4E1 TDM to Ethernet Converter (CESOPSN / SAToP) is designed as a multiservice access platform for PDH and V.35 over Ethernet applications.


Structured / unstructured E1 and V.35 data can be mapped/de-mapped into/ from Ethernet packets.


An adaptive clock recovery method for Ingress PDH (PSN -> TDM) clock generation is implemented to support E1 (ITU-TG.824) Jitter performance.



COST-EFFECTIVE LAN DEPLOYMENT (PDH AND V.35 OVER ETHERNET) :
TDM Over IPprovides cost-effective applications of traditional circuitswitched system over Ethernet. With TDM Over IP, it is easy to interconnect with existing phone systems and V.35 over Ethernet that are used to carry data, voice and video.


TRANSPARENT TRANSMISSION :
TDM Over IPcan transparently transport proprietary signaling that are required to support PBX features, including call conference, call forwarding and SS7. Customer can easily apply and enjoy better integration of TDM, V.35 and Ethernet devices with lower network expense.


BYPASS INTERNATIONAL TOLL :
With a pair of TDM Over IPand guaranteed internet bandwidth, it is sure to save cost dramatically, and to ensure the QoS of voice based on interconnections of TDM telecommunications equipment.
