These release notes describe the features and caveats for Release 2.2(B) of the Cisco SS7 Interconnect for Access Servers Solution. The following sections list the contents of this document and describe the solution and its components.
These release notes describe the following topics:
The Cisco SS7 Interconnect for Access Servers Solution is a distributed system that adds SS7 signaling interfaces to large ISP POPs. SS7 interfaces are connected to the PSTN using the same signaling technology as a PSTN switch. The Cisco SS7 Interconnect for Access Servers Solution consists of the Cisco SC2200, the Cisco Signaling Link Terminal (SLT), and network access servers (NASs). The Cisco SS7 Interconnect for Access Servers Solution turns a POP into an end-office switching system in the PSTN, allowing direct peer-to-peer signaling connectivity. The POP, as a switch, connects directly to the rest of the network as a peer.
Figure 1 shows a network that connects a PSTN carrier to an ISP POP using the Cisco SS7 Interconnect for Access Servers Solution.
