[comp.dcom.lans] Help! Netware Link/Async

swie@cs.umn.edu (S. T. Tan) (08/11/90)

Does anybody familiar with Netware Link/Async communication software ?
If you are familiar, could you help me answer the following questions:
- Is it a reliable product ?
- How many LANs can be connected together ?
- Does it work with Netware-386 ver. 3.1 ?
- Can I use to access / update database records from a remote workstation ?
- I was told that this software is included in Netware-286 SFT, is it ?
- Is there a better modem than Hayes V series (2400 or 9600 baud) to 
  connect the two LANs together ?

Is there a better option to connect two Netware LANs together ?

Thanks in advance

Sounds like you are mixing the products.  Novell and CSI have many products
and you have to be more specific on what you need.  From you questions, you
sound like you needed remote dial-up for workstations into a LAN and you also
wanted to connect two or more LANs together.  Yes, Netware 286 (both Advanced
2.15 and 2.15 SFT) comes with software that lets you do what you wanted.  
BUT you should consider this very closely, because for connecting LANs 
(Bridging is the term) this is really too slow (basing this assumption from
your question relating to Netware 386, you must have a pretty good size user
base).  For workstation dialup it might be okay depending on what performance
criterior.

Here is what I think is your answer:

Workstation Dialup: Install a Async Comm Server.  This you can maxed out to 
	16 concurrent sessions on one server pc (4 cards, 4 users per card).
	Of course you need 1 modem per session. 

LAN Bridging: You should consider getting a X.25 Bridge and tying the LANs
	together with synchronous modem (V.32, not Hayes).  This gives you
	full duplex (two ways concurrently) and efficient data transfer,  
	because the data are packetized (buffered transmission).

Caveat: I don't know how wide spread you LANs are.  If they are within 6 KM
	from each other, you can use microwave dishes or fiber (if your
	budget allowed).  Both methods gives you the same bandwidth as locally
	attached nodes, but microwave is less reliable.  It is subject to 
	obstructions (building maintenance crew bodily blocking the path) and
	weather conditions (heavy snow).

I have allot of experience in LAN connectivity and system integration and
would gladly help you in whatever ways I can.  Your can reach me at

P.S. - For the X.25 approach, if you need to connect more than 2 LANs together
	and don't want to install multiple point-to-point connections between
	the LANS, you have to consider installing a switch (known as a SVC - 
	switched virtual circuit) or use a commercial network (Tymnet, Telenet,
	Infonet, etc.).
	
	Also, be aware that the fiber and microwave approach requires more
	up front investment, but have cost close to nothing to operate it.
