A 10Mhz to T1 clock generator would be a cool project but in the event I were to need a standalone T1 clock source at home I'd probably just grab a CSU / DSU from ebay (or ask one of my former employers if they would let me acquire one from their junk pile) that could serve as clock generator.
One day I suspect I'd eventually find a use for two such devices to set up a networked set of pbx's (each with it's own clock source) in my basement to prove to a former colleague of mine that you really can network pbx's together via T1's without one pbx being the master and the other a slave from a clocking perspective. This project will likely need to wait for my retirement. --- On Tue, 2/7/12, Hal Murray <hmur...@megapathdsl.net> wrote: > From: Hal Murray <hmur...@megapathdsl.net> > Subject: Re: [time-nuts] Why a 10MHz sinewave output? > To: "Discussion of precise time and frequency measurement" > <time-nuts@febo.com> > Received: Tuesday, February 7, 2012, 2:12 PM > > li...@rtty.us said: > > Thank goodness for that inertia.
