DescriptionG7860A supports both MPLS-TP and Carrier Ethernet (EPL, EVPL, EPLAN, 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. Encapsulation technologies include TDMoE, TDMoIP, and TDMoMPLS. Circuit Emulation includes CESoPSN (NxDS0/64K) with CAS, SAToP (Unframed E1/T1), T3, and CEP (SDH/SONET paths). Pseudowires make grooming and multiplexing DS0, E1/T1, T3, and SDH/SONET paths easier, and service integrity can also be monitored and protected via packet network protection schemes. One G7860A with up to 81G packet switching capacity supports six GbE/10GbE SFP+ and four 1GbE SFP built-in interfaces along with 16 E1/T1 built-in ports. With two hot-swappable plug-in slots, the system capacity can be scaled up with additional E1/T1 and T3 ports, STM-n/OC-n, or GbE electrical/optical 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 and ERPS, with protection switching time <50ms. Ethernet and MPLS section and end-to-end OAM are also provided for monitoring service integrity and performance. The compact G7860A is only 1U height, but its powerful functions enable customers to provision a service-grooming hub, ring, or mesh 10G packet network with ultimate ease.
