page 1
17. Use a 12-channel basestation in areas of high traffic capacity. Cell subdivision
is appropriate when it helps to improve coverage where the loop resistance exceeds 100
ohms or when a DMC cannot support more than two 12-channel units.
Note:
Use Table 25: Cell re-engineering on page 113 only for user types H&W and H. For user
type M see A mix of users with and without wired telephones in a cell on page 115.
Determining cell re-engineering
1. Locate the estimate for users in the first cell.
In the example shown in Table 23: Example of a completed estimate table on
page 113, the handset estimate is 11.6.
2. Determine the telephone types in the first cell.
In the example shown in Table 23: Example of a completed estimate table on
page 113, the telephone type is H&W.
3. Locate the telephone type column in Table 23: Example of a completed estimate
table on page 113.
In the example H&W is the users with both a handset and a wired telephone.
4. Find the handset estimate range in Table 25: Cell re-engineering on page 1
13.
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-channel basestation.
In the example From 0 up to 20, division is not required.
6. Repeat the above steps to determine the required number of cells that need
subdivision, except for telephone types M. For M see
A mix of users with and without
wired telephones in a cell on page
115.
7. Transfer the results into the Provisioning records.
Cell division requirements in special cases
This section describes how to determine cell division in the following special cases where:
1.
no office information is available; and,
2. there is a mix of handset users with and without wired telephones.
