IBM used to sell a broadband "PCNet" card. You might have to experiment to find out what you could run over it, though. I heard, once, that someone had managed to run PC/TCP over it, with some IBM driver, but we've never tried it. Maybe IBM can tell you more.

PC/TCP for Token-Ring runs just fine over it. It also works with most packages which support packet drivers like CUTCP, KA9Q, NCSA. Also, MD-DOS/IP from University of Maryland supports PCNet cards. marc ------ Marc Levesque Computing Services University of New Brunswick Fredericton, NB Canada marc@unb.ca

The original requester was somewhat vague in his first request, but later clarified that he needs a MAP compatabile product. SO THE IBM CARD WILL NOT WORK!!!!. On broadband there are many details that must be correct. The modulation scheme (AM,FM,QPSK,BPSK) must be the same, the "scrambling algorithim" (QPSK) must be the same. The TX/RX frequencies must be the same, the bandwidth of the service channel must be the same (6,12 or 18 MHZ). If you are implementing a new system then you have more leeway, but on an existing system everything must match! You can't expect two different broadband data transport channels to be compatible any more then you would expect your Television to be compatible with your celluar phone. Both use RF, but that's where the similarities end. The original requestor stated that the existing system was MAP, so he needs to look ONLY at MAP compliant products. (MAP is IEEE 802.4) If he/she is willing to look at a new "data channel" I would suggest 802.3 10BROAD36, but even then its at $500/port IF you need 8 ports otherwise it's more like 2K/port. Also with 10BROAD36 you can only go 3600 meters "round trip" (to the headend and back) Fairchild and Chipcom both sell 10BROAD36 equipment and I know Chipcom also sells MAP stuff, Fairchild may also sell MAP now.

Because if I remember correctly the Chipcom needs two bridges. Its really desinged to bridge seperate ethernets via a MAP channel. If so, you probably have to have a bridge. What is the application? Could you use point to point RS232 modems to get back to the head-end? Oh yes, I manage a broadband network. -- ==================================================================== Bob Turner Network Manager, School of Engineering 513-229-3171 turner@udecc.engr.udayton.edu Univ. of Dayton, Engineering Computing Center-KL211, Dayton OH 45469

(617) 246-0900 FTP Software, Inc.?? 26 Princess Street, Wakefield, MA 01880 ----------------------------------------- Our oldest network still uses those hideous cards. Sytek which is now called Hughes manufactured them for IBM. Hughes has a TCP/IP product called PROLINC that runs on some of those cards but not on all versions. It only supports a model called IBM PC NET II (it has more memory than the regular PC NET cards). PC NET II is actually shorter than the regular cards. Since the LAN operating system here is Novell, I have been able to run the WIN/TCP (from Wollongong) on those cards and it works fine. Although, I must say that since this approach uses the IPX transport layer, the IP packets are encapsulated in IPX packets and I have had to dedicate a machine that runs another program from Wollongong that unwraps the IPX packets and extracts the IP ones out before they are sent to the IP router. By the way, IBM directs all inquiries about PC NET cards to Hughes. I am very interested in any other drivers that would allow running PC/TCP on PC NET cards. Hope this helps.

And the PC NET II card (Sytek.HLS 6110) works with Hughes' NDIS MAC driver for their 6120/30. That'll allow IPX via dis_pkt.dos (and all the other 'stuff that'll run on a packet driver) along with Lan Man, Vines PC/TCP etc. BTW: Dis_pkt.dos is FTP's Packet driver to NDIS driver adapter. -- John Robert Breeden, jbreeden@netcom.com, apple!netcom!jbreeden, ATTMAIL:!jbreeden ------------------------------------------------------------------- "The nice thing about standards is that you have so many to choose from.

Its nice to know that our first attempt at PC networking is still in use after all of these years. > Sytek which is now called Hughes manufactured them for IBM. Actually, Hughes LAN Systems designed and manufactured the card as well as portions of its corresponding adapter ROM interface: NetBIOS. I'm not really sure to what extent IBM was technically involved in the effort. This happened a long time ago, and few of the folks originally involved in that effort are still around. > Hughes has a TCP/IP product called PROLINC that runs on > some of those cards but not on all versions. It only supports > a model called IBM PC NET II (it has more memory than > the regular PC NET cards). PC NET II is actually shorter than > the regular cards. The original IBM PC Network adapter card (i.e. the Sytek 6110) is in fact fully supported by ProLINC v1.0. ProLINC v2.0 no longer supports the 6110, but it fully supports subsequent versions of the card, specifically the Sytek 6120 and its latest incarnation the HLS 6130. Additionally, The new IBM adapters - PCN II for the PC and PCN II/A for the PS/2 - are also fully supported by ProLINC. > Since the LAN operating system here is Novell, I have been > able to run the WIN/TCP (from Wollongong) on those cards > and it works fine.

ProLINC uses a different approach to providing concurrent Novell and TCP connections. Along with the TCP, NFS, and LAT protocols provided in the package, we also include an IPX stack with code that interfaces it directly to our Multiple Protocol Driver (MPD). As such, Netware and TCP (and LAT, and Banyan and LAN Man for that matter) can concurrently share the MPD interface without encapsulations. > > By the way, IBM directs all inquiries about PC NET cards to > Hughes. > > > I am very interested in any other drivers that would allow > running PC/TCP on PC NET cards. > The original PC Net cards are still supported by the IBM LAN Support Program. Conceptually, LAN Support could be used to run the ASI versions of both the PC/TCP stack and the Novell IPX. However, I can't make a specific recommendation in this regard since I haven't tested this combination myself. Nestor A.
