OVERVIEW
The CP1121A 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
integrated one SDH overhead processor for dual STM-4 or dual STM-1,
one extend interface for dual STM-4s or dual STM-1s, a tributary unit
payload processor for 8 STM-1, E1 mapper for asynchronous mapping
and demapping of 21 port E1, a 18 X 18 high and low order cross
connecter.
