Philipp Maier fdefbfac39 Transceiver: Log when sending of CLK indications begins
When the logging category TRXCLK is set to info osmo-trx prints a
logline that informs about the sending of clock indications. In practice
this those log lines are often used to identify that osmo-trx and
osmo-bts are running properly, so it would be helpful, even in
productive use, if there would be an information in the log that the
sending of clock indications has begun. However, the regular printing of
the clock indication log line would soon flood the log. So, lets have an
addional log line that logs only once when the transceiver starts and
quickly informs at loglevel NOTICE that clock indications are now sent.

About OsmTRX

OsmoTRX is a software-defined radio transceiver that implements the Layer 1 physical layer of a BTS comprising the following 3GPP specifications:

  • TS 05.01 "Physical layer on the radio path"
  • TS 05.02 "Multiplexing and Multiple Access on the Radio Path"
  • TS 05.04 "Modulation"
  • TS 05.10 "Radio subsystem synchronization"

OsmoTRX is based on the transceiver code from the OpenBTS project, but setup to operate independently with the purpose of using with non-OpenBTS software and projects, while still maintaining backwards compatibility with OpenBTS when possible. Currently there are numerous features contained in OsmoTRX that extend the functionality of the OpenBTS transceiver. These features include enhanced support for various embedded platforms - notably ARM - and dual channel diversity support for the Fairwaves umtrx.
