com OVERVIEW The CP1154 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 four 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.
