A. combinerType

This parameter specifies the type of combiner used to connect the cells Base

Radios to the antenna. The options are hybrid and cavity. The MC-Series OPM

system is similar to a cavity type combiner physically but it does not have the

same frequency limitations as the cavity combiner that this parameter is used

for.

2.3.3 Recommended Datafill Parameters

The following parameters need to be set differently than what is currently set with

Motorola BR. These settings are not required but recommended for best

operation.

A. PCC

The power control constant is broadcast on the BCCH and is used by the MS

to calculate a target value for its transmit power. For Indoor Pico and Micro-Cell

applications this value will vary depending upon the RF environment (i.e., if

used outdoors the value will be quite different from an indoor scenario). For the

MC-Series OPM system, the setting of this parameter depends on what is

connected between the MC-Series OPM system and the antenna. The default

value should be calculated in accordance with Motorola guidance detailed in

the Datafill Parameter Guide. Lowering this parameter forces the mobile to

operate at fairly low Tx level thus conserving battery life. In cases where the

MC-Series OPM system is connected to a DAS, the gains and losses of the

paths should be taken into consideration. Additionally the level of uplink

interference should be considered when determining this value.

B. Pto (transmit power)

The Cells outbound transmit power referenced at the output of the RF

Distribution System Antenna Port. It is used as a reference point value when

computing the link budget of the system. RadioFrame Networks recommends

that the value of this parameter be set appropriate to the TOR output power,

which is determined by the defaultTxPower parameter (see below).

2.3.4 rxTxGain = 0

This parameter is the difference in gain between the receiver and transmit

antenna paths expressed in dB. The MC-Series OPM system does not use this

parameter directly.

2.3.5 defaultTxPower

Note: Refer to release notes for the proper range

information.

This is the average output power of the PA, measured at the RF connector of the

BR. For the MC-Series OPM system, this parameter can be used to adjust the

output power of the system. The gain at the shelf is fixed and cannot be altered.
