The folks in Andrew-land are making some significant changes
to their dialup services. There are two items that will affect
ECE folks. First, Andrew dialups will no longer accept non-andrew
user domains (such as ECE). So, you won't be able to login as
joe@ece.cmu.edu  Second, ARA (Appletalk Remote Access) using
"classic" networking on older Macintosh computers will no longer
be supported. This means that Mac users will have to switch
to PPP.

Subject: Changes coming to Computing Services Dialups

Folks,

Changes are coming to the Computing Services dialups, and here is 
the basic scoop:

Over the course of the Fall 1999 semester - all of the public 
dialups supported by Computing Services are being upgraded to 
integrated V.90/ISDN remote access servers. By the time the 
semester is over - all public dialups will be using Cisco 
AS5300 servers, instead of the current conglomeration of modems
and terminal servers. 

This will be done "one dialup number" at a time. 

We're setting up the digital circuits to feed the new units, and
verifying that everything works.  Then, on a given day, one of 
the familiar "lead numbers" will be ported to the new circuits. 
This will mean that the specified lead number will be out of 
service for a short (see note) time while the transition happens.  

When the number has been ported to the new service, calls
placed to it will terminate on the new equipment - no change 
necessary for the user, with some minor exceptions.

Three functions that were supported on the Annex terminal
servers will not be supported on the new dialups.  These are:

    1) Statically assigned IP addresses on the dialups.

    2) Appletalk Remote Access (ARA) using "classic" networking on
        older Macintosh computers (prior to Mac OS 8).

    3) Non-andrew user domains  (cs.cmu.edu, ece.cmu.edu, pcs.edu,
        and others)

Details on these changes will be available _soon_ on Network Group's 
webserver at

        http://www.net.cmu.edu/docs/services/remote/changes.html

The retirement of these services affects less than 4.7% of our
user community, and users who are affected either already have, 
or will receive personal email about the changes prior to the 
first upgrade. 

The actual dates involved are still being determined, but 268-9900
is to be ported on Monday, September 13th, 1999.  9900 is currently 
served by forty-five 14.4K modems, and are barely used until the 
main pool (268-9000) gets filled up during the evening prime-time. 
We're expecting the outage to only last a few minutes, but as this
is the first time we're ever tried this, we're going to announce an
outage from 10:30 to 3:00 PM on this small group of modems.

268-9000 will be ported "midsemester."  The target date at this point
is planned for Monday, October 18.  If this date is bad - please 
let me (jny+@cmu.edu) know ASAP.  Since this will have fairly
major impact on our dialup capacity when the change is made, every
effort will be made to minimize the amount of time this change will 
take.  We're hoping that September 13th's move will provide us with 
the experience to make the October move a very smooth transition.  

The final changes will be to 683-5656, and 681-9006, and will 
occur after the academic semester has ended.  

Questions, concerns, comments, can be sent my way (jny+@cmu.edu)
but sending them thru dc0m (where more folks than me will see 
your mail) is fine too.
