PTN-MPLS-Carrier Ethernet

PTN - 10GE MPLS/CE Access Node - G7860A - mPTN

G7860A is an Access Node to support 10GbE Packet Transport Networks using MPLS-TP or Carrier Ethernet architecture. G7860A, in addition to generic Ethernet traffic, also supports TDM signals including DS0, E1/T1, and STM-n/OC-n via Circuit Emulation and Encapsulation technologies. Clock Synchronization is achieved via SyncE and IEEE 1588v2.

G7860A supports both MPLS-TP and Carrier Ethernet (EPL, EVPL, ELAN, EVC defined in MEF) for packet transportation. In addition to native Ethernet transport, G7860A can be used as the gateway for PDH and SDH/SONET networks to enter PSNs using Circuit Emulation and Encapsulation technologies. TDM encapsulation technologies of G7860A support TDMoE, TDMoIP, and TDMoMPLS, while Circuit Emulation technologies supported by G7860A are CESoPSN (Nx64K), SAToP (Unframed E1/T1), and CEP (SDH/SONET Circuit Emulation over Packet).

One G7860A with up to 85G packet switching capacity supports six 10GbE SFP+ and four 1GbE SFP built-in interfaces along with 32 E1/T1 built-in ports. With the two hot-swappable plug-in slots, the system capacity can be scaled up with additional E1/T1 ports, STM-n/OC-n, or GbE interfaces.

G7860A provides high availability and reliability required by Carrier, Power Utility, Military, Government and Transportation applications by supporting MPLS-TP LSP 1:1/1+1 protection with protection switching time lower than 50ms, while section and end-to-end OAM are supported for monitoring. The compact G7860A is only 1U height, but it enables customers to construct a hub, ring, or mesh Packet network via its ultimate powerful functions.
