D/228/1
the current packet to be forwarded. If set to zero, there
is no timed forwarding.
%L10 (Line Folding)
Range
0 to 255 0
Default
Description
Specifies the line length required. When the specified
number of characters have been sent to the DTE a
carriage return and line feed are sent to ensure that lines
do not exceed the required length. A value of zero
disables line folding.
Note:
If %L3 and %L4 are both 0, characters will be forwarded as they become available.
1.5.6.2.5 B Channel LAPB Parameters
All !B registers can be viewed using the !Bn command.
!B1 (LAPB T1 Timer)
Range
1 to 255 3
Default
Description
Sets the value, in seconds, of the LAPB T1 timer.
!B2 (LAPB T3 Timer)
Range
1 to 255 15
Default
Description
Sets the value, in seconds, of the LAPB T3 timer.
!B3 (LAPB N2 Retry Count)
Range
1 to 255 4
Default
Description
Sets the number of times the LAPB protocol will retry
sending before giving up and applying recovery
procedures.
!B5 (Active/Passive)
Value
0 (default)
1
Description
X.25 is Active ie initiates link initialisation.
X.25 is Passive and waits for the network to initialise the link.
1.5.6.2.6 Basic Configuration Parameters
!C4 (B1 Channel Mapping)
Enables data calls to be made and accepted on the B1-channel. If !C5 is set to 0 the outgoing call
SETUP message will contain a Channel Identification Information Element set to B1-channel only.
Value
0
Description
Incoming data calls on the B1-channel are rejected with ‘channel not
acceptable’ as the cause.
Incoming data calls on the B1-channel are accepted provided no other
data call is present.
4 (default)
!C5 (B2 Channel Mapping)
Enables data calls to be made and accepted on the B2-channel. If !C4 is set to 0 the outgoing call
SETUP message will contain a Channel Identification Information Element set to B2-channel only.
