Call routing to RAN trunks
CS 1000 Release 4.0 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 Trunk
Data Block LD 14, Customer Data Block LD 15, and Route Data Block
LD 16 programs.
The Trunk Data 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 forced disconnect
(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.
Refer to Software Input/Output: Administration (553-3001-311) for
