Metaswitch’s OCSS7 is a protocol stack implementing a set of SS7 and related SIGTRAN protocols. The stack is intended to be used in an Metaswitch Rhino JAIN SLEE environment with Metaswitch’s CGIN.

The current version supports M3UA, ITU-T SCCP, ANSI SCCP, ITU-T TCAP, and ANSI TCAP.

OCSS7 offers the following main features:

  • Communicates with Signalling Gateways using the SIGTRAN M3UA protocol

  • Communicates with IPSP using the SIGTRAN M3UA protocol

  • Communicates with a TCAP user application using the TCAP SPI interface (which is CGIN RA within Rhino)

  • Cluster deployment — The OCSS7 stack may be deployed in a cluster where multiple stack instances cooperate and represent a single SPC.
