<h2>Before you start</h2>

<p>Before you can enable GPRS in BSC, you first need to create and connect
the Packet Control Unit (PCU) to the BCSU. Next, you establish the Gb interface
between the BSC and SGSN. For the Gb interface you may also need dedicated
ETs. Finally, you need to create the Routing Area and enable GPRS on a cell
level.</p>

<dl class="note-notification">
<dt class="note-caption">Note</dt>
<dd>The BCSUs have to have the same number of PCUs even though the PCUs
may not all be needed. For BSCE and BSCi, the maximum is 8 working and 1 spare
PCU per BSC, and for BSC2A, BSC2E and BSC2i the maximum is 16 working and
2 spare PCUs per BSC. For BSC3i, the maximum is 24 working and 4 spare logical
PCUs per BSC. </dd>

<dd>A logical PCU is an entity handling the same functionality in BSC3i
as a physical PCU plug-in unit in the other Nokia BSC models.</dd>
