Not sure where they got it from but the Annex went to Nortel.

Yup and the Micom switch was it's competitor. Used 'em at DEC before
they had the LAT in our office.
As far as the terminal services over cable head end. Sytek had
LocalNet20 boxes which went to the serial ports on pc's and VT100's at
Fort Monmouth in New Jersey as part of the CASPR project.
I found this on line:
http://www.historyofcomputercommunications.info/Book/7/7.16-Sytek-BroadbandNetworkNeedingCash.html
The book seems to have a lot of good stuff there...
In February 1981, Sytek began shipping their comparatively inexpensive
two-port broadband terminal server: LocalNet 20. A direct consequence of
its Lincoln Lab development contract, two LocalNet 20s, costing a total
of $2,500, made a network.
Although both Sytek and UB, with its NUI-1, positioned their products as
terminal servers, Sytek’s customers tended to be those wanting to build
campus-wide networks whereas UB’s wanted departmental networks. In
practice,
Sytek and UB sold to any customer without thought of niches or market
segmentation, for the lack of buying customers dwarfed the annoyances of
competition, a condition soon to be exacerbated by an onslaught of
companies
offering every imaginable means of interconnecting computers and
peripherals.
In having diverted resources to LocalNet 20, consulting revenues
contracted,
and Sytek management had little choice but to raise capital. They began
talking to venture capitalists.
