<p>The system impact of Nokia EDGE is specified in the sections below.

<h2>Impact on transmission</h2>

<p>EDGE sets new demands on Abis interface transmission. The Abis interface
transmission data rate varies depending on the call type used. It is not sensible
to allocate fixed transmission capacity according to the highest possible
data rate for every traffic channel from the Abis interface but share common
transmission resources between several traffic channels.</p>


<p>The Dynamic Abis feature makes it possible to define common transmission
resources for EDGE capable TRXs situated in the same Abis ETPCM. This common
resource is called the Dynamic Abis Pool. There are fixedly allocated transmission
resources for Abis signalling links and traffic channels in Abis ETPCM as
before but extra transmission resources needed for EGPRS calls are reserved
from the dynamic Abis pool.</p>
