<strong>M2PA</strong> <strong>V1.0</strong><br />
IETF RFC 4165<br />
MOD 100 1093<br />
The MTP-L2 User Peer-to-Peer Adaptation Layer (<strong>M2PA</strong>), protocol module handles<br />
transport of Signaling System No. 7 Message Transfer Part Level 3 (MTP-<br />
L3) signaling messages over Internet Protocol (IP) using the services of the<br />
Stream Control Transmission Protocol (SCTP).<br />
The <strong>M2PA</strong> protocol module is suitable for supporting<br />
the transfer of messages from MTP-L3 protocol layer<br />
over SCTP. This enables the use of IP infrastructure<br />
for transport of SS7 signaling while maintaining the<br />
network topology of 2G and 3G networks.<br />
The <strong>M2PA</strong> protocol module is fully integrated in<br />
<strong>Tieto</strong>’s Signaling Software products.<br />
