Parameter

Description

Chain Number
(Current and Configured)

The Chain Number is used as a unique identifier of a chain. All modular Base Stations or Micro Base Stations belonging to the same chain should be configured with the same Chain Number. The Chain Number can be used by a central management system to guarantee that certain limitations are met. For example, in each chain one, and only one device should be defined as Master.

In the current release, chaining is supported only in Micro Base Stations.

The range is from 1 to 1500.

The default is 0, indicating that a Chain Number is not configured yet. A valid Chain Number must be configured, and this number must be unique in the system to properly support central management of chaining.

GPS Protocol
(Current and Configured)

The GPS Protocol defines the communication protocol with the GPS receiver.

The available options are None, Trimble (for Outdoor GPS Receiver) and Symmetricom (for Indoor GPS Receiver).

Stop Tx After Hold Over Timeout

Upon losing the 1PPS clock from the GPS, or if the received clock is not considered accurate enough because the number of received satellites dropped below the minimum (two satellites), the local 1PPS clock will be generated using the available 16 MHz clock. After a certain time (defined by the Hold Over Passed Timeout parameters described below), it is assumed that due to clock drifts there might be interferences among sectors belonging to the Base Stations and sectors belonging to neighboring Base Stations. If the Stop Tx After Hold Over Timeout parameter is set to Enable, the Base Station will stop transmitting after this timeout (unless the unit has exitted Hold Over mode following proper reception of at least four satellites), to prevent interferences to the sectors belonging to other Base Stations. If it is set to Disable, transmissions will continue indefinitely, at the expense of potential interferences to sectors belonging to other Base Stations.

Hold Over Passed Timeout (min)

This parameter defines the Hold Over timeout, after which there might be interferences to other sectors. When the Stop Tx After Hold Over Timeout is enabled, transmissions will stop after this timeout. When the Stop Tx After Hold Over Timeout is disabled, this timeout indicates that there might be interferences to neighboring sectors.

The range is from 0 to 2880 (minutes).

Time Zone Offset From UTC

This is the offset of the local time from UTC (Coordinated Universal Time).

The range is from -12:00 up to +13:00 in 30 minutes resolution. The format must be either -XX:YY or +XX:YY where YY is either 00 or 30.

Daylight Saving Status

The Daylight Saving Status parameter is used to enable or disable the daylight saving feature using the following Daylight Saving Start Date, End Date and Advance Factor parameters.

Daylight Saving Start Date

When Daylight Saving is enabled, this parameter defines the date for starting the daylight saving feature. At the beginning of this date (midnight at the beginning of this date), the clock will be advanced by the amount of hours specified by the Daylight Saving Advance Factor (see below).

Use the format dd:mm to define the date and month at which to start activating the Daylight Saving feature.

Daylight Saving End Date

When Daylight Saving is enabled, this parameter defines the date for ending the daylight saving feature (at "Daylight Saving Advance Factor" hours after midnight at the end of this date).

Use the format dd:mm to define the date and month at which to end activating the Daylight Saving feature.

Daylight Saving Advance Factor

When Daylight Saving is enabled, this parameter enables configuring the amount of time by which the clock should be advanced during the daylight saving period.

The range is from 00:00 to 04:45 (hours) in steps of 15 minutes.
