The IETF PWE3 SAToP/CESoPSN/TDMoIP/HDLC RFC-compliant DS34S108 allows up to eight T1/E1 links or frame-based serial HDLC links to be transported transparently through a switched IP or MPLS packet network. Jitter and wander of recovered clocks conform to G.823/G.824, G.8261, and TDM specifications. This eliminates the need for remote timing sources in cabinets and pedestals.
The Ethernet side of the DS34S108 provides high QoS capabilities to its MII/RMII/SSMII port, while the WAN side supports interfacing to framers and LIUs. The high level of integration that the DS34S108 brings minimizes cost, board space, and time to market.
