<h2>Impact on Network Switching Subsystem (NSS)</h2>

<p>The 2G SGSN supports both static and dynamic configuration of the IP
subnetwork. Furthermore, both the IP and the Frame Relay based Gb interfaces
can exist parallel in the same 2G-SGSN.</p>


<p>The operator must create an IP NS-VC into the 2G-SGSN PAPU by giving
the IP endpoint and weight parameters for the NS-VC. There can be max. four
IP endpoint pairs per NSEI in the Nokia 2G-SGSN but only one local IP endpoint
per NSEI.</p>


<p>There is a 2G-SGSN measurement type, NS-VC Data Measurement (012) for
collecting information on the amount of packets transferred via NS-VCs towards
the BSS. The counters are collected on NS-VC level and they replace the old
corresponding PAPU level counters 003017 and 003018.</p>
