This is a four-port STM-1 interface card by Xalyo Systems.  It is based around an early Wintegra WinPath processor. _Unfortunately_ it can only do ATM and POS (packet-over-SONET), but doesn't have any support for channelized STM-1 (e.g. transport of E1/PDH over SDH).

The card is in a mezzanine carrier format, but using an adapter such as the XS-PCIE, it can be used in a normal PCIe slot.

* Wintegra WinPath WIN787FPC-200B1 network processor (attachment:WIN787.pdf)
11
* PMC S/UNI 155 TETRA PM-5351-BGI _Quad 155 Mbit/s ATM and Packet Over SONET Physical Layer Device_ (attachment:PM5351.pdf)

This is a carrier board for the mezzanine form factor of the XS-155.  It contains a PLX PEX8112 PCI to PCIe bridge (attachment:PEX8112.pdf), so that the carrie board can be plugged in a modern PCIe slot.
