For detailed information about the appropriate description of the various supported CPUs and VMs, refer to Terminology.
The SCCP User Adaptation (SUA) layer is a client/server protocol to support the transport of SS7 SCCP messages over SCTP/IP. The Signaling Transport (SIGTRAN) working group within the IETF standard organization developed this protocol.
In SUA terminology, registration is a procedure used to assign a Routing Context (RC) to a routing key. However, SUA registration leaves the RC in a DOWN state, meaning that the Signaling Gateway (SG) cannot process traffic yet for this RC. The RC is later used in an activation procedure, where an application is ready to process traffic corresponding to the respective routing key.
This two step registration and activation process is unlike many other applications where registration and activation happen simultaneously, as for example, with CIC UA.
An SUA SCTP server must be configured on a Routing CPU or VM before an SCTP Association can be created and registration requests can be received.
Note
SUA supports IPv4 addresses, IPv6 addresses, and hostnames.
Hostnames must resolve to either IPv4 or IPv6 addresses, or a combination of both address types.
Note
The SP2000 does not support IPv6.
