•
The circled numerals indicate the call restriction functions. (See the table at right.)
•
The arrows indicate the flow directions of sent signals.
•
The signals can be received even under call
restrictions.
Impose restriction on a port to prevent origination from a specific line among
several lines connected. -- The line becomes for reception only
Restrict transmission from ISDN to G4 mode only.
Always impose call restriction on an NCU or ICM port where no line is
connected.--This setting is necessary only for NCU and ICM installed.
No ISDN line when ICM is attached -> Restrict 12 and
13. ("G4 fault" is displayed at G4 read.)
Use one of several communication modules for reception only.
Restricting 14 (Disabling G3 transmission and speech
from ISDN)
No origination from outside line 1 when NCU0 and ICM
are attached (Setting the line to receive-only) -> Restrict
2.
Setting G3M1 to receive-only -> Restrict 4.
