Do not connect more than two 12-channel basestations to a DMC card. Two 6-channel
basestations can also be attached to a DMC serving two 12-channel units. If loop resistance
exceeds 100 ohms, external power must be used.
The cell re-engineering process
The cell re-engineering process involves:
1. Estimating traffic within a cell on page
107.
2.
Separating the coverage area and recording the number of offices on page 108.
3. Creating an estimate table on page 108.
4. Calculating the number of users inside the cell with an office on page 110.
5. Calculating the number of users with an office outside the cell who walk into the
cell on page 109.
6. Calculating the number of users without an office on page 110.
7. Totalling the estimate for users in a cell on page 1
11.
8.
Calculating the data for all remaining cells on page
112.
9.
Creating a table to document telephone types in a cell on page

Estimating traffic within a cell
Modify the previous deployment procedure to adjust the estimated number of users.
To carry
out this procedure:
• Determine the number of handset users with an office within each cell.
• Determine how many of these users have wired sets.
• Determine how many users without an office are normally in each cell.
Some users have both wired and handset telephones; other users rely on handsets only.
Re-engineered cells for high traffic areas are represented by an adjusted estimate for the two
groups: handset and wireless, and handset only. Use the adjusted estimate to determine
whether the cell sizes, indicated by the earlier deployment procedure, can handle the telephone
traffic.
If the traffic handling capacity of the cells is not adequate, use 12-channel basestations and
subdivide them into smaller cells to ensure the traffic is handled properly in accordance with
these instructions.
