Clock Synchronization
Timing over packet for 2G BTS (Not Co-located with 3G Node-B)
The RAN synchronization is based on Timing Over Packet following standard IEEE 1588. One ToP master clock can synchronize up between 800 NE. The ToP will be connected to CE Router as 1+1 ( Active and Standby ) as shown below.
The O&M connectivity for ToP as below. The Symmetricom O&M connectivity will be a single connection to COMIS router as hardware limitation.

Clock Synchronization
Timing over packet for 2G BTS (Co-located with 3G NodeB)
Synchornization to other system modules can also be done based on IEEE1588-2008, provided other system modules support IEEE1588-2008 slave functionality. ToP Engineering rule should be taken into
account.
1. Current 2G GSM - through PCM E1
2. 3G WCDMA Timing over Packet (TOP)
3. LTE - GPS

2G/3G Modernization
GSM
1. Existing Dump to be used as a reference
2. Existing Physical site database as a reference
3. 2G Parameter/new frequency plan in case new configuration is needed (for
example TRX upgrade), For 3G Parameter/SC plan in case new configuration is
needed (for example Carrier upgrade)
4. A-bis timeslot mapping generated by the planning team to be followed
5. XML creation to be done in a case the site configuration changed (existing
parameters to be used if no upgrade)
6. the above XML to be sent to CM team for implementation
7. Site integration report received from NI after integration
8. NPO will check the parameter consistencies, health check (alarms), and initial KPI
9. Post modernization Drive test to be done to verify the hardware and swap feeders
10.KPI reports to be submitted to STC optimization for acceptance
11.Site accepted and passed to Managed Services

2G/3G Modernization ( Swap from Other Vendor)
Final Swap (Cold Swap) :
1.All NSN BTS sites with required E1s and BSCs /RNC are deployed, commissioned and integrated.
2.All routing plans in the MSC verified and found to be correct.
3.The RF parameters for all swap BTS sites have been matched up with the existing RF settings in old vendor network, so that the two networks have same RF parameters after swap.
4.Drive test vehicles are available
Activities :
1. Disable old BTS sites by giving commands.
2. Remove all Jumpers from Old BTS by Locking the TRX.
3. Connect the NSN BTS to the Existing Feeder line with new jumpers.
4. Once all six cables are properly connected, Powered on the NSN Flexi Modules.
5. Connect the E1 and check OMU become functional.
6. Unlock the DTRX.
7. Display the status of the BTS at the GNSC, and confirm that all devices are Installed and
Operational.
8. Drive test teams should start the activity after the site is On Air

2G/3G Modernization ( Swap from Other Vendor)
HOT SWAP :
In case of HOT SWAP installation and commissioning of NSN BTS to be done during the outage period only.
However following pre-requisites needs to be confirmed:
1. Availability of Manpower and Tools.
2. Installation material availability.
3. Confirmation of site Access during outage time.

Modernization Fall Back Procedure
2G
1. Save the latest dump
2. Extract the site parameters / configurations by clicking the Backup plan in
NetAct using XML format before deleting the site
3. Save this file
4. During fall back, re-run this XML file to re-create the site
5. Re-create A-bis and ADJx based on the dump
6. The field team must retrieve the old commissioning and A-bis plan
3G
1. There is no parameter change during modernization
2. The same parameters exists in NetAct so only equipment change over
to be done

Add New LTE
1. Existing Physical site database as a reference in case of collocation
2. Parameter planning and creation
3. XML creation
4. XML to be sent to CM team for implementation
5. Site integration report received from NI after site integration
6. NPO will check the parameter consistencies, health check (alarms), and initial KPI
7. Drive test to be done to verify the hardware and swap feeders
8. Site locked and to be unlocked for testing purpose
9. KPI reports to be submitted to STC optimization for acceptance
10.Site accepted and passed to Managed Services
