NEC NDA-24300 manual Line Load Control, Operating Procedure

SYSTEM OPERATIONS

4.LINE LOAD CONTROL

In the PBX, Line Load Control can be activated automatically or manually as a countermeasure against abnor- mal traffic congestion.

In the case of automatic control, the system automatically monitors an overloaded situation and restricts out- going calls from stations and incoming calls from trunks.

In the case of manual control, the operator at an Attendant/Desk Console or the MAT restricts outgoing calls from stations and incoming calls from trunks.

This section covers the following methods to activate Line Load Control:

•Control by dialing an access code from the ATTCON/DESKCON

•Control by entering command data from the MAT

•System automatic monitoring

Operating Procedure

For restricting incoming calls from a trunk, system data ASYD, SYS1, INDEX59, b0=1 should be assigned.
