The XPort2140 supports fully channelized HDLC and transparent protocols over 8 software configured T1/E1/J1 interfaces, with CSU/DSU support and optional Signaling System 7 (SS7). Up to eight of the T1/E1/J1 interfaces can be brought through the front panel, and the remaining can be brought through the backplane I/O. Data can be processed by the MPC8540, and then routed to either the PCIe or Gigabit Ethernet AMC fabrics.
Hot Swap support allows XPort2140 to be installed and removed from a live system.
