916.0. "v25bis and backup trouble for EW" by NNTPD::"[email protected]" (Ellen Syberg) Mon May 26 1997 11:16

A customer has trouble configurating WAN restoral, and thats why I have 
set up a test.That is not working either. 

The Modem is a Microcom DeskPorte FAST + and the switches is set up for 
synchronous operation as described in the manual. 

Both of the RouteAbouts EW has been upgraded to ver. 2-03.
They both have been set up to bridging and NOT routing. Is that posible ? 
To set up a backup circuit for bridging ? 

I see absolutely nothing in the event logger on BONDO after  
els config>disp sub v25b all
els config>disp sub s1 all
els config>disp sub gw.43 all
and * T 2
and after I have taken down the primary circuit. Shouldn't I even though
I have only been able to get hold on one modem in the test ?

What am I doing wrong ??
Any help to get me going would be very much appreciated.

916.1A couple of things to try ...MARVIN::CROWLESeek not answers; live the questionsTue May 27 1997 06:2734
    Hi Ellen,
    
    > They both have been set up to bridging and NOT routing. Is that
    posible ?
    > To set up a backup circuit for bridging ?
    
    Should be OK, we have done some testing with bridging.  I'm not
    familiar with TCP/IP-Host Services configuration - someone else
    might like to comment on that, But I think you have a more basic
    problem if your modem won't dial when you take the primary down.
    
    Y ou should be able to get the outgoing modem to at least dial
    properly, even though there is nothing connected remotely.
    
    Looking at your device config for BONDO, unless I've missed something,
    you don't show the step:
    
    V.25bis Config> set local
    Local network address name   []? BONDO
    
    although this may not be your problem.
    
    Could you please set up, in your event logger:
    
    els config>disp sub wrs all
    
    in addition to the other ones you mention, and then try again to bring
    the primary down whilst you have the events displayed with *T 2.  If
    you can then post the event log here (or mail it to me if you like) I
    will try to find out why you aren't getting your modem to dial.
    
    Good luck!

Brian, 

The same result as in 840.4 
>it looks to me as if the V.25 bis interface is failing selftest because

I have tried to set up the modem as descripted in 
http://routeabout.zko.dec.com/WAN/v25bis/v25bis.htm page 11 and 12.
I set the switches with no. 4 up and enter the following command 
-ATY0@B1&S1\D4:T15=155%G1%B28800M0*W
but when I hit return the terminal window shows
-ERROR
or -ATY0@B1&S1\D4:T15=155%G1%B28800M0&W-ERROR
When I do every single command in turn it shows that almost all the command
shows errors. ATY0-OK, AT&S1-OK, AT\D4-ERROR, AT:T15=155-ERROR, AT%G1-ERROR, 
AT%B28800-ERROR, ATM0-OK 
I have tried it several times, cleared the config AT&F turned 
the modem off and then on again, but still the same.
I appriciate your help 
/Ellen

    I'm guessing you have to enter that whole AT string at once, because
    some part of it may switch you to V.25bis mode, sync operation, etc...
    
    Are you carefully following the other directions for that modem (the
    switch pack settings before and after the AT command)?  Are you sure
    you've got a "Microcom - Deskporte FAST with V.34"?  Some manufacturers
    have similar models with and without V.25bis.
916.4Firmware of the modem is prob. outdatedNNTPD::"[email protected]"Ellen SybergWed May 28 1997 11:3313
Thanks a lot for your reply, you gave me the right hint.
The modem Microcom DeskPorte FAST + does support v25bis syncronous etc.,
but it is only the name of the modem and the manuals that support 
V.34 standard and probally not the firmware in the modem. 
The last page of the manual tells me how to get ITU-T Upgrade. The modem 
is upgradeble from the V.fast protocol to the V.34 standard it says. 
I suppose that's what's wrong because I have the manual, all the AT commands 
are mentioned in it, and I did try the AT command in one string.
Thanks Ellen
