Chip CP1122
The CP1122 is one of the OPTRANS series chips designed by Chiphomer Technology Limited. It is extended to provide a flexible, low cost System-on-chip (SOC) solution for fast growing metropolitan transmission market, especially in Multi-service Transport Platform (MSTP) and Customer Premises Equipment (CPE) applications. It integrates one SDH overhead processor for dual STM-1, one extension interface for dual STM-1, a tributary unit payload processor for 2 STM-1, E1 mapper for asynchronous mapping and demapping of 21 E1 ports, a 6 X 6 high and low order cross connector.
