D-114 Delay Announcement - Attendant
D-114 Delay Announcement - Attendant
General Description
This feature provides a recorded announcement to the incoming trunk caller waiting to be answered by the
Attendant. This feature is divided into the following two types, depending on the time when the call is connected
with the announcement trunk.
• The call is connected to announcement trunk immediately after terminating to the Attendant Console. The
announcement continues until the Attendant answers, or the trunk side abandons the call.
• The call is connected to the announcement trunk after the ringback tone connection.
Operating Procedure
When the announcement service is provided immediately after the call terminates
1. When an incoming call terminates to an Attendant Console, which is handling calls, the calling party
receives an announcement from the Digital Announcement Trunk (DAT).
2. When the Attendant completes call handling, ringing starts at the Attendant Console.
3. The Attendant presses the ANSWER key. The calling party and the Attendant talk with each other.
When the announcement service is provided after a fixed time
1. When an incoming call terminates to an Attendant Console, the LDN key lamp starts to flash and ringing
starts at the Attendant Console, and the calling party receives the ringback tone.
2. When the Attendant has not answered for the designated time (SYS1, Index 242), the call is connected to
the announcement trunk automatically (the lamp keeps flashing and the ringing continues at the Attendant
Console).
3. If the Attendant does not answer the call when the first announcement completes, the trunk call
disconnects from the announcement automatically and the caller hears the music on hold.
4. The Attendant presses the ANSWER or LDN key. The calling party and the Attendant talk with each
other.
