<h2>TCSM2A</h2>

<p>This feature is dealing with the 2nd generation transcoder/submultiplexer.
Together with the new half rate-related routing and switching in the BSC and
the TCSM2, it is possible to optimise utilisation of Ater PCM lines.</p>


<p>In full rate-only configuration, the maximum amount of
Ater channels is 96.</p>


<p>Half rate is not currently available in the 1.5 Mbit/s
PCM environment.</p>
