The IETF PWE3 SAToP/CESoPSN/HDLC-compliant DS34S132 provides the interworking functions that are required for translating TDM data streams into and out of TDM-over-Packet (TDMoP) data streams for L2TPv3/IP, UDP/IP, MPLS (MFA-8), and Metro Ethernet (MEF-8) networks while meeting the jitter and wander timing performance that is required by the public network (ITU G.823, G.824, and G.8261). Up to 32 TDM ports can be translated into as many as 256 individually configurable pseudowires (PWs) for transmission over a 100/1000Mbps Ethernet port. Each TDM port's bit rate can vary from 64Kbps to 2.048Mbps to support T1/E1 or slower TDM rates. PW interworking for TDM-based serial HDLC data is also supported. A built-in time-slot assignment (TSA) circuit provides the ability to combine any group of time slots (TS) from a single TDM port into a single PW. The high level of integration provides the perfect solution for high-density applications to minimize cost, board space, and time to market.
