[comp.sys.next] 9600 baud modems

rab@speech1.cs.cmu.edu (Robert Brennan) (06/17/91)

I am looking for a new pair of 9600 baud modems.  I have been using two
Trailblazers very successfully but we need to purchase additional modems.
They need to be as reliable and as fast, even faster if possible, than
the Trailblazers, work reliably with SLIP and ideally have fax capabilities.
(I am not even sure there are 9600 baud modems with fax capabilities, but it
would be nice.)
So, is the Trailblazer still the way to go or are there others that are
better?

I use an Anchor 96E5, which works with the NeXT very well. At the
moment I can use V.32 and V.42, soon there will be a V.32bis and
V.42bis and fax possible (sierra). (V.42bis in about two weeks, V.32bis
in 3-4 weeks and fax should work in 1-2 months.) But maybe all this is
already possible in the US. (The EPROM code is already set up for all
that stuff) - BTW the modem is connected to the NeXT with 38400 Baud.

Fazit: I'm absolutely satisfied with the modem for a reasonable price
(speaking for Germany).

  Why not get a T1600 which is going to be upgraded to T1600 which is going
to be upgraded to v32bis real soon now, or the T2500 which has v32 but
no promise of an upgrade. I use a T2500 and am pretty happy with it.
Telebit tech support is the tops, though. :-)

DO NOT -I will repeat this- DO NOT get an ANCHOR modem. I've had nothing
but problems with one of the three that we purchased AND SINCE THE COMPANY
WENT BELLY UP, getting warranty service on these boat ANCHOR's will be 
next to impossible. An appropriately named product.

An extremely pissed customer,

why  even wait on Telebit when other vendors have been shipping v.32bis
now for 6 months?

Larry's right! I've done some shopping around and found the US Robotics
Courier V.32bis to be a damn good deal for a high end (and extremely reliable)
modem. It is compatible with more V.32 and V.32bis modems than other brands
which I've evaluated (ATI, Microcom). The pricing is quite competitive too.
For example, I am selling the USR Courier V.32bis external modem for less than
$700 (Canadian), and I am sure mail order sources in the US sell it for even
lower price.

I bought a MultiTech V32 for $551.  Haven't hooked to it the
NeXT yet, but will in the next couple days, as I just picked
up a cable today.

I've been using this modem for some months now, though, to
call our Vaxes (9600 Reliable Compressed is a great thing
to see after connecting!).

I use 3 Intel 9600EXs, one for dialin/dialout and the other two on slip
links.  They work realy well and unlike most other v32 modems they will
try to retrain up as well as down after line noise.  There is a rumor
that Intel will do an upgrade to v32 but I don't know for certain, you
might try calling them about it.
They do support v42bis and all the mnp trash, er, I mean protocols, and
using v42bis on text files I see ftp throughput along the order of
2.8 K / second (damn good in my book) with the interface locked at
384000 bps.

For slip the PEP stuff is useless.  If you are doing a lot of UUCP, especaily
overseas (satelite or anything else with long delays) then PEP is the
ONLY way to go.  I've not played with the t1600 but if my old TrailBlazer+
is any indication all TeleBit modems should be first rate.

Mail me if you have any questions on the Intels, I know them fairly well.

Cheers,

If you have implemented RFC1144 VJ TCP header compression, PEP modems
are quite useful for SLIP and PPP.  PEP will hold the line when
nothing else will, FTP throughput is reasonable, and interactive
response is survivable.

Hmm - must be real good.
Is it possible to get one of these over here. (to germany)
In other words. May I order the modem by e-mail, or is there an other
way to get it?

Thanks a lot
and 
so long

I counter with:
This is only true if you have only *one* thing going on over the
link.  I don't know about anyone else but we use slip here for
a metro-net (RAINet) and at any given time we have things going
on in all directions (nntp news, smtp mail, rlogins, ftps and more).
While we have not tried trailblazers on our slip links our trafic
realy does NEED full duplex capability.  I beleive anyone who is
running slip will have multiple IP connections going at once,
otherwise they are going to be better off dialing out with kermit.
Interactive throughput is MUCH better, there is no packet overhead
when typing.
In any case I do agree (I think I even said this) that the PEP
modems will work like no other when the delays are long.  I do
have one and I'll swear by it for UUCP work, still the best.

I've heard of a company that is selling generic 9600 baud V32 w/ V42bis 
modems for around $250-300. The name of the company is Image. But I have 
no idea what their # is does anyone know ?

I must put in a vote for Trailblazer here.  I have an old trailblazer plus
which Telebit has upgraded twice for free (Yoiks!).  These people have been
the some of the most knowlegeable and conscientious technical support
folks I've ever encountered.  

No connection with Telebit other than as a recipient of the new ROMs which
upgrade my Trailblazer to V.42bis.

I concur.  Telebit Tech support is far and away better than that of any
other company I've dealt with.  Telebit manuals are the best I've seen.
And they stand behind their product; I've received a free replacement
power supply for my out-of-warranty T1000, and am right now testing a
free ROM upgrade for one of our Trailblazers (needed because of their
change to PEP).  Companies like Telebit deserve to be supported.

   I concur.  Telebit Tech support is far and away better than that of any
   other company I've dealt with.  Telebit manuals are the best I've seen.
   And they stand behind their product; I've received a free replacement

[This is part of an ongoing discussion.  Before going with Telebit
based on past performance, go back and skim this thread.  Pay
attention to Marty's (likier@telebit.com) article about Telebit's
diversification and allocation of scarce resources to non-modem
projects.]

It is sentiment like this that encouraged me to buy my T1600's.  Based
on their past performance I figured I wouldn't have to dig too deep
when the time came to upgrade the newly designed T1600 to the V.32bis
standard.  I am quite disturbed by the news that this upgrade will
cost ~$250.  Apparently the engineers designing the T1600 did not give
it (or maybe management chose to not have them give it, who knows...)
enough muscle to do V.32bis, so a hardware swap is necessary. 

I wonder what that hardware *really* cost Telebit.  Not including
development costs, advertising, support, etc...  I agree that these
things need to be recovered, but I already paid for that when I bought
the modem the first time around.  The thought that they might be using
this as an opportunity to make money on me twice only makes me feel
more like I made a mistake.

One was to summarize my feelings on this matter is that I never
intended to buy a V.32 modem, I was shopping for a V.32bis modem.  I
was willing to consider vendors who didn't quite have their V.32bis
modem out yet, but only those whose product might be "worth the wait"
and whose past performance suggested that the upgrade path wouldn't be
too traumatic.

Like I said in a previous article, I'm going to sit tight until the
upgrade is really available and all the facts are in before I decide
once and for all whether or not I made a mistake.  I'm not too
optimistic though; it appears that the outcome is going to be that I
could have three V.32bis modems with 6 months time in the field for
the price my two Telebits.  Loyalty can be quite expensive...
