This chapter describes the components of the SS7 protocol stack. Length indicators allow Level 2 to determine what type of signal unit it is receiving, and how.
SIGTRAN is the name, derived from signaling transport, of the former (I) working group that produced specifications for a family of protocols that provide reliable service and user layer adaptations for. The SIGTRAN protocols are an extension of the SS7 protocol family. It supports the same application and call management paradigms as SS7 but uses an (IP) transport called (SCTP), instead of TCP or UDP. Indeed, the most significant protocol defined by the SIGTRAN group is SCTP, which is used to carry signaling over IP. The SIGTRAN group was significantly influenced by engineers intent on using the new protocols for adapting networks to the with special regard to signaling applications. Recently, SCTP is finding applications beyond its original purpose wherever reliable datagram service is desired.

SIGTRAN has been published in, under the title Framework Architecture for Signaling Transport. Also defines the concept of a (SG), which converts Common Channel Signaling (CCS) messages from SS7 to SIGTRAN. Implemented in a variety of network elements including, the SG function can provide significant value to existing common channel signaling networks, leveraging investments associated with SS7 and delivering the cost/performance values associated with IP transport.

SIGTRAN protocols The SIGTRAN family of protocols includes:. (SCTP),.
User Adaptation (IUA),. 2 (MTP) User Peer-to-Peer Adaptation Layer (M2PA),. 2 User Adaptation Layer (M2UA),. (SCCP) User Adaptation (SUA),. User Adaptation (V5UA),. / User Adaption (DUA), The provides the for SIGTRAN user adaptation layer messages across an IP network. It is described in,.
IUA provides an SCTP adaptation layer for the seamless of user messages and service interface across an IP network. Some users that it supports are. It is specified in. V5UA provides an SCTP adaptation layer for the seamless backhaul of V5.2 user messages and service interface across an IP network. It is a variation of IUA and is specified in. M2PA provides an SCTP adaptation layer for providing an SS7 MTP signaling link over an IP network.
