Course Details

Originally designed for TDM based transport, SS7 is the foundation of signalling within PSTN and PLMN networks. This course will catalogue the operation of SS7, both from an architectural and procedural perspective. Key focus will be placed on the operation of the MTP lower layers, as well as analysis of SCCP and ISUP. In addition, this course will also focus on the transport of SS7 across IP based transport networks. As part of this, the Sigtran User Adaptation layers will be examined, as well as the operation of SCTP.
