- Network Status and Performance
The network is back in a counter-rotating token ring mode. The
ring was operating in a wrapped mode for a couple of months,
during which IRTF respliced their fiber as part of their
renovation. The splicing was done by a local contractor in Kona,
who did a good job once all our requirements have been explained
Additional Ethernets can now be added to the CNX-600 at HP --
contact Tjet Sun if interested. There are three ethernet subnets
- Router Maintenance
The maintenance contract for all the Proteon routers on the FDDI
ring is in place. The joint maintenance contract extends from
July 1, 1994 to June 30, 1995. In addition to basic maintenance,
there is one hot spare for each one of the components on
maintenance. As of this moment, we have not received the
CNX600, the quad ethernet, and the quad serial hot spares.
Proteon is aware of this matter. A schedule of the
costs is attached.
- MKOCN Info on MOSAIC
Tjet Sun announced that a MKOCN MOSAIC is available to the users.
It can be reached at
through Mosaic is accepted and preferred.
There are two password within the MKOCN Mosaic pages. Please send
Tjet Sun e-mail for further information.
- Next Maintenance Trip
The next scheduled maintenance trip for MKO ComNet will be later
this summer. During this trip, we will replace the jumpers at the
main distribution panel to make it more manageable. In addition we
will test fibers which appear to be broken or have a high loss. We
have identified fibers to CFHT, CSO, and IRTF which are currently
unusable. In order to perform the testing we will attempt to rent
an OTDR from sources yet to be identified. The preliminary cost
estimates from Exsell are: $365/week, $660/2 weeks, $1200/month.
Another option is GE rental.
There should be no extended downtime during this maintenance trip
to any of the telescopes.
- Network Expansion
IfA is working with Hawaiian Tel to improve the bandwidth off the
mountain. Progress has been made. A more comprehensive overview of
immediate and future plans will be presented at the annual Mauna
Kea Users' Committee meeting, to be held at the Royal Waikoloan,
- Next Meeting
Friday October 14, 10:00 am at CFHT.
