XPort2000

Freescale MPC8280-Series Processor-Based Four- or Eight-Port T1/E1/J1 PMC Module

The XPort2000 is an intelligent communications controller targeting high-performance yet low-cost communications applications. The XPort2000 supports fully channelized HDLC and transparent protocols over eight software configured T1/E1/J1 interfaces, with CSU/DSU support and optional Signaling System 7 (SS7). The XPort2000 packs maximum performance and flexibility into an industry-standard PMC module form factor. Coupled with X-ES supplied software, customers can install the XPort2000 on standard VME and cPCI platforms or custom motherboards that support PMC sites.

For the system designer, the XPort2000 will help drive both cost and power consumption down. Because the PCI bridge is integrated on chip, the XPort2000 requires up to 40% less power and costs up to 30% less than other four-port designs based on other processors. The XPort2000 realizes the full potential of the MPC82xx (PowerQUICC II™) series by supporting a low-cost MPC8270 four-port solution and a cost scalable MPC8280 eight-port solution. With the MPC8280, ATM over T1/E1 and Inverse Multiplexing ATM (IMA) can be realized as well. For processor-intensive and power-sensitive solutions, the MPC8270 (4-port solution) or MPC8280 (8-port, IMA solution) are supported, packing in maximum performance for your telecom solutions.

A VxWorks BSP and driver package are available. X-ES also offers Asterisk support for the XPort2000 through a driver implementing the Zaptel interface on Linux. This allows bridging the Asterisk PXB/VoIP system to a telecom network through a T1/E1 connection.
