8.1 Hardware that does async PPP



[Started by: emv@msen.com (Edward Vielmetti) and heavily edited, to include
 information from the net, by i.s.]

This is a list of hardware that supports async PPP, in the form
of a terminal server or terminal server / router combination.

  The NetBlazer supports 24 async lines.  An individual line can be
  run at 115.2Kbps.  A benchmark by LANQUEST showed the NetBlazer
  could run PPP on 24 async lines at 38.4Kbps.  I don't know of any
  customers who run exclusively PPP on 24 lines, but I know of several
  that run mixtures of SLIP and PPP on 24 lines.

  A NetBlazer works flawlessly for remote site PPP/SLIP links.  As a term
  server it doesn't fit the bill.  And a bit costly.

  They have 10-, 20- and 30-port configurations.  List prices
  ranging from ~US$2.7K to ~US$3.8K.  Contact <doug@livingston.com>
  for more information.

- Xylogics Annex 3              (8-64 ports - release 7.0 firmware)

  We don't have a sync PPP version yet, mostly because we don't support
  sync serial yet.  That is scheduled for the R8.1 release.

  We have had async PPP since our R7.0 release in October 1992 for our
  Annex 3 and Micro Annex XL platforms.  PPP is not supported on the (now
  obsolete) Annex 2 nor on the Micro Annex ELS.

  The Annex 3 can be customer-upgraded from 8 to 64 async serial lines,
  with full modem controls on each line, and two to three i376 processors.
  (The i376 is an embedded version of the 80386 which does not have an
  MMU.)  The motherboard has one i376 and each serial card (maximum two)
  has one.  Packet routing and user-level functions are handled on the
  motherboard, while framing and PPP/SLIP link-level processing are done
  on the serial cards.

  I have been *VERY* happy with my Xylogics terminal servers I have to Anne
x
  II's and a Annex 3.  They were designed for the Unix type person, and tak
e
  2 mins to get working on the network.  Port configuration will take longe
r,
  but normally you only have a few sets of configurations "modem dialin hig
h
  speed" etc.  Two thumbs up to this company, now if they didn't cost so
  much. :) :)

  I tested one of these, they come in 8-16 port configurations, a TCP or LA
T or
  TCP/LAT version.  Very VMS like, I would guess a off spring of DECservers
.
  Cheaper than the Xylogics in Price.  Didn't fit my feel due to the VMSish
  help and commands.

8.2 Hardware that supports sync PPP


Newsgroups: comp.protocols.ppp
Original-From: emv@msen.com (Edward Vielmetti), but heavily edited by i.s.

Note that sync PPP is rather well established and it's not surprising
to see lots of vendors using it as their only sync serial line
protocol.  Various folks do various of the configuration options,
anywhere from a full implementation to very bare bones.

The price point is arbitrary.  These are list prices for the cheapest
box that has at least 1 sync PPP port that runs at 56 kb/sec plus one
ethernet.  Prices approximate, your milage may vary, contact your
vendor for details.

  As of this February (93), the NetBlazer/40 supports up to 10 sync ports.
  All can be run at 128Kbps and several can be run at 2Mbps (I don't have
  any field or independent test data on how many can be run at 2Mbps, but I
  think that the answer is at least 2).

   HDLC driver for sun4c ttya and ttyb included with PPP software. Works
   only with SunOS  "haven't been able to   extract the information from
   Sun that we need to make it work under   SunOS 4.1.* or Solaris 2.*.
   
     The HDLC driver works on NeXTs under NeXTStep 2.[12], but because of
   NeXTStep's interrupt structure, we can only get it up to 19200 sync.
   
     It's also available from ftp.morningstar.com:pub/tools/sun-hdlc.tar.Z.
     It started as something from one of Torben Nielsen 's   grad students,
   and we're required to pass along any changes we make to   it.  We hope
   that if someone gets it working under 4.1.*, they'll be nice   enough to
   pass their changes along too."
