Dear Mark, Thanks for the file. In fact the 7204 & IOS was work for 10year+ when it pair w/ TimesSource3600 PRS. a few month before the TS3600 was dead and I replace it w/ TS3550.
So I was wondering, is there something difference in TOD between TS3600 & TS3550. Any suggestion?, I already replace 7204 and try a newer ISO ( from c7200-is-mz.122-11.T.bin to c7200-ipbasek9-mz.122-33.SRD8.bin) Thanks Bob Chan On Mon, Dec 8, 2014 at 6:57 AM, Mark Allwright <[email protected]> wrote: > > > -----Original Message----- From: Mark Allwright > Sent: Sunday, December 07, 2014 3:47 PM > To: [email protected] > Subject: Re: [time-nuts] GPS, NTP, and Cisco routers... > > Hi Bob. > > Here is a copy of the application note. > > I stopped using Cisco routers as my primary NTP sources some time ago > (years).
