IPM-4SE is designed as a multiservice access platform for PDH over Ethernet applications. E1 frames can be mapped/de-mapped 9into/from Ethernet packets. An adaptive clock recovery method for Ingress PDH (PSN ->TDM) clock generation is implemented tosupport E1(ITU-T G.823) Jitter performance.
IPM-4SE provides cost-effective applications of traditional circuit switched system over Ethernet. With IPM-4SE, it is easy tointerconnect existing phone systems over Ethernet that are used to carry data, voice and video. With high precision clock recoverytechnology, IPM-4SE is capable of supporting 2G/3G backhaul and provides smooth services. IPM-4SE can transparently transportproprietary signaling that is required to support PBX features, including call conference, call forwarding and SS7.
