28. April 2010: Example code on github
The GTH API example code (in C, Perl, Python and Erlang) is now on github. (It will also continue being available as .zip files.)
1. February 2010: Expanded C example code
The blog discusses the expanded C example code which now includes a C API for accessing the GTH (and also precompiled .exe files for Win32 machines).
2. November 2009: GTH 2.1 hardware is now shipping
GTH 2.1 hardware is now shipping in volume. GTH 2.1 has the same physical size and external interfaces as GTH 2.0 and the same software API. GTH 2.1 offers increased frame relay monitoring performance.
- Double the frame relay performance in narrow channel applications: up to 256 input timeslots (16Mbit/s) in up to 64 separate channels. (GTH 2.0 provided 128 timeslots)
- Double the frame relay performance in wide channel applications: up to 496 input timeslots (32 Mbit/s) in up to 32 separate channels. 496 input timeslots corresponds to every timeslot on every E1 at the same time. (GTH 2.0 provided 256 timeslots).
This increased capacity allows one GTH 2.1 module to monitor both directions of eight GSM Gb interfaces.
GTH 2.1 can run software image gth2_system_32a or later.
