I believe the order is that you have to have a valid S1 connection, *then*
the eNodeB will try to turn on the GPS. If the GPS works, *then* the eNodeB
will start turning on the antenna ports.
If you take an eNodeB out of the box, plug in a GPS, log in to the
management IP, and look at the timing port, the unit will never ever ever
say that it has timing, or even gps-comm-status. It needs to be configured
enough, and cabled enough, to have a valid S1 signaling connection to the
EPC.
I've told telrad that some UI changes, like a simple command to tell us
where it is in the process between 'cold boot' and 'fully functional' would
be nice, as well as maybe some more descriptive statuses. 'timing
gps-comm-status NoS1Server' would be far more useful.
Or, you know, just decouple initiating the GPS device from having a valid s1
server.
Similarly, imagine this:
>show ran port
PORT OPERATIONAL ADMIN
NUM STATUS STATE
------------------------------
1 OutOfService-NoTiming InService
etc
Or:
>show ran port
PORT OPERATIONAL ADMIN
NUM STATUS STATE
------------------------------
1 OutOfService-NoS1 InService
Or maybe even:
>show ran port
PORT OPERATIONAL ADMIN ERROR
NUM STATUS STATE STATE
-----------------------------------------------
1 OutOfService InService NoTiming or NoS1
Or maybe couple it into show status device:
>show status device
general {
product-type COMPACT;
product-subtype ENB;
compact-model-type BreezeCompact3000;
}
inventory {
hw-ver "1 (CORE: E500MC v3.2)";
serial-number 95018308;
main-sw-ver 0606.04013;
backup-sw-ver 0600.02616;
running-sw MainSW;
boot-ver 2013.01.00014;
up-time 2016-07-21T11:07:27-05:00;
}
Service-prerequisites{
S1-signalling VALID;
Timing VALID;
Ran-ports VALID;
}
Or something like that.

It will also look like that if your S1 is down.

Did you follow the wiring diagram that came with the GPS to make the cable?
If so, they are fried. They require a standard Cat5 cable, not the one on
the diagram that seems to still be included with some antennas. That wiring
diagram was for a different radio platform, not the Compact and we have had
many operators follow it and kill their GPS. Telrad has been RMA ing any
that happened to. We went through our tock and removed those directions but
I suspect there are some floating around still.

We are putting up 2 new sectors and both of them have no GPS comms.
Any idea of what to look for? I have a hard time believing that both GPS
antennas are bad.
BreezeCompact> show timing
timing gps-comm-status Down
timing external-1pps-status NotExist

timing coordinates latitude ""
timing coordinates altitude 0
