Product Brief
8-port Ethernet Over SDH Mapping Device
CP1158
OPTRANS Series
www.daOtasVheEet4Ru.cVomIEW
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 Telecom Bus interface is provided for the SDH
interface.
