PTN - 10GE MPLS Access Node - G7860-mPTN

Model: G7860-

The Loop-G7860 mPTN (MPLS/CE Packet Transport Network) is a new and cost-effective solution for transmitting various data service types, including traditional TDM circuit-based traffic, over a packet-based transportation network.

By adopting MPLS-TP (Multi-Protocol Label Switching Transport Profile) and Carrier Ethernet technologies, the G7860 can transport Ethernet (EPL, EVPL, ELAN, EVC defined in MEF), E1/T1 TDMoE, and SDH/SONET CEP traffic.

The unit is also equipped with OAM tools to perform diagnosis on the LSPs (Label Switched Paths), pseudowires as well as Ethernet CFM. The Loop-G7860 series is a perfect packet transport platform for IP-Mobile and lease-line applications containing hub, ring and mesh topologies.
