Note:

1. If the station is to be configured as an omni-directional cell, specify the antenna

and feeder information in Sector 1.

2. The carrier transmit power is that measured on top of the cabinet after the station

is officially set up and running.

3. The standing wave ratio is that measured at the RF jumper connector (the end

connecting to the CDU or DFU or DDU panel) in the cabinet with a standing wave

ratio measurer.

For the cabinet configuration information, please specify in the

relevant spaces in Figure 1-1, Figure 1-2, Figure 1-3and Figure 1-4

the names of the boards and modules (use acronyms wherever

possible).

For the baseband subrack of the basic cabinet, specify in the

relevant space in Figure 1-2, (baseband subrack in Figure 1-1can

it can be ignored.

Additionally, Table 1-3also needs to be completed, which is to

make supplemental description of some of the boards or modules,
