546 Collect Call Blocking
For data calls, all calls is answered with the CCB answer signal, if CCB is
enabled. This may have an effect on data protocols, while CCB signaling
is taking place.
If firmware timing is used (FWTM = YES in Overlay14) for sending the
CCB flash, the CCB2 timer is downloaded to the card before sending the
firmware flash. If the CCB2 timer is changed in the Route Data Block, either
the card has to be enabled or the switch has to be initialized to get the new
CCB2 timer downloaded to the card.
Feature interactions

Automatic Answerback

The Automatic Answerback (AAB) feature, when assigned to a Meridian 1
proprietary telephone, allows any incoming call to a single-appearance
Prime Directory Number (PDN) to be answered automatically. If an
incoming DID or CO call terminates on a set with the AAB feature enabled,
the call is automatically answered after one ring. If the set has a CCBA
Class of Service, the CCB answer signal is provided in the place of the
regular answer signal.
Automatic Call Distribution
Collect Call Blocking can be enabled on an ACD queue basis. Hence, if
an incoming CO or DID call is answered by an ACD agent, the answer
supervision signal that is returned to the CO is determined by the value of
the CCBA prompt in LD 23. While the CCB answer signal is being sent, the
same limitations apply to ACD as apply to sets with CCBA Class of Service.

Automatic Call Distribution Interflow

If an ACD call from a route with CCB enabled is diverted to an interflow DN,
and answer supervision has not already been provided, the answer signal
returned to the CO depends on the source ACD queue. The CCB answer
signal is returned to the CO if the source ACD queue has CCB enabled.

Automatic Call Distribution Night Call Forward

During Night Call Forward (ACD) call processing, the source ACD queue is
removed or overwritten. Therefore, the CCB treatment given is based on
the queue the call happens to be in at the time the call is answered.

Automatic Call Distribution Night RAN Route Announcement

If an ACD call from a route with CCB enabled is diverted to a Night RAN
route (defined by NRRT in the ACD block), the CCB signal returned to the
CO depends on the source ACD queue. If the source ACD queue has CCB
enabled, the CCB answer signal is sent to the CO.
