IPM-E1, IPM-4E1

Supports Web Management
Supports IETF RFC4553 Structure-Agnostic TDM over Packet (SAToP), Metro Ethernet Forum MEF8
Use Raw Encapsulation method for PDH payload over Ethernet packet
Supports Circuit Emulation Service over Ethernet networks
Comply with IETF draft standard for CESoPSN and SAToP; Metro Ethernet Forum MEF8 IA

Configurable jitter buffer depth to compensate PDV (Packet Delay Variation) with the flexible setting of 11ms, 23ms, 40ms, 75 ms
Lost packets processing / compensation via PW (Pseudo Wire) control field Sequence Number
Provide Subscriber side Data traffic bandwidth control to guarantee enough TDM payload bandwidth
PDH LOS detection triggered PW L field or payload AIS generation at Egress direction (TDM->PSN)
Configurable IEEE 802.3 DA/SA assignment
LED alarm display for E1 Power failure status
E1 NRZ Serial Interface with LOS/AIS detection
