G.7xx is the working-document name for a project in (I think) SG XVIII
which will map ATM cells onto existing digital transmission systems.
It will eventually get a real number in the G.7__ range, hence the
name.  Yes, "direct ATM" is the cell-based interface.

Subject: vise G.7xx: ATM over PDH!
Organization: Nokia Telecommunications.

Hi there!

G.7xx is a new CCITT draft recommendation from Study Group XVIII
meeting held in Geneva, June 1992.

It specifies ATM cell mapping into Plesiochronous Digital Hierarchy
(PDH).

The following PDH bit rates are included:

        1 544  kbit/s (DS1)
        2 048   "     (E1)
        6 312   "     (DS2)
        8 448   "     (E2)
        34 368  "     (E3)
        44 736  "     (DS3)
        99 728  "     (in Japan?)
        139 264 "     (E4)

The physical interfaces for the bit rates above are based on
the CCITT G.703 standard. The transmission frame is octet structured with
125 us frame duration. The payload reserved for ATM cells and the path
overhead of the frame is dependent on the bit rate. Generally
the OAM principles for higher bit rates refer to the SDH standards.
However the compatibility between this specs and the SONET/SDH standard
could be better. E.g. see "Mapping of ATM cells into 139 264 kbit/s"!

Any comment on this, and why not on the other mappings as well?

-Jan

PS. The next CCITT Study Group XVIII meeting will be held in January 1993.
In case you might have something to contribute :-)

OK, I have a problem here:

  I am a migrating process, and am currently sitting at memory
associated with a file containing objects of a certain class.
I have arrived here via a series of exploratory hops from data node 
to data node, moving at each step when the local data met some
condition (I am a query moving through data).

  Now, having found the data I desire, I want to link this data directly
back to the location in memory where I started, thus building a memory
to memory VCI to satisfy my query.  Hence, I need to build a virtual path 
back to the locations from whence I came,  but I have no global knowledge 
about where I am, I have only a series of traces taking me from information 
node to information node back to the source of my travels.

  Problem:  I want to traverse back over my path, closing out any
loops appearing along the way back, possibly performing some local
optimization between hops looking for shorter paths.  This backward
path I traverse, takes me back through switches, processors, and files
contained at processors, updating the virtual path along the way.

  Don't tell me that a hidden hand in the network management will do this
for me, as that just begs the question.

This doesn't seem like a reasonable argument - 0.8 bits per baud seems
to be almost exactly as bad as 1.0 bits/baud for sending >100Mbit/s
over twisted pair. I would be surprised if a standard for ATM over
twisted pair didn't have a multiple-bit-per-baud modulation scheme,
given the limited bandwidth and (relative to fiber) good SNR of
twisted pair.

Of course there is still a price to be paid for reserving symbols for
framing overhead, but depending on the modulation scheme it may be
comparable to the SONET overhead, and could result in reduced
complexity.

  Prior to deployment of the new networks, we have to make expli-
cit their effect on the traditional mainframe business.  To para-
phrase the CEO of SUN, nobody benefits if IBM is dismembered.

  The  advocates  predict  very  low  cost,  low  latency,   high
bandwidth.   Hence,  the  user can add single processor boards to
the data center for less than $3000, with an attached  disc.   As
demonstrated  by  Sequent,  these clusters make for powerful data
base machines, and the design of the semantic data  model  favors
simple, single tasking operating systems on each processor.

  However, since the new network processes asynchronously migrate
through  this  semantic model, extracting some structured data to
be duplicated onto the desktop, the desktop  needs  multi-tasking
to  manage  its  interaction with the structures, yet continue to
offer an interface to the user.  The desktop  participates  as  a
partition in the larger semantic model.

  The paradox then is a resurgence of simple DOS like systems  in
the data center with an imperative for multi-tasking on the desk-
top.

  The new opportunity is for an OS/2 market on the desktop, while
the  demand for risc in the data center begs for a simple, single
tasking kernel.

Claude -

Thank you for posting this again.  This is one of the more frequently asked
questions I see on this group and here at cisco.  Perhaps we need a cisco-faq
group.

The reason you can't find that in the Router Products Configuration manual is
that it is not really a router command.  It is actually one of the terminal
server line commands that happens to work on the router.  I suspect that this
is because ther terminal server and router may share some (if not all) of the
line and exec code.  But many people are thankful that this command is 
available, once they know about it.

