Does anyone know if Apple or an Apple vendor is planning on creating
an ATM interface on a NuBus adapter with a QuickRing implementation?

It would seem such a set-up with a couple of other QuickRing boards
(like a video processing board) would allow for a mac to process,
manipulated (etc.), broadcast quality or HDTV video in real-time
(and then send it off to be broadcast/retransmitted.)

802.3 standard lawyers not withstanding, using the same signal to
indicate both "Collision" and "Transceiver OK" is a MAJOR DESIGN FLAW.

I'm still waiting for someone to tell me exactly why turning SQE off
on every transceiver is a bad idea...  I am relieved to learn that
most, if not all, software/firmware ignores SQE even when it is
enabled.  

For now SQE stays disabled on my net.  The risk of losing one computer
is trivial compared to the risk of losing the entire network.  (I'm
always open to and invite arguements against this policy.)

IMPORTANT: Remember, the standard does say turn off SQE/Heartbeat/Jam
when connecting a transceiver to a repeater or hub.  If you forget
this your throughput will be very poor.

   I've never seen a modem playing higher than 2 Mbps (E1, G.703)...

The problem is how to send, in a single stream, more than 2Mbps
across a WAN.  Money being no object, one could easily lease a T3, and
purchase a CSU/DSU that could clock a V.35/HSSI port on a router from anywhere
between 64kbps to 44Mbps.

Unfortunately, not all of us has the resources of Ross Perot.  Two other 
options exist today:

1.  T1 Inverse Multiplexing

    This type of device (Timeplex offer such) takes multiple T1 lines,
    compensates for the different delay on each T1, and produces a single
    N*T1 bps V.35/HSSI stream of data.  For example, three T1s would produce
    approx. 4.6Mbps.

2.  ISDN Inverse Multiplexing

    ISDN multiplexers (using NFAS) are now able to make switched N*64kbps
    calls, where 64kbps B-channel increaments from multiple PRI lines are
    multiplexed together, delay compensated, and combined to make a single
    N*64kbps call.  A lead change on the router's V.35 port could cause
    the call to be dialed.

    The "Bonding" inverse multiplexing standard is almost complete.

Does this make sense with Cisco.  Does Cisco do something like PPP

I have some CGS's that my company isn't going to end up using.  They
are the basic CGS chassis with a CSC/3 processor and a 2e2t card.

The CGS box is a 2 slot and processor only, in other words if you
kept the 2e2t card in it you could only add one more card.  

They have never been used.  I can probably offer you some reasonable
length warranty.  I think they also have the bridging software, I'll
check on that if you are interested.  They should be fully eligible
for maintainance, of course.  I think maint was running about $800/yr
on the CSC/3 based CGS's last time I checked.

I'd like $7000 each, according to my calculation that is a 40 percent
discount off list and enough change to buy a year of maintanance.

I have a link here where we use Digital Link DL3000 muxes to break up a T3
microwave link ... one of the pieces is a ~32Mbit data channel between two
AGS+'s on HSSI.

Several companies now sell HSSI to T3 "modems" if you want to call them that.
I think the term DSU is probably more correct ...

Nodes c & e wish to see services available via LAT, excluding LAT services
from a, b & d

Nodes a, b & d wish to see services available via LAT, excluding LAT
services  from c & e.

We envisage using filtering applied to interfaces to remove unwanted
service broadcasts from being displayed or generated (to cut down on
broadcast traffic).

However we believe there may be a better way to accomplish this, without
unduly affecting network performance.

Organization: St. Olaf College; Northfield, MN
Date: Thu, 30 Jul 1992 19:27:46 GMT

Greetings once again,

Many thanks to all that helped out in clarifying how access lists work
on the cisco.

This time I'm back looking for some advice on doing AppleTalk routing.
Our 20-odd nets are currently bridging non-IP traffic (e.g. AppleTalk
and IPX).  We have an AppleTalk router on each ethernet that does
traffic isolation and Zone creation.  (I hope the terminology I'm
using makes sense; I'm not a very in-the-know AppleTalk person...)

