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...

(2) Key Operations on the Desk Console (DESKCON)
By the operations on the Desk Console, restriction is applied 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.
