Thanks to the 20 or so respondents to my original inquiry about the
potential use of a "restored" ILN connection. That was a bit more of a
response than I anticipated since it IS summertime! Hopefully all of you
will get away for a break!!
While you all mentioned having concerns about bandwidth requirements, it
is my understanding that video calls use 384 - and can go down as low as
256 satisfactorily - and with Layer 3 switches bandwidth can be adjusted
to control both the video and other data that flows through the "pipes".
If the majority of use is text email and text and minimal image transfer
- minimal activity, it is quite possible that some videoconferencing
will be possible during the school day..... depending on your
connection. If one has 1.5 DSL or T-1 it should be OK to do both video
and other activities. Part of our responsibility here at DOE will be to
provide you with technical assistance to see what tweaks might make it
possible to use ILN during normal operational hours. So please keep an
open mind about when the system might be available to users.
We'll keep you posted via this list about upcoming plans and the release
of an RFP to provide a management structure for the system.

Hello everyone -
You may know that the Department of Education has been working
to restore the ILN system to some level of functionality in the next
school year using Internet Protocol (IP), but without ATM. We are
interested in and will be working toward a more permanent solution in
order to maintain a statewide videoconferencing network to support
schools. The Department has been successful in securing significant
bandwidth to support the system and has funding to hire a management
team to provide technical support at both the state and local levels,
programmatic support, and to provide advice in configuring the polycom
and your local gateway to the Internet for ILN use. There will be no
additional cost to the school district for any of the above services or
for use of the system, but..... NOTE that SOME local systems may need to
be upgraded/increase bandwidth in order to connect well enough with the
ILN bridge. The costs of such upgrades or bandwidth improvements must be
by the local district.
Virtually all of the equipment currently in place will still be
usable in the new system, although some modification of the existing
routers may be required.
The biggest question for local educators is whether there is
adequate existing local bandwidth to support simultaneous use of ILN
along with Internet use on the part of staff and students.
So this question is for Technology Coordinator-types: Will you
revive ILN at your local level if it is made available to you as
described above? Please let me know so we can get a general reading of
the level of interest.
Many thanks -
Bill Romond, Vermont Department of Education
