Upon connection, the A3LA-R reports the DTE speed (default) 

1

 

Upon connection, the A3LA-R reports the  line speed, the error correction protocol 
and the DTE speed in that order 

2

 

Upon connection, the A3LA-R reports its data port speed 

A.8.9   Zn – Soft Reset

A.8.10  &Cn – DCD Option 

Select how the A3LA-R controls the DCD behavior. 

0

 

DCD is forced on at all times 

1

 

DCD indicates the connection status (default) 

A.8.11  &Dn – DTR Option 

Set the A3LA-R reaction to DTR signal. 

0  

DTR is ignored in all modes. A DTR signal input is not needed when set to &D0. 

For all other &Dn settings, the following applies.  

DTR must be ON during on-hook command mode. If DTR transitions from ON to OFF during on-
hook  command  mode,  operation  will  be  locked  after  approximately  10  seconds.  On-hook 
command mode operation will resume when DTR is restored ON.  

DTR must be ON at call connection 

DTR must be ON during both in-call command mode and in-call data mode. Reaction to DTR ON 

to  OFF  transitions  during  in-call  command  mode  and  in-call  data  mode  is  determined  by  the 
&Dn  setting  as  shown  below. 

Note  that  the  +CVHU  command  can  be  set  to  override  these 

specified reactions.

  

1  

If  DTR  transitions  from  ON  to  OFF  during  in-call  command  mode,  and  DTR  is 

restored ON within approximately 10 seconds, the call will remain up. If DTR is not 
restored  ON  within  approximately  10  seconds,  the  call  will  drop  to  on-hook 
command mode. 
If DTR transitions from ON to OFF during in-call data mode, the mode will change 

to in-call command mode. If DTR is restored ON within approximately 10 seconds, 
the call will remain up. If DTR is not restored ON within approximately 10 seconds, 
the call will drop to on-hook command mode.
