| 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.

| Maximum uplink bandwidth |
2.5Gbit/s, supports slot bandwidth adaption. |
| Maximum bound bandwidth |
16xVC-4 or 48xVC-3 |
| 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.
