DIGITAL CROSS-CONNECT |
摘要 |
A digital cross-connect (DXC) (10) comprises: a plurality of ports (30-100) for receiving/outputting signals and switching and switching means (20) for selectively cross-connecting signals applied to one port to one or more other ports. The cross-connect (10) is characterized in that the switching means (20) comprises a single switching matrix which is arranged to be capable of switching Optical Data Units (ODU). Alternatively or in addition the switching matrix is arranged to be capable of transparently switching complete Synchronous Digital Hierarchy (SDH) synchronous transport modules STM-N and/or complete SONET synchronous transport signal STS-N derived from optical carriers OC-N and/or SDH virtual containers VC-3, VC-4, and/or concatenated virtual containers VC-4-nc where n=4, 16, 64 or 256 as defined in ITU-T Recommendation G.707 and/or SONET synchronous transport system STS-1s, STS-nc where n=3, 12, 48, 192 or 768 as defined in Telcordia GR253. |
