General Description
This service feature routes Listed Directory Number (LDN) calls from both ISDN/non-ISDN network to a
preselected station within the system, when the Night mode has been entered.
Operating Procedure
To answer LDN NIGHT CONNECTION calls
1. An incoming LDN call in Night mode is automatically routed to a preselected LDN NIGHT
CONNECTION station within the system.
2. The calling party receives ringback tone.
3. The ringing signal is sent to the LDN NIGHT CONNECTION station.
4. The LDN NIGHT CONNECTION station goes off-hook to answer the incoming call. If necessary, this
station can transfer the incoming call to another station within the system using the CALL TRANSFER -
ALL CALLS [C-11] service.
Service Conditions
