In our area we have a mix of Sun-2 and Sun-3 hardware. The Sun-3's all
communicate over thinwire Ethernet. One conventional Ethernet
transceiver on a six-foot length of fat yellow Ethernet cable connects
the thinwire segment to a DELNI. The Sun-2s are connected to the DELNI
with transceiver cables.
We have recently renovated our office, including thinwire Ethernet going
to all offices from a Cabletron DEMPR box. Since the transceiver cables
we use with the Sun-2s are heavy (teflon) and limited in length we want
to convert the Sun-2s to work with thinwire Ethernet.
DEC's DESTA product looked like what we needed. It is a thinwire
transceiver that doesn't need short segments of fat ether cable or
BNC-to-N adapters, and the price (~$275) is about right.
Then an engineer in our Facilities department pointed out that the Sun-3
thinwire interface is "Level 2" Ethernet and that the DESTA and DEMPR
are 802.3 devices. She doesn't think they will necessarily play
together.
So what do you people think? Have any of you used DESTAs or other
thinwire transceivers on a thinwire network with Sun-2s, Sun-3s, and
DEMPRs? Can you recommend a solution to my problem?
Thanks in advance.
