PT7860A is a MPLS-TP & CE2.0  Packet Transport Network multiplexer with synchronization and TDM SDH/PDH Circuit Emulation Services 


PT7860A provides PTN MPLS-TP and CE2.0 communications (EPL, EVPL, EPLAN, EVC) with PDH and SDH Circuit Emulation Services according to SAT over IP, CES over IP, TDM over IP et TDM over MPLS standards.

PT7860A has a switching capacity of 85 Gbps. It delivers 6x 10GE interfaces and 4x GE SFP ports as well as 8 or 16 E1 interfaces. It has 2x modular slots to host Ethernet, E1 or SDH cards.

PT7860A enables PDH/SDH network migration to latest PTN MPLS-TP and Carrier Ethernet technologies and it helps cost effective and flexible bandwidth upgrade to 10 Gigabit.

PT7860A ensures high availability required by operators and service providers thanks to its redundant architecture and its circuit protection features with lower than 50 ms recovery delay over MPLS-TP and CE2.0 connectins.

PT7860A is desinged in a compact 1U/19'' chassis with an extended -20 to +65 °C operating temperature range.
