IPM-4SE TDM over IP

IPM-4SE is designed as a multiservice access platform for PDH over Ethernet applications. E1 frames can be mapped/de-mapped 9 into/from Ethernet packets. An adaptive clock recovery method for Ingress PDH (PSN ->TDM) clock generation is implemented to support 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 to interconnect existing phone systems over Ethernet that are used to carry data, voice and video. With high precision clock recovery technology, IPM-4SE is capable of supporting 2G/3G backhaul and provides smooth services. IPM-4SE can transparently transport proprietary signaling that is required to support PBX features, including call conference, call forwarding and SS7.

Features:

⊙ Supports IEFT RFC4533 Structure-Agnostic TDM over Packet (SAToP), Metro Ethernet Forum MEF8.
⊙ 4 x E1 NRZ Serial Interface with LOS/AIS detection
⊙ Use Raw Encapsulation method for PDH payload over IP packet.
⊙ Supports Circuit Emulation Service over IP.
⊙ Comply with IEFT draft standard for CESoPSN and SAToP; Metro Ethernet Forum MEF8 IA.
⊙ Supports Point-to-Point operation.
⊙ Supports 4 independent Adaptive Clock recovery block for Ingress PDH (PSN -> TDM) clock generation. Recovered clock jitter is compliant with ITU-T G.824 (E1 Jitter Control).
⊙ Independent configurable jitter buffer depth to compensate up to 250ms of Packet Delay Variation.
⊙ Supports framed/unframed traffic (ITU-T G.704)
⊙ Lost packets processing/compensation via PW (Pseudo Wire) control field Sequence Number.
⊙ Provides Subscriber side data traffic bandwidth control to guarantee enough TDM payload bandwidth.
⊙ PDH LOS detection triggered PWL field or payload AIS generation at Egress direction (TDM -> PSN).
⊙ Configurable IEEE 802.3 DA/SA assignment.
⊙ Configuration can be made through RS-232 console port.
