Parameter

Description

Operator ID

A unique identifier of the network. The same Operator ID must be defined for all Base Stations/Micro Base Stations in the network, and it should not be used by any device belonging to another network in the same area.

The Operator ID consists of 3 groups of up to three digits each, where the range for each group is 0 to 255.

In the modular Base Station, the Operator ID parameter is used by all AUs. Updated value of the Operator ID is applied for each AU after resetting the AU (or after resetting the NPU, which causes reset of all AUs). In the Micro Base Station, a change in the value configured for the Operator ID is applied only after reset.

Cell ID

A unique identifier of Base Station/Micro Base Station. The same Cell ID should not be used by any other device belonging to the network.

The Cell ID consists of 2 groups of up to three digits each, where the range for each group is 0 to 255.

In the modular Base Station, the Cell ID parameter is used by all AUs. Updated value of the Cell ID is applied for each AU after resetting the AU (or after resetting the NPU, which causes reset of all AUs). In the Micro Base Station, a change in the value configured for the Cell ID is applied only after reset.

ATPC Support

The ATPC Support parameter controls whether the ATPC algorithm should be used to determine current optimal transmit level for each SU served by the modular Base Station/Micro Base Station.

The ATPC algorithm should always be enabled. The option to disable it is available to support certain tests. After each reset, the modular Base Station/Micro Base Station boots with the ATPC enabled, disregarding its status before the device was reset.

Optimal uplink RSSI (dBm)

The Optimal Uplink RSSI sets the target level at which all transmissions should be received by the AU-ODUs for optimal performance.

The available range is from -80 to -74 (dBm).

You can see the actual value of the Optimal Uplink RSSI in the Air Interface page of each AU/Micro Base Station.

Duplex Mode
(Current and Configured)

The operation mode of the system: TDD or FDD.

In the current release only TDD Mode is supported and the Duplex Mode should not be changed.

A change in the configured Duplex Mode is applied only after reset.

Duplex DL/UL Ratio (%)
(Current and Configured)

Defines the ratio of transmit (Down Link) time to receive (Up Link) time, in percents. (Applicable only for TDD Duplex Mode).

The available values are:

• 65-35

• 60-40

• 55-45

• 50-50

• 45-55

• 40-60

• 35-65

When Sub-channelization is enabled (Minimum Number of Sub-Channels is other than 16), some DL/UL Ratios are not supported for certain combinations of Bandwidth, Minimum Allocation (configurable only via Telnet) and Maximum Cell Radius:

• For 3.5 MHz bandwidth and AU Minimum Allocation of 5 Symbols, DL-UL Ratios of 65-35 and 60-40 are not supported, regardless of Maximum Cell Radius. DL-UL Ratio of 55-45 is not supported for Maximum Cell Radius of 19 km and higher.

• For 3.5 MHz bandwidth and AU Minimum Allocation of 3 Symbols, DL-UL Ratios of 65-35 and 60-40 are not supported, regardless of Maximum Cell Radius. DL-UL Ratio of 55-45 is not supported for Maximum Cell Radius of 42 km and higher.

• For 5 MHz bandwidth and AU Minimum Allocation of 5 Symbols, DL-UL Ratio of 65-35 is not supported for Maximum Cell Radius of 30 km and higher.

A change in the configured Duplex DL/UL Ratio is applied only after reset.
