<h2>Impact on transmission</h2>

<p>No impact in the case of Gb over FR.</p>


<p>If Gb over IP is employed in connection with EQoS, the
IP transmission network must support DiffServ. PCU sets DSCP values for IP
transport layer. For Uplink LLC PDUs, the values are determined by Traffic
Class, THP and ARP. The operator can set the values via PRFILE.</p>


<p>See <em>Interoperability with other SW products</em>
for details. See also <em>Gb over IP System Feature Description</em>
and <em>PRFILE and FIFILE Parameter List</em> in BSC/TCSM
documentation.</p>
