Nortel Networks 311 Call routing to RAN trunks, Programming RAN trunks

Operation 675

In the pulse start mode, a start pulse activates playback of a message that

continues until completion. The announcement machine ignores all other

start pulses that might occur until the message is complete.

In the level start mode, the start signal is a "level" rather than a pulse. The

leading edge of the start signal initiates message playback that continues

until either the trailing edge of the start signal occurs or the end of the

message is reached. A message that is terminated by the trailing edge of a

level start signal is immediately reset and ready for playback again.

Call routing to RAN trunks

The CS 1000 software controls recorded announcement machines. These

programs detect the calls to be intercepted, determine the type of intercept

treatment required (for example,overﬂow, attendant, announcement), queue

the intercept, and provide ringback tone to the calling party. At the proper

time, an intercepted call is connected to the appropriate RAN trunk.

Programming RAN trunks

The type of intercept and the RAN trunk parameters are deﬁned in the

TrunkData Block LD 14, Customer Data Block LD 15, and Route Data

Block LD 16 programs.

The TrunkData Block and Route Data Block programs specify the following:

•the RAN trunk

•the type of announcement machine

•the number of repetitions of announcements before a forceddisconnect

(all calls) or an attendant intercept is initiated (CCSA/DID calls only)

•the point at which the trunk may be connected to the announcement

The Customer Data Block program deﬁnes the type of intercept and the

trunk route to which the intercept is to be connected.
