  • Message Transfer Parts: MTP1 characteristics2:43

    Describe MTP layer one as the physical layer, providing the link between network nodes via E1, with 32 timeslots per E1, and timeslot 16 for signal and 0 for synchronization.

  • Message Transfer Parts: MTP2 characteristics2:32
  • MTP2 Signalling Units - MSU, LSSU, FISU0:44
  • MTP2: FISU2:21

    Configure MTP2 FISU signaling to monitor signaling links by periodically sending fill-in signaling units, awaiting acknowledgments, to detect link problems using a predefined 150 milliseconds interval.

  • MTP2: LSSU3:10
  • MTP2: MSU2:25
  • Signal Unit Field: LI9:21

    Explain the signal unit field LI and its parameters for fill in signaling unit, link state signaling unit, and message signaling unit, focusing on the six-bit length indicator.

  • Signal Unit Field: Flag2:53
  • Signal Unit Field: BSN, BIB & FSN2:27

    Explain how the backward sequence number (BSN) and forward sequence number (FSN) track signaling messages, and how the backward indicator bit signals positive acknowledgement when delivered correctly.

Description

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.

SS7 is a key element in the control plane of fixed and mobile networks and in Intelligent Network scenarios. It facilitates communication between SS7 hosted ‘applications’ enabling end-to-end service delivery. This course provides a comprehensive description of SS7 protocols, functions and procedures.

The drive towards all-IP networking necessitates the transport of SS7 protocols over an IP domain. This course provides a thorough explanation of how this is achieved using the SIGTRAN ‘toolkit’.
