b. Set the IP Port on which the base will receive STFP messages from the Communication
Manager.
c. Set the IP Address of the Communication Manager to which timing markers and
messages received from mobiles should be sent.
d. Set the IP Port of the Communication Manager to which timing markers and messages
received from mobiles should be sent.
e. Set the epoch size to match the same value configured on the neighboring radios and
reboot if necessary.
f.
Set the STFP slot delay as necessary. This number, multiplied by 125ms, represents the
slot delay allowed from when a timing marker is sent to the Communication Manager to
when a data message must be received from the Communication Manager. For most
cases the default value of 3 should suffice.
8. Go to the Ping Utility Menu (Under the Maintenance/Tools Menu).
a. Verify the Ethernet link using the Ping utility.
9. Begin sending STFP data.
10. Verify the TX LED illuminates and the radio begins transmitting over the air.

Set Up a PTP Base Unit
1. Install and configure a PTP Grandmaster Clock. The clock must be accessible to the Base Radio
through the Ethernet Link. The base may interface to an external Communication Manager using
the Ethernet Link; therefore, an external switch or router may be required.
2. Log in to the radio.
3. Go to the PTP Configuration Menu.
a. Choose the PTP Profile for the Base to match with the settings on the Grandmaster
Clock.
b. If Telecom profile is selected in step a, set PTP Unicast Master to the IP address of the
Grandmaster Clock.
4. Go to the System Configuration Menu.
a. Set the timing source to PTP and allow the radio to reboot.
5. Logging in again after the reboot, verify that the radio's Device Status is
on the Starting Information Screen. If not, enter 'A' to get a list of the current alarms and correct
the alarm condition.
6. Go to the STFP Configuration Menu (Under the System Configuration Menu).
a. Set the STFP radio ID from the default 0 (it's recommended).
b. Set the IP Port on which the Base will receive STFP messages from the Communication
Manager.
c. Set the IP Address of the Communication Manager to which timing markers and
messages received from mobiles should be sent.
d. Set the IP Port of the Communication Manager to which timing markers and messages
received from mobiles should be sent.
e. Set the epoch size to match the same value configured on the neighboring radios and
reboot if necessary.
f.
Set the STFP slot delay as necessary. This number, multiplied by 125ms, represents the
slot delay allowed from when a timing marker is sent to the Communication Manager to
when a data message must be received from the Communication Manager. For most
cases the default value of 3 should suffice.
7. Go to the Ping Utility Menu (Under the Maintenance/Tools Menu).
a. Verify the Ethernet Link using the Ping utility.
8. Begin sending STFP data.
9. Verify the TX LED illuminates and the radio begins transmitting over the air.
