about a year ago one of our administrative departments here at york installed
a CATV backbone throughout our main campus; unfortunately they didn't consult
with anyone else and configured it for low-split operation; recently, i've
been investigating the possibilities of appropriating one of the channels
on the backbone for broadband ethernet
i suppose that i should mention that the original intent of the CATV
installation was to provide a couple of channels of live video feeds
as well as to allow the university to re-sell television service to student
residences; so far as i know, at this point not much more has happened
beyond the laying of the backbone
the vendors that i've contacted so far can operate only on mid-split and
high-split systems
1. why should this be so? even in low-split i have some number of channels
running in the 'reverse' direction... why would these vendors place
this seemingly artificial restriction on themselves?
2. does anyone know of any vendor(s) that offer a low-split broadband
ethernet product that can plug-in to an existing CATV network?
3. forgetting for just a moment the political implications... it is
possible to simply replace the head-end frequency translator to
change the system from low-split to let's say mid-split? i have heard
said that this cannot be done because each amplifier along the backbone
embodies the split characteristic of the entire system... head-ends
are relatively cheap but it would be prohibitive to replace each of
the amplifiers as well (or can they be re-tuned/re-wired?)
any help at all in this matter will be appreciated
