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
(1) Operations on the Attendant Console
By the operations on the ATTCON, restriction is effected on an outgoing call from a station having SFC
in which the SFI = 16 (Line Load Control) of ASFC command is set as RES=0 (incoming calls to that
station are allowed). For restricting incoming calls from a trunk, system data ASYD, SYS1, INDEX59,
b0=1 should be assigned.
