The MARBEN™ SONET/SDH Protocol suite includes fully compliant implementations of the TL1 Translation device and of the File transfer Translation device. These components that are fully integrated with the underlying protocols provide small foot print and best performances thanks to on-the-fly conversions. The T-TD and FT-TD functions are usually located in the GNE itself.

The MARBEN™ implementation of a FT-TD gateway, in conformance with [NSIF-033-1999]. mainly consists of an FTAM responder and an FTP client, allowing FTAM initiators to store or retrieve files from an FTP server. This gateway is one of the tools designed to manage SONET NEs, most of them implementing today a FTAM initiator function, from a TCP/IP access DCN. Indeed, a FT-TD is the usual companion of a T-TD, allowing to trigger a file transfer from a remote NE, such commands are typically sent to the remote NE through a T-TD.
