25 If the results of Step 18 indicate the antenna cable delay and elevation mask set are as
desired, skip to Step 26. Use the Edit Equipment command to set the length of cable
between the antenna and the TimeSource 3000 Shelf. This number should have been
recorded during installation. Use the same command to set the antenna elevation mask
angle.
ED-EQPT::GPS:<ctag>:::ANTCBLDLY=x,ANTELEVMASK=y;
x = antenna cable delay in meters (x = 0 to 330)
y = antenna elevation mask angle in degrees (y = 0 to 45) (see note below)
Note: The antenna elevation mask is that portion of the sky from which the TimeSource 3000
masks out satellite signals, measured from the horizon to the desired angle of elevation. For
example, if the sky is obstructed below 20° elevation, signals received from below that
elevation may have reflections or other anomalies. Masking those signals may allow the
receiver to acquire GPS signals more quickly and accurately. Factory setting is 0.
26 If not using the TOD output, skip to Step 27. Use the Edit Equipment command to set the
TOD output.
ED-EQPT::TS3000:<ctag>:::TOD=y;
y = TOD format (y = Cisco or NTP4)
27 Use the Edit Equipment command to allow or inhibit alarm conditioning on the outputs.
Inhibiting the alarm conditioning forces the TimeSource 3000 to continue to output valid
timing signals while in alarm. This may be useful when testing, troubleshooting, or in
installations where the outputs generated by the TimeSource 3000 may be better than the
alternative (for example, offices without additional holdover clocks in a distribution shelf).
ED-EQPT::TS3000:<ctag>:::ALMCOND=y;
y = alarm conditioning of the outputs (y = ALW or INH)
28 If not using Ethernet, go to Step 32. Use the Edit Equipment command while connected to
COM1, COM2, or the CRAFT port to set the IP address, subnetwork mask, and gateway
address for the current TimeSource 3000 unit, as required for proper operation in the
managed element network. (These parameters affect all Ethernet ports. The Ethernet port
should be closed and all users logged off before issuing this command.)
ED-EQPT::TS3000:<ctag>:::IPNE=a,IPSUBNET=a,IPGATE=a;
IPNE=a This unit's IP address in the form a.a.a.a (each a is an independent value of 0
to 255)
IPSUBNET=a Subnet mask in the form a.a.a.a (each a is an independent value of 0 to 255)
IPGATE=a Gateway IP address in the form a.a.a.a (each a is an independent value of 0
to 255)
