Communication processors handle SS7

The MUSYCC M28480 and M28481 HDLC/SS7 multichannel synchronous communications controllers format and de-format 512 bidirectional HDLC/SS7 channels, and also provide for running Message Transfer Protocol (MTP) 1 and 2 in hardware. The chip enables networking equipment to terminate both data and signaling system 7 (SS7) traffic using the high-level data link control (HDLC) protocol.

The 23-mm-square PBGA484-packaged processors include a software convergence layer between their drivers and Trillium signaling software, creating a seamless application development system. The chips have one PCIe single-lane endpoint or one PCI bus interface, and include eight serial interfaces supporting mixed data rates including T1/E1/T3/E3, HSSI, and 8.192 to 32.728-Mbit/s TDM modes. (Ea/10,000: M28480 (PCI), $149.60; M28481 (PCIe), $159.60samples available now.)
