These release notes describe Cisco Signaling Link Terminal (SLT), which is designed to perform SS7 signal pre-processing for a Cisco Media Gateway Controller. The Cisco SLT consists of a customized Cisco IOS Release 12.0(7)XR image running on a Cisco 2611 router. These release notes are updated as needed to describe new features, memory requirements, hardware support, and related document changes.
Use these release notes with Cross-Platform Release Notes for Cisco IOS Release 12.0 on Cisco Connection Online (CCO) and the Documentation CD-ROM.
These release notes describe the following topics:
The Cisco Signaling Link Terminal (SLT) enables service providers to reliably transport Signaling System 7 (SS7) protocols across an IP network. The Cisco SLT uses the Cisco IOS SS7 Signaling Link Terminal feature set, providing reliable interoperability with the Cisco Media Gateway Controller. The Cisco SLT is responsible for terminating the Message Transfer Part (MTP) 1 and MTP 2 layers of the SS7 protocol stack. Using Cisco's Reliable User Datagram Protocol (RUDP), the Cisco SLT backhauls, or transports, upper-layer SS7 protocols across an IP network to the Cisco SC or Cisco VSC.
In combination with this application-specific version of the Cisco IOS software, the Cisco SLT hardware component leverages the widely deployed Cisco 2600 multiservice access router. The Cisco 2600 series, driven by a powerful RISC processor, provides the high performance required in complex networking infrastructures.
When used for Signal Link Terminal applications, the modular Cisco 2611 dual-Ethernet port router can be configured with dual serial as well as the multiflex interface cards. The E1 multiflex interface cards offer integrated DSUs while the T1 multiflex interface cards offer integrated CSU/DSUs. For additional flexibility, the multiflex interface cards can also be ordered with a dual-port drop-and-insert capability. All of these interface cards are Field Replaceable Units (FRUs).
The Cisco SLT supports only the SS7 MTP 2 serial protocol. Therefore, the serial interfaces cannot be configured for other protocols such as HDLC, PPP, X.25, LAPB, and Frame Relay.
The Cisco SLT functions as a component of several solutions currently under development. Participants in lab trials can obtain solution documentation from their Cisco representative. See the "Service and Support" section for more information.
