[AFMUG] Benefits of CMM/CTM over packetflux modules

We have been deploying the packetflux stuff as primary sync solution. Other than the little bugginess with it, I'm very satisfied. We have a CTM that I think we paid 1700 bucks for, the night we deployed it, we took a lightning strike and lost a port, so we have an AP independently powered and

Re: [AFMUG] Benefits of CMM/CTM over packetflux modules

A CTM2 can power different types/voltages of radios in one chassis (24/48) and has internal DC/DC converters to handle this so that you only need to provide it +48V. With SyncInjectors, you will need to give them 24V to power 24V radios, or 48V to power 48V radios. This means you need separate

Re: [AFMUG] Benefits of CMM/CTM over packetflux modules

When I lived in Canopy land, I liked the Sync Injectors for the small form factor and low power. Great for little bitty installs. We never lost a port on a CMM4, ever. We did blow up a few sync injectors during thunderstorms. So if you don't want to worry about it, get the CMM4.maybe

Re: [AFMUG] Benefits of CMM/CTM over packetflux modules

I only moved from CTM2 to CMM4 rackmount stuff only because of price. CTM2 does have all the good stuff a cmm4 only wishes it had but as far as protection both are equal. I have both in the field and have steadily replaced most if not all CTM1's with CMM4 due to CRC and some port failures after

Re: [AFMUG] Benefits of CMM/CTM over packetflux modules

+1 for Adam and David. We have a blend of CMM4 and CTM2's. My plant techs love the CTM2's because of their simplicity and design. However, our CMM4's just work. Never have blown ports. CTM2's are prone to port failure and have management issues. On Tue, Oct 20, 2015 at 9:43 AM, David

The cmm4 has both 48 and 24 volt terminals you can provide both supplies or just one or the other. The diff from the CTM2 and cmm4 is the CTM2 has the built in dcdc converter to drop 48v to 24 but not the other way around for 24 to 48. cmm4 rackmount no switch is about $1800 MSRP and the cmm4

Re: [AFMUG] Benefits of CMM/CTM over packetflux modules

We have moved from the CTM2 to using Netonix switches. with pairs swapped for polarity, and the syncbox 12 or Parasitic on each AP as a backup to the built in sync on the 450s. On that note, people have had issues with the built in sync on the 450s, but at sites where we have installed 450s

Re: [AFMUG] Benefits of CMM/CTM over packetflux modules

How much is a rackmount CMM4 these days? Do you have to provide both 24V and 48V if you want to power each, or does it have internal DC-DC converters? On Tue, Oct 20, 2015 at 10:50 AM, Eric Muehleisen wrote: > +1 for Adam and David. We have a blend of CMM4 and CTM2's. My
