OVERVIEW
The CP1158 is one of the OPTRANS series chips designed by Chiphomer Technology Limited. It is a highly integrated EOS device that provides for mapping of 10/100/1000 Mbit/s Ethernet into SDH STM-1 Transport payloads. The device supports connection for up to eight 10/100 Mbit/s Ethernet ports, using SMII or SS-SMII interface, or one 1000 Mbit/s Ethernet port, using GMII interface. Ethernet frames are encapsulated using either GFP or HDLC-like protocol. The encapsulated Ethernet frames are then mapped into virtually concatenated VC-12, VC-3 or VC-4 payloads. Link Capacity Adjustment Scheme (LCAS) for VC-12/VC-3/VC-4 virtual concatenation is provided to enable hitless addition and removal of bandwidth under the control of a network management system. The VC-12, VC-3 and VC-4 POH generation and termination are performed. A byte-wide 19.44MHz Tele Bus interface is provided for the SDH interface.
