| Eric,
I'm not familiar with this particular modem, but I'll have a go at
helping you here.
Easy one first:
> Can I configur the Modem from the RA EW's consol? or no way?
If your modem uses the asynchronous AT command set (which most modems
I've come across use) then no, you have to plug your terminal (or
whatever you use as console input) to the modem directly, in
asynchronous mode.
The Hayes ULTRA 144 doesn't seem to be mentioned in
routeabout.zko.dec.com/WAN/v25bis/v25bis.htm, so can I take it that
you've set the modem up as described in the general directions of
section 5.0 of that document?
You need to have set the router up correctly for v25bis dialling - look
in http://routeabout.zko.dec.com/~guisso/books/niog/ch11v5cm.htm for
details.
To get the modem to dial, you would need to have, for example, IP
configured on the dial circuit interface. Then RIP updates arriving at
the dial circuit will start the dialup process. Alternatively if you
are using the dialup as a backup (e.g with WAN Restoral) the failure of
the primary link should start the dialup.
If you think your configuration is OK after doing these checks, please
turn on some events in the router event logger. These ones are useful:
ELS config>disp sub v25b all
ELS config>disp sub sl all
ELS config>disp eve gw.43
If you then look at the events using the
*T 2
command, if everything is working ok, you should see, amoungst others,
something like:
V25B.025: Clnt CR 1111 nt 2 int V25/0
...
V25B.033: FSM st changing to 6+12: V25B Connected, on net 2 int V25/0
After that you should see data exchange.
As for the modem lights, if TR and MR are on, it suggests that the router has
asserted Terminal Ready, and is trying to dial, so your configuration
should be nearly right.
If you still have problems, please post your configuration for V.25 bis
and your dial circuit here, together with the events stream you see
with the above event configuration, and I'll take another look

| Brian,
Sorry for this so late respond, I had a long trip and can not do the test.
Now I am back, and do the test again step by step following the "v25bis.htm",
and turn on the event logger you said. Please help me to solve it:

mentioned in the "v25bis.htm" file)

the first ethernet port use as LAN port.

For the Modem, I setup it following the "v25bis.htm" 5.3.1 "Modem
Configuration".
Then, turn on the Modem power with the router attached cable and dial line, on
the modem panel, "SD" and "28.8" always on, "CD" and "TR" do cycle flash.
The event log:

| Eric,
As Tim says, check your image revision number. But apart from that,
it looks to me as if the V.25 bis interface is failing selftest because
the modem signals aren't being seen as "ON":
>SL.007: st slftst nt 2 int V.25/0
>SL.021: slf tst fl bcs of mdm sts, CTS = OFF, DSR = OFF, DCD = OFF, nt
2 int
With many modems, these signals can be forced to the "ON" condition, so
you could try that and see if the SL.021 event shows them in the "ON"
state. The AT commands (I think) are:
AT&C0 for DCD
AT&R1 for CTS
AT&S0 for DSR
Another way to find out is to go into the V.25 bis monitor:
*t 5
+n 2
V.25bis Console
V.25bis> stat
This gives you a display of (amoung other things) what's happening on
the interface - you should be able to see the states of the modem
controls from here.
Let us know what you find!
Brian
