Mop Cut Over Process


Published on

The presentation will focus on overview of a majority of processes required for the FOA Cutover and on-going Cluster Cutovers. As a result of the process development, detailed Methods of Procedures (MOP) were created which will provide a step by step guidelines in the execution of the processes.

  • The Coordination Team consists of Cingular and Ericsson Project Managers with Cingular as final decision maker.The Coordination Team will include escalation directions, review of alternative solutions or backup plans in the event Cut-Over is not feasible as scheduled within the maintenance window. After Site Readiness is accepted, Ericsson to coordinate BTS delivery and scheduling of resources, etc. as part of the Sch’d Site Cutover. Pre-Checks will verify that cables, floor space, are still available as detailed in the FEED package and site walk that was performed at RFS notification. The Site Cut-Over includes activities at the BSC and MSC, Transport (T1s transferred), etc. Upon initial confirmation that Green Light Test is successful on WLS, cell tech to perform E911 test calls/sector. Site Cut-Over includes E911 P2 compliance
  • Side By Side - Available floor space to install RBS without affecting service. Interface cables may or may not be required to swap over from Nokia RBS or new cables (RF/T1/E911) are installed. Temporary Move – Nokia RBS will be relocated due to floor space requirements for the Ericsson RBS. Nokia RBS will be moved in area that will permit cables to be re-connected as afallback in the event that Ericsson RBS is not able to be cut-over. Formerly considered as a “Hot Slide” but due to anchoring system, Nokia RBS will have to be powered down. RIP – Requires that Nokia RBS be deactivated and removed before Ericsson RBS can be installed. This requires longer outage. COW/COP – Cell On Wheels/Cells On Pallet
  • Pre installation Site Walk down will consist of Ericsson and NAVL (transportation resource) with the objective of identifying any site readiness issues and to clearly identify site access issues (crane required, elevator sizing for T/I on multi-floor bldg, access road difficulty, etc.). Ericsson will record detailed site readiness conditions in order to minimize “show-stoppers” for the cutover process. The Logistic Center Process and Delivery Process is identified in another slide.
  • NOC to be contacted by Coordination Team to verify status of sites. Reference to approved MOP for the activities to be performed. T1 migration could consists of utilizing existing T1s or new tested T1s. Network Access reference to having IP address and passwords in order that Switch engineer will have access for changes/modifications during the cutover process. E911 Preparations – Field tech has TVW and PSAP information. Re-cabling from Nokia to Ericsson RBS is clearly identified
  • Develop Cut-Over Sequence – Based on the site readiness in [particular cluster to be cutover the the Coordination Team (Cingular,Ericsson, Bechtel, and others) will develop a site cut-over sequence. This process assumes that the installation steps for Side By Side have been completed, while other configurations may require additional work during the Maintainance window for installation efforts.
  • Trouble shooting requires prior coordination with equipment vendors, Ericsson, Cingular, Andrews, Intrado, Powerwave. The first line support is the initial step in identifying problems.
  • Before Fall back decision is approved, all technical support would have been investigated. Fallback requires that testing of Nokia RBS be performed, including E911 verification.
  • Pre Cut Activities Process developed by Ericsson RF Group.
