[comp.dcom.modems] Problem getting Hayes V-Series Smartmodem 9600 to connect to T2500

dag@fciva.FRANKLIN.COM (Daniel A. Graifer) (01/03/91)

I have an Hayes V-Series Smartmodem 9600 modem connected to my Mac.  I can
talk to the modem just fine.  I want to call our unix host in v32/v42 mode.
The host has a Telebit T2500, which will operate at v32/9600bps.  When I call,
t
the modem grabs the second tone sequence presented, then immediately reports
'NO CARRIER'.  I've tried everything I can think of.  My Hayes configuration is:

B1 E1 L2 M1 N0 Q0 T V1 W1 X4 Y0 &C1 &D2 &G0 &J0 &K3 &L0 &P0 &Q0 &R0 &S0 &T4 &X0

S46:002 S48:007 S49:008 S50:016

The standby configuration of the T2500 is:

OK

In particular, the combination of S50=0 and S92=1 should mean the tone
presentation sequence is v.25,v.32,...

I've been trying for several nights now.  I'm posting this stuff at 2400bps.
What a waste of two fine modems!  Anybody got any ideas?  (I must admit I'm
really hoping Toby Nixon will find time to answer this!)

Many, Many thanks in advance....

The V-series Smartmodem 9600 uses a proprietary, non-standard 
fast-turnaround ping-pong modulation scheme above 2400bps.  Although 
some aspects of this modulation are LIKE V.32 (it uses trellis 
coding and a similar constellation), it is NOT compliant with CCITT 
V.32 and will NOT communicate with anything but another Hayes modem 
above 2400bps.  This is similar to the situation that exists with 
the Telebit Trailblazer Plus -- standard up to 2400, but proprietary 
above 2400.  

The Hayes Ultra 96 (V-series ULTRA Smartmodem 9600) supports _real_ 
compliant V.32 at 4800 and 9600.  It connects just fine with the 
T1500 and T2500, as well as previous VSM9600s.  This is similar in 
philosophy to the T2500 -- the Ultra 96 supports both the standard 
V.32 modulation _and_ Hayes' proprietary ping-pong modulation at 
9600.

You shouldn't get a "NO CARRIER" when calling a T2500 with a 
VSM9600; they should in fact connect at 2400bps, which is the 
highest speed they have in common.

The V-Series Smartmodem 9600 is =not= a V.32 modem!!!

You will not be able to connect at 9600 bps with a V.32 modem. The only
V-Series modem that features V.32 modulation is the Ultra.

You didn't say whether the Hayes was an ULTRA or not.  If it isn't, its v.32
is a half-duplex proprietary protocol that will only connect with another
Hayes at 9600 baud.  The fastest speed it has in common with the Telebit IS
2400.  The ULTRA, on the other hand should connect at 9600 without problems.

Mike an Maurice are only half right.  The ULTRA is not the only Hayes V.32
modem.  Hayes has manufactured four 9600 baud modems to my knowledge, I have
owned three of them.  The first is called the Hayes V-Series 9600, I am
guessing this is what you have, it uses a proprietary half-duplex ping-pong
protocol to simulate full-duplex, it will only work with other V-series
modems.  The second modem is called the Hayes 9600 V.42, it also uses the
V-series protocol (so you can talk to one of these) and it adds V.42 error
checking to insure data transmission, latter MNP-4 was added to comply with
the V.42 standard (NOTE: V.42 is an error checking protocol and not a
standard, the Hayes 9600 V.42 can not talk to other V.42 modems unless they
also support the V-series protocol, which none other than Hayes do).  The
third is called the Hayes Smartmodem V.32, it is a full duplex V.32 modem,
it has a 4 line LCD display as well as soft menu buttons, so you can
configure any of the modems options via the LCD and buttons (very handy in
synchronous operation), or via the standard Hayes command set.  This modem
can also operate in a leased line environment.  The SmartModem V.32 has no
error checking, and there are no plans to add any.  The last is the Hayes
ULTRA which supports V.32, and V.42bis.  The Smartmodem is a more expensive
modem than the Ultra.  If anyone needs one for use on a leased line or
in a synchronous environment, please let me know!  I have a brand new one I
will gladly trade for the less expensive ULTRA or comparable modem.

