XPort2001 Four-Port Serial I/O Module

The XPort2001 is an intelligent communications controller targeting high-performance yet low-cost communications applications. The XPort2001 supports fully channelized HDLC and transparent protocols over four software-configured T1/E1/J1 interfaces, with CSU/DSU support and optional Signaling System 7 (SS7).

The XPort2001 packs maximum performance and flexibility into an industry-standard conduction-cooled PMC module form factor. Coupled with X-ES supplied software, customers can install the XPort2001 on standard cPCI and VME platforms or custom motherboards that support PMC sites. The XPort2001 can also withstand industrial temperatures, with an operating range of -40°C to +85°C.

The MPC8270 processor core can deliver 885 MIPS of processing power at 450 MHz. Alternatively, the XPort2001 can be configured as a peripheral device for an ultra-low-power solution by disabling the CPU core.

The XPort2001 will help drive both cost and power consumption down. Since the PCI bridge is integrated on chip, the XPort2001 requires up to 40% less power and costs up to 30% less than other four-port designs based on other processors.

A Wind River VxWorks BSP and driver package are available. X-ES also offers Asterisk support for the XPort2001 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.
