 PA-MCX-8TE1-M, Cisco PA-MCX-8TE1-M, 8 port T1, E1 port adapter with a custom hardware-assist engine to support SS7 signaling
The Cisco IP Transfer Point (ITP) solution allows mobile operators to use a more manageable and cost-efficient IP network as transport for SS7 traffic. The Cisco ITP solution will complement or eventually replace existing SS7 networks built of signaling transfer points (STPs).
The Cisco SS7 Port Adapter (product part number PA-MCX-8TE1-M) is a fundamental part of the Cisco ITP solution, providing high-density, high-throughput connectivity to traditional SS7 devices. This port adapter is a specialized T1/E1 hardware device that can only be used for SS7 Message Transfer Part Layer 2 (MTP2) connectivity. It is only supported in the rsp-itpv-mz Cisco IOS® Software Release 12.2 MB images. Table 1 highlights the general applicability of the Cisco SS7 Port Adapter.
The Cisco SS7 Port Adapter is a singlewide port adapter designed to provide a full 8 port SS7 solution for the Cisco 7500 Versatile Interface Processor (VIP) and the Cisco 7204 VXR and 7206 VXR routers. The port adapter supports a maximum of 126 signaling links that can be distributed in any combination over the available eight physical T1/E1 ports.
The MTP2 of the SS7 protocol requires constant repetition Fill-In Signaling Units (FISUs) while no data is being transmitted. The port adapter complements the software implementation of MTP2 by repeating and filtering identical FISUs in hardware, freeing CPU resources and enhancing performance and throughput.
The RJ-48c ports are software configurable to support T1 or E1 (120-ohm) interfaces. A simple cable adapter for conversion to a 75-ohm coaxial cable interface is available. In T1 mode, each port can support up to 24 SS7 links for an aggregate data rate of 1.536 Mbps per port. In E1 mode, each port can support up to 31 SS7 links per port for an aggregate data rate of 1.984 Mbps per port. |