If it turns out that you do have the Smartmodem V.32 or the ULTRA then you
should be able to talk with other V.32 modems, otherwise you have an
expensive 2400 baud modem (if its the V.42 at least you have some nice
error checking ;-)  ).

Did I get this pretty right, Tony?  Want to buy a SmartModem V.32  :-)

I seem to be having the same problem too with my Hayes Ultra 9600 modem.
When I dial up to my unix host, (which has a Telebit TrailBlazer) a connection
is made, but is quickly lost; the message 'NO CARRIER' is displayed.
My modem is connected to a NeXT cube. Is there anyone out there that has a 
simple answer to this problem?


Thank You,
Sal Cataudella

The Hayes V-Series Smartmodem 9600 does not support CCITT V.32 9600, but
instead uses "Hayes Ping Pong" modulation at 9600bps. The Hayes V-Series ULTRA
Smartmodem 9600, or ULTRA 96, does support CCITT V. For additional
information, you can contact the Hayes Support BBS at 1-800-US-HAYES. A
pamphlet entitled "FAST ANSWERS about fast modems" explains the differences
between their three 9600bps models.

We have Hayes V-Series Smartmodem 9600 modems here - and ours don't
support V.32 or v.42bis - only V.42 which is something different.

We can't connect with a T2500 modem at speeds above 2400 baud..

I had a simular problem with a Hayes Smartmodem 2400.  I think the problem is
that by the time the T2500 gets through the PEP tones and the answer tone, the
Hayes has timed out.  I solved the problem by setting S9=30 and S10=50.  
Something less might be OK, but this works.  Make sure that S7 is not less
than 30.  S10 must be greater than S9 because the actual loss of carrier
that can be tolerated is the difference between S10 and S9.  

Since I have done this I get 100% connection.

CCITT V.42 _is_ the international standard for modem error control!  
A Hayes V-series Smartmodem 9600 V.42 will connect in error-control 
mode with Bell 212, V.22, or V.22bis modulation with any other 
similarly-equipmented modem (V.42 or MNP4).  It won't connect at 
9600 with any but another Hayes V-series 9600 modem.  The ULTRA 96 
_will_ connect at 9600 with V.42 error control with modems from 
other manufacturers using V.32 modulation.

When you first posted your message to this regard, I tried to reply 
to you but the message got rejected somewhere along the way -- so 
I'm posting this reply on the net.  If your Smartmodem 9600 is 
"brand new", please contact Barbara Miller, manager of customer 
service at Hayes (404-449-8791), to see about arranging a trade for 
an Ultra 96.

> Did I get this pretty right, Tony?  Want to buy a SmartModem V.32  :-)

Yes, you got it real close, except as I noted above.  I must also 
point out that it is possible to upgrade an original V-series 
Smartmodem 9600 to V.42bis capability with a simple ROM upgrade; all 
you have to do is call Hayes Technical Support to arrange it 
(404-441-1617).  It can't be upgraded to V.32 modulation, however.

Thanks to all of you that responded.  What I have is the Hayes Smartmodem
Series 9600 V.42, which will only talk to other Hayes Modems above 2400bps.
The reason I got "NO CARRIER" is that I had the register set that says ONLY
connect at the DTE line speed.  ( Set this trying to force a connection >
2400bps).

   You're right, of course, but Jason's message needs translation:

What Jason Said                 What Jason Meant

"V.42 is ... not a standard"    V.42 does not define a modulation protocol

"The Hayes 9600 V.42 can not    Hayes' V-9600 will only speak at 9600+ bps
talk to other V.42 modems"      with other Hayes V-9600 modems

   I hate it when incorrect or sloppy terminology results in misleading posts, 
but I'm not above making mistakes of my own...