This command and other line commands are documented in the Communication
Server Configuration and Reference Guide.  This document set is available from
cisco as customer order number DOC-CS9.1

>o   How does the ASM-CS physically connect to the big iron to run tn3270?

  Both your ASM-CS and the big iron need to be on the network(Ethernet or
Token Ring) .  Your big iron also need to be able to communicate TCP/IP.
Basically, tn3270 is a version of telnet that emulate IBM3270 terminal.


>o   Is there an aggregate bit rate limitation on the CSC-16 serial card?

   You can set the bit rate on the CSC-16 up to 57.6 Kbps.  This is only 
useful for harwire terminal line. Most modem don't really give you such a
throughput.

>o   Can I open a socket connection to a serial port and dialog with it over
    the socket connection (reverse telnet?)?

   You can set up reverse telnet from the terminal server to the IBM7171 box.
I do that before our big blue run TCP/IP.  However, it will not be tn3270.  
You just use the regular telnet to make the connection.

  
>o   Can I do scripted dialing for an outdial using the ASM-CS as a modem pool?

   there are some connection strings that you can setup for connection.  I
don't use it a lot and therefore I would not make any comments.  Maybe someone
can tell you more about that..

Our csu/dsu gets an inband loopback about once a week.

Can noise (T1 line) look like a loopback?

I've got Cabetron Fiber-Optic Transceivers hanging off most the ports of my three
AGS+ units. Of the remainders, they are either 10BaseT itty-bitty-TPTs from ctron or
AUI Cables leading to corresponding ports in Cabletron hubs.

I have decided that I really need to find a better way than to hang the FOTs
off the router. True, it works for a while but after about a year or so our
AUI ports are starting to show the physical strain.  The LEDs are just obscured
enough to make it a real pain to get at them.

If I had the time & money (yeah... hundreds of thousands for infrastructure, but 
not a penny for tribute) to do it here's what I'd do:

I'd velcro all the transceivers to the side of the rack in rows, with all the fiber and AUI
cables tied together in bundles that feed into one or two pieces of innerduct that are
fastened to the back of the rack and lead down to the interfaces or over the the patch 
panel.  I'd label each transceiver with my zippy little Brother label-maker with 
building name, and subnet address for each protocol suite (IP: 129.120.2.0, IPX: E1000,etc)
and leave enough slack at the transceivers so I can pull a fiber pair or AUI
cable off it need be.  I'd also screw a 35mm film canister to the side of the rack
with 3 pair of each type of fiber connector protectors we use to keep them available
and dust-free.  Too bad AUI needs more than 8 leads.  It'd sure be great to use RJ-45s
for connectors on short AUI cables at the hubs.  Cabletron makes some nifty AUI cables
with thin flexible cables, but they're a bit too short for use at the hub -- we
tend to use them on workstations.

You can obtain the Microcode compatibility chart in a document called the

by asking for document DOC-MRN-9.1  It also contains a revision history for
each type of card.

  You have your configuration register at the CPU board set to netboot cisco11-csc3

	 Configuration register is 0x109
  
  What you need to do is  pull out the jumper on bit 3 and leave the

CPU bootstrap program).

   Well, it is set to do netboot so it does what it supposes

$ 3. It then went into a config dialogue where I had to enter the
$    the ethernet address and host name, etc. and confirm the info.

  That is the problem.  I suppose we are the only few cisco customers
that still don't the the NV-RAM in the box :-).  Start somewhere
in 8.3, cisco boot PROM will  automatically get into the 
dialogue menu if the box does not has NV-RAM.  Though the box still
send out Bootp request, it basically ignore the bootp return and drop
you into the configuration menu.  You just have to hope the box would
not crash in the middle of the night or weekend :-) as you have to

  The 9.1(1) PROM do that if you don't have the NV-RAM.  I have the

I received a set of new PROM  Version 9.1(1.5) which will put
your box back to "normal" behaviour.  It will do the  normal
bootp request and load the configuration files from your
TFTP server without getting into the menu.  Thanks again, Mary!!!

Yes, this will work, assuming of course you have your subnet masks set to 
255.255.255.0. The interface of the router needs an address in each subnet 
you want to run on that wire, but you can give multiple addresses to a 
single interface with the 'secondary' option of the 'ip address' command.