What we'd like to do is have the cisco route AppleTalk traffic.
The sample configuration in the cisco manual seems straightforward:

	appletalk routing
	[for interface in 0-23]
		interface ether $interface
		appletalk cable-range 0-0

We would like the cisco to auto-discover everything, so we're using "0-0"
as the cable range.  Unfortunately while we are playing around with the 
AppleTalk routing, the entire campus AppleTalk network is down.   For 
this reason (!) I'd like to be sure, with y'all's help, that we know
what we're doing...

A "show apple inter" shows a message along the lines of:

	Ethernet 1 is up; line protocol is up
	AppleTalk routing is disabled, Unknown status
	AppleTalk Cable Range is 0-0

In auto-discovery mode the cisco seemed not to see any AppleTalk traffic.
We also put in an explicit cable range and zone name on a couple of 
interfaces as a test, but this didn't help.

Are we missing something obvious here? 

Thanks again in advance for your help!

E2 is 8Mbps, which is faster than cisco's T (<=4Mbps) interfaces or IGS
(<=7Mbps) will go. Or is it? I've been told by cisco that the IGS maxs at
7, but does the MCI/SCI really 'only' go to 4?

This is of interest to us as we are about to create a 'downtown' campus,
probably linked to the main campus via 15 or 23GHz microwave. This
provides a G.703 interface with transmission rates of 2,4x2,8,2x8 or 
8x2Mbps. We suspect that a 2Mbps link will be too slow (NFS cross mounts),
but nx2 links would be very expensive and the cisco won't handle 8.

1.  Standard states that an ethernet network may have 101 segments, (1
backbone and 100 branch segments.)  Do segments off of a repeater, (the
repeater taps directly into the backbone), count towards the 100 branch
segment total?  A multiport transceiver?

2.  How do you count the 1024 station limit.  (This is similar to number one.
In a network with bridges, routers, repeaters, etc.... what devices count
toward the 1024?)

3.  If a building has 2 LAN's, each with its own RG-8 backbone, and you want
to connect them together.... What is the best way?  Can you stick a
transceiver on both pieces and run RG-58 between them?  Why/Why not?

4.  In a magazine I read that the Max. length for a transceiver drop cable is
50 meters, but "When using the more flexible office transceiver cabling, the
maximum cable length is 12.5 meters."  What is this 'flexible office 
transceiver cabling'?

5.  What is the difference between a HUB and a repeater?  What is a HUB?

6.  What is cascading repeater/HUB's?

7.  What are the counts for repeaters, routers, bridges?  How do you count 
them?  ie.... When do they reset?  ie.. after passing through a router?

Two last notes and then I promise to stay out of this...

On many hosts it is impossible to capture long collisions, only a few
hosts even bother to tell you about them.  You need something like
a LANalyzer to capture the packets.  It is important to know how far
into the packet the collision was, close values point to cable length
and longer ones other problems.

It needs to be pointed out one more time that long collisions are
>not possible< in a correctly operating network.  The main problem
when you find them is what the ethernet chipsets do,  e.g. the major 
chipset simply discards them.  They are not handled in the same way
that normal collisions are.  {And if you've never seen what seemingly
small numbers of discarded packets do to net throughput you should take
a look.}

I an wanting to configure a 150m piece of thinwire cable as an
inter-repeater link.  At one end I have Isolan gear - and EC/4
with a coax line card in it.

The other end is not yet purchased, but I am thinking of a
DECrepeater 90C :

|
|--EC/4 ------------------------------- DECrepeater 90C
|                                        |  |  |  |
|                                        |  |  |  |
campus					thinwire strands to various
backbone                                parts of a building.

Can someone confirm that this will work, and in particular that a
DECrepeater 90C can be used as one end of an inter repeater link ?

Thanks,
