92 Site planningProcedure 26Determining cell reengineeringStep Action1 Locate the estimate for users in the first cell.In the example shown in Table 16 "Example of a completedestimate table" (page 91), the handset estimate is 11.6.2 Determine the telephone types in the first cell.In the example shown in Table 16 "Example of a completedestimate table" (page 91), the telephone type is H&W.3 Locate the telephone type column in Table 16 "Example of acompleted estimate table" (page 91).In the example H&W is the users with both a handset and awired telephone.4 Find the handset estimate range in Table 18 "Cell reengineering"(page 91).In the example, 11.6 falls within the From 0 up to 20 category.5 Determine if a cell requires division or uses a 12-channelbasestation.In the example From 0 up to 20, division is not required.6 Repeat the preceding steps to determine the required number ofcells that need subdivision, except for telephone types M. For Msee “A mix of users with and without wired telephones in a cell”(page 93).7 Transfer the results into the provisioning records.--End--Cell division requirements in special casesThis section describes how to determine cell division in the followingspecial cases.• Where no office information is available.• Where there is a mix of handset users with and without wiredtelephones.No office informationIf the location of the offices of users is not known, calculate the estimatednumber of handsets for each cell using this formula.Nortel Communication Server 1000SIP DECT FundamentalsNN43120-123 01.076 January 2009Copyright © 2008-2009 Nortel Networks.
