manual is determined by the response to the Automatic Forced
Camp-On (AFCO) prompt in LD 15.
For manual operation, once a busy telephone has been reached, the first
depression of the EOVR key or the first dialing of the EOVR FFC attempts
Forced Camp-On. If successful, Forced Camp-On introduces Camp-On
tone into the connection. If unsuccessful, overflow (fast busy) tone is
returned to the party attempting the Forced Camp-On.
For Forced Camp-On to be attempted, all other methods of call termination
must have been tried, the last of which was Camp-On. If station-to-station
Camp-On or automatic Forced Camp-On has occurred, or Forced Camp-On
has been excluded by the new telephone options, then the first depression
of the EOVR key or dialing of the EOVR FFC executes Enhanced Override.
If, however, Forced Camp-On is denied due to existing Camp-On limitations,
Enhanced Override is also denied.
Operating parameters
The Flexible Feature Codes (FFC) package (139) must be equipped
for Forced Camp-On and Priority Override to be available from analog
(500/2500 type) telephones.
For analog (500/2500 type) telephone activation, the Multi-Party Operations
(MPO) package (141) must be equipped, with "YES" as the response to the
RALL prompt in LD 15 to ensure register recalls are required before dialing
control digits. The EOVF FFC defined must not start with the same digit as
one of the control digits. The control digits are defined in LD 15 and are
printed as part of the Customer Data Block (LD 21).
Telephones or trunks involved in any of the following cannot be camped
