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.

These programs detect the calls to be intercepted, determine the type of
intercept treatment required (overflow, attendant, announcement, etc.),
queue the intercept, and provide ringback tone to the calling party. At the

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.
