Bsi (Base Station Identication); Monitor Before Data Transmit; Rf Frequency Bands - Futurecom PDR8000 Manual

6.2.8 BSI (B
ASE
PDR8000 can be configured to automatically transmit an audible signal (Morse code) over the
air that identifies the station by call sign (up to 20 alphanumeric characters). Each channel of
the PDR8000 can be configured to transmit a different Identifier (call sign).
The periodic interval between sending the ID signals is configurable. The configured interval is
used across all channels of the PDR8000. This functionality is not available for Receive-only
configurations.
6.2.9 M B
ONITOR
Configured on/off. This functionality is intended for use when connected via wireline to a data
system. Data applications typically create bi-directional traffic. In many cases data is sent in
one direction, and then an acknowledgement flows in the other direction. This means that both
transmit and receive paths are needed to have effective data communications. If the Monitor
Before Data Transmit option is enabled, then PDR8000 can assist the data system
infrastructure by giving it information to help it decide when to send data transmissions. When
this option is enabled, the PDR8000 monitors the receive frequency and notifies the data
infrastructure about co-channel user activity. This allows the data system to pause data
transmissions when other traffic exists on the channel, and to resume data transmissions when
the other activity has ended.
If the Monitor Before Data Transmit option is not enabled, then PDR8000 does not provide this
activity information to the data system infrastructure. The data system might then send out data
successfully, but be unable to receive the correspond acknowledgements due to other activity
on the channel. This results in data retries, and overall poor performance for data
transmissions.
6.3 RF F
REQUENCY
PDR8000 supports RF communications on VHF, UHF, 700 MHz and 800 MHz bands, as
summarized below:
•
VHF: 136 - 174 MHz
•
UHF: 380 - 430 MHz
•
UHF: 450 - 470 MHz
•
700 MHz**:
o Tx: 764 - 776 MHz
o Rx: 794 - 806 MHz, and 764 - 776 MHz to monitor direct subscriber-to-subscriber
activity
•
800 MHz:
o Tx: 851 - 869 MHz
o Rx: 806 - 824 MHz, and 851 - 869 MHz to monitor direct subscriber-to-subscriber
activity
There is a different model of PDR8000 for each of the above RF frequency bands. A specific
order code is available for each.
