t320 – Timer delay ISDN disconnect
Delay time between the clear message of the last X.25 connection and an automatic 
ISDN disconnect. Only valid for X.25 B channel.

0: 

immediate ISDN disconnect (default)

1..n:  delay time in seconds (1..254).

255:  immediate ISDN disconnect

Note:  The released X.25 connection will be signalled due to the selected mode  

(via response “NO CARRIER”, CLR xxx or DCD goes inactive). The  unreleased 
ISDN connection is not signalled, also the released ISDN connection has no signal.

v110llc – Usage of LLC for V.110 connections
If set the LLC parameter will be used for incoming and outgoing V.110 connections.

0:   LLC is ignored and not created 

1:    Ougoing call: An LLC is sent deriving from the settings of the  

TA incoming call: The received LLC is used to setup the  
parameters for the V.110 connection. (default).

v110flc – Usage of V.110 flowcontrol

0: 

V.110 flowcontrol via xbits will be ignored. (default).

1: 

V.110 flowcontrol via xbits enabled 

*wbrk – break and data packing

0:  

 Break and data packing disabled. Break detected on the DTE side ignored. 
(default)

1-255:   Break and data packing enabled . When a break is detected on the local  

DTE side the modem will send a break to the remote side.  
The length of the break is set in increments of 10ms according to this 
parameter (10 – 2550 ms). The parameter set the break length at the  
local modem.

When the “Break and data packing” is enabled data are packaged in frames before being 
transferred between the modems. Packing of data in frames enables the possibility to 
transfer break signals over the line independent of line protocol but will lower the 
transferee rate slightly. With that in mind the “Break and data packing” shall only be used 
when break handling over the line is necessary. 
Note! Modem in both ends must have the *wbrk enabled but doesn’t need to have the 
same parameter value.
