7.2.3 Network Listen and Frequency Correction
1) If not already logged in, login to the NOS Client with a user name that has Full
Access to the required AP.
2) Select the AP object within the managing AP Management Service, AC Detail and
Site. Select its 3GAP Time package, then wait a few seconds for the Up Time
attribute to update. Verify that this is at least 1200, which is 20mins, before
continuing. This ensures the frequency crystal has had some time to warm up and
achieve a degree of thermal stability prior to checking if it needs any frequency
correction. If necessary, wait until the Up Time passes 1200 seconds.
3) An AP must be locked to execute a Network Listen scan. Right-click the AP object
and select Lock, then wait until a small padlock symbol is shown against the AP
icon.
4) To execute a Network Listen scan, right-click the AP object, select Actions and
then select Start Sequential NWL Scan.
5) When the scan is complete, view the results and verify there is some radio activity
detected, and ideally some neighbour cells. This will confirm the radio is working.
6) Only if a suitable macro neighbour has been detected, a correction can be applied
to ensure that the oscillator frequency is correct. Select Actions and then select
Apply Frequency Correction.
Note: Assuming there is a suitable macro neighbour, this should be repeated
approximately 24 hours after the AP is brought into service. This will allow
time for the oscillator crystal to stabilize, at which time the frequency
correction should be re-applied.
7.3 Bring the AP into Service
Once the AP has the latest software image, any additional configuration is complete and
any frequency correction has been applied, it is ready for service.
In most cases, a correctly pre-provisioned AP will start providing service once it has
obtained its configuration from the NOS Server. These steps are only necessary when an
AP is not yet enabled for service, or has been locked to apply additional configuration. An
AP that is administratively Locked will have a small padlock symbol next to the AP icon.
1) To bring the AP into service, right-click the 3G AP object in the NOS Client and
select Unlock. The padlock symbol next to the 3G AP icon will be removed.
2) If the installation engineer is still on site, the engineer should make CS and PS test
calls to verify the AP is providing service.
