<dd>The NSEI has to be, and the NS-VCIs are recommended to be, in line with
the SGSN side, when the IP sub-network is used.</dd>
</dl>


<p>With the Nokia SGSN, you can only create one NS-VC between the PCU and
the SGSN. If the SGSN supports more IP endpoints, the system will create several
IP endpoints to the remote end. The maximum number of local endpoints is one
and remote endpoints is four. </p>


<p>Before the system can initialise the Gb interface for the NSEI you must
configure the NS-VCs (that is, the IP endpoints) to the remote end (SGSN)
as well. </p>


<a name="jan125162228" shape="rect"></a>
<dl class="note-notification">
<dt class="note-caption">Note</dt>
<dd>The remote IP address parameter determines, whether the local IP address
that is used is of the IPv4 or IPv6 type. The remote and local ends of the
NS-VC must use the same address type. Both address types can be simultaneously
configured to the PCU. </dd>
</dl>


<p>If you use the remote host name parameter instead of remote IP address,
the PCU will use which ever address type is configured to it. If both types
are configured, IPv4 is the default type. </p>


<ul>
<li><p>Create the network service virtual connection (NS-VC) in the
case of a static IP connection (FWC).</p>

<dd>The NSEI has to be, and the NS-VCIs are recommended to be, in line with

</dl>


<p>If you want to use load balancing between remote IP endpoints (NS-VCs),
or you want to use different IP endpoints for signalling and data traffic,
create more remote IP endpoints (NS-VCs) with FWC. The maximum
number of local endpoints is one and of remote endpoints is four. </p>
