| Basic Functions | Transparent transmission of 2 GE services |
| Interface type | Support 1000BASE-SX/LX/ZX/VX Ethernet optical interface, support self-negotiation function, meet IEEE802.3z standard. Adopting pluggable SFP optical module, the transmission distance can reach up to 550m for multi-mode fiber and 10km for single-mode fiber (40km and 80km optical modules can also be selected according to the actual needs). N2EGT2 also supports 1000Base-T Ethernet electrical interface, which supports 1000M full-duplex operation mode. With the pluggable SFP electrical interface, the transmission distance can reach up to 100m.

| VCTRUNK Specifications |
Quantity: 2 Configuration Features: After each level of VC channel is used by one VCTRUNK binding, other VCTRUNKs can no longer be used. VCTRUNK1 is required to be bound for use when the slot bandwidth is 1.25G bit/s. One VCTRUNK can bind up to 8 VC-4s (or 24 VC-3s); the channels that can be bound by each VCTRUNK can be selected arbitrarily from 1 to 16 VC-4s (or 1 to 48 VC-3s). For N1EGT2 single board, the virtual cascade mode of the 2 VCTRUNKs must be the same, i.e., both VCTRUNKs must be VC-4 level virtual cascade, or both VC-3 level virtual cascade. For N2EGT2 single board, there is no such restriction.
