Comparison to CTM2 might be apples to oranges, since it doesn�t
support �CambiumSYNC� and probably can�t power a 450m.
On price, another comparison would be the new modular Packetflux
SyncInjector just coming out, although the first version will not
have CambiumSYNC.
Lacking a spec sheet or a user guide, I wonder about some features we
get with CTM2 or SyncInjector:
- can you remotely enable/disable power and sync to each port?
- does it monitor current or power consumption per port?
- does it have remotely resettable fuses per port?
I know that after a storm, sometimes we have ports in a TRIP state
from overcurrent, but reset the electronic fuse and it comes back to
life.

Negative,
Notice the green ports in the front for making your direct
connections to a DC source.
This design works well for us since all of our sites now have a 29v
and 48v supply system.
When we add one of these to an older site for upgrade we will leave
the cmm4 for the 29v gear
and install the cmm5 for the newer 450i/m gear. As we swap out older
450 gear to 450i or M we will
just add more controller modules. Which is much less than paying
another 1800+ for a whole cmm4 or ctm2
I have one site that has 3 cmm4 and the 3rd is only using one port.
Keep in mind the idea is to move to more capacity at your own pace
without going back every 6months to upgrade.
All ports are gige with built in surge on each port. The CTM2 or the
Cmm4 has never failed me on protection.

All Ethernet gear has to have some surge protection
built in or it will not pass certain specs.
But you need replicable/expendable robust external
surge suppressors as the first line of defense.
If the surge suppressor is designed properly it will
not degrade performance.

Looks like a stealth product. Maybe WikiLeaks can
get us a spec sheet. David, can you post a photo of
your setup?
It looks like around $1000 street price for 4 ports,
plus a separate controller, plus a UGPS? Wowzers.
Compare to CTM2 from LMG which is 8 ports with
integral controller.
Can you get 2 of the 4-port modules, or 1 module and
a controller, in 1U rackmount? Are you using the
controller? Does it exist yet?
You mention surge protection, does that mean it has
integral surge protection like the CTM2? Downside
would be frying a whole $1000 unit if it takes a hit.
If you still use a separate surge protector, like
maybe Chuck�s APC shelf modules, does the double
surge protector degrade Ethernet performance?
The compatibility chart show it can work with 56V APs
like 450i/450m, as well as 29V APs like 450. I�m
assuming it�s whatever power supply you connect to
the module? As opposed to generating the appropriate
voltages internally from the 48V input?

If anyone is going 450m I would really suggest the
CMM5 line of products to go with it.
Takes all the guess work out of gps timing and surge
protection at the base or control point.
Also, its a long term solution for those needing high
capacity within highly dense areas.
Just got our first one in yesterday and love the new
modular design and stackable ports for up to
32 controlled ports from one controller.
