need contact info for broadxent

I am looking for the contact info for Broadxent. It seems all the phone
numbers listed are no longer in service, and all emails sent to them just
sucked into a black hole.

Specifically, I am looking for the document of the telnet command line
interface for their Briteport 8120 router, so in case you have it, I'd
appreciate you let me know. It didn't come with the router, and I can't
reach the company.
Thanks...
