8. PPP HARDWARE
Before even thinking of reading this document, refer to the disclaimer
in part 1 of the "frequently asked questions".
8.1 Hardware that does async PPP
[Started by: email@example.com (Edward Vielmetti) and heavily edited, to
include information from the net, by i.s.] This is an INCOMPLETE list
of hardware that supports async PPP, in the form of a terminal server or
terminal server / router combination.

SELF-DESCRIPTION Date: Wed, 07 Sep 94 13:06:19 EDT From:
Jesse Walker <firstname.lastname@example.org>
Digital Equipment Corporation's DECserver family of Network Access
Servers support IP, IPX, and AppleTalk over PPP,
with interoperability demonstrated with all the
commonly available client implementations for
all three protocols. The DECserver family
includes the DECserver 90M, 90TL, 700, and 900TM.
The 90M and 90TL are 8 asynch line servers,
supporting speeds up 57.6 Kbps. The 700 comes in
two models: an 8 asynch line version using DB25
connectors that support full modem control, and
a 16 asynch line model. The 900 is a 32 asynch
line server. The 700 and 900 class machines
support speeds up to 115.2 Kbps. All work well
with any Hayes compatible modem. All except the
90TL have a FLASH RAM option, or can be loaded
either via BOOTP or MOP.

SELF-DESCRIPTION Date: Mon, 12 Sep 94 09:57:58 PDT From:
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

SELF-DESCRIPTION From: email@example.com (James Carlson) Date:

Current version has IPCP and PAP. We don't have a sync PPP version yet,
mostly because we don't support sync serial yet.
That is scheduled for the R9.3 release, along with
ATCP, IPXCP and CHAP.
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.
The Remote Annex has the same architecture, but with a TI486SLC2
processor instead of the 80376. It's about twice
The Remote Annex 6100 ... contains a T1 CSU, a channel bank, up to 24
V.34 Microcom modems, and a high- performance
terminal and communications server with two 32-bit
80486 processors. PPP with IPCP, IPXCP, and ATCP
NCP protocols, and PAP and CHAP security are
[The Remote Annex 6300 ...] does async PPP over V.34 dial-up and over
V.120 ISDN TA dial-up, and does sync PPP over sync
(56 or 64Kbps) dial-up. It also supports the LCP
options over sync necessary to allow async-to-sync
PPP dial-up converters (like the ZyXEL 2864 ISDN
TA) to work.

I have been *VERY* happy with my Xylogics terminal servers I have to
Annex II's and a Annex 3. They were designed
for the Unix type person, and take 2 mins to get
working on the network. Port configuration will
take longer, but normally you only have a few
sets of configurations "modem dialin high speed"
etc. Two thumbs up to this company, now if they
didn't cost so much. :) :)
8.1.6 DATABILITY VCP 200/300 ( ??? )
Opinion From: email@example.com (Brian J. Smith)
Date: Fri, 27 Nov 92 23:35:18 GMT
I tested one of these, they come in 8-16 port configurations, a TCP or
LAT 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
Original-From: firstname.lastname@example.org (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.

From: email@example.com (Charlie Slater)
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).

SnapLink SCSI-attached serial interface for Unix systems
1 T1 + 2 56K, RS-232 or RS-449
HDLC driver for sun4c ttya and ttyb included with PPP software. Works
only with SunOS <= 4.0.3c. Morning Star "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., 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 <torben@Hawaii.Edu>'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."

SOFTWARE FORGE SYNC. BOARD FOR IBM-PCS
Self-Description Software Forge Ltd (part of the Racal-Airtech
group in the UK) have a sync. comms card for a PC
that can run PPP and X.25 over leased line, PSTN
dial-up and ISDN. Standard interfaces are
provided (Packet Driver and ODI). These actually
emulate an Ethernet interface, so a vast range of
third-party protocol stacks (IP and IPX) can be
supported. Software Forge can also provide an IP
Router based on the same card.
N.B. - this is a _sync_ comms card, ie it can drive ISDN at the full 64K.
Channel aggregation is also supported (RFC 1717 - "PPP Multilink").
