Line Load Control

In the Telephony Server system, Line Load Control can be activated automatically or manually as a
countermeasure against abnormal traffic congestion towards the stations accommodated in the PIR.
In the case of automatic control, the system automatically monitors an overloaded situation and restricts
outgoing calls from stations and incoming calls from trunks.
In the case of manual control, the operator at an Attendant/Desk Console or PCPro 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 PCPro
•
System automatic monitoring
5.3.1 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 the ASFC command is set as RES=0 (incoming calls to that
station are allowed). For restricting incoming calls from a trunk, system data ASYD, SYS 1, INDEX 59,
b0=1 should be assigned.
