28560-DSH-001-B
1.0 Introduction
The CX28560 is a 2047-channel communications controller targeted at synchronous
link layer applications that provides a comprehensive, high density solution for
HDLC internetworking applications.
The CX28560 HDLC controller interfaces to 32 independent serial data streams such
as DS0, T1/E1, T3/E3, STS-1/STM-1. Data is transferred between the system and the
CX28560 across a standard, high performance, 32-bit POS-PHY bus as fragments of
complete packets. In the Transmit direction, the CX28560 provides the system with
buffer state information across an 8-bit/100 MHz standard POS-PHY bus level 3
(FlowConductor™ bus).
