TNF1EGS4 is a 4-port GE switching and processing board applied to Huawei OSN 1800 I Enhanced, OSN 1800 II Enhanced, OSN 1800V. The EGS4 is used to transmit/receive Ethernet services, manage bandwidths, and realize Layer 2 switching of Ethernet services.
|There are ports on the front panel of the board.|
|Specifications (EGS4 boards)|
Receives/Transmits and processes 4xFE or 4xGE services.
If created as the EGS4 or EGS4D board on the NMS, the board supports EoS application.
GE electrical port: auto-negotiation, 1000M full-duplex, 100M full-duplex, and 10M full-duplex
GE optical port: auto-negotiation and 1000M full-duplex
FE optical port: 100M full-duplex
|Service specifications||Frame length range|
Supports the setting of the frame length to a value ranging from 1518 bytes to 9600 bytes.
Supports a jumbo frame with a maximum length of 9600 bytes.
16 x VC-4, or 48 x VC-3, or 252 x VC-12
|Concatenation granularities||VC-12, VC-3, VC-4, VC-12-Xv (X ≤ 63), VC-3-Xv (X ≤ 24), and VC-4-Xv (X ≤ 8).|
|Maximum uplink bandwidth|
Configuration principles are as follows:
Supports a maximum of 16 VC-4s.
When a lower-order channel is bound, VC-4 channels numbered 1 to 4 support the binding of VC-3 and VC-12 channels. VC-4 channels numbered 5 to 16 support the binding of VC-3 channels only.
|Specifications (EGS4D boards)|
1.On the EGS4D board, two port channels for connecting to the packet plane and SDH plane are added. One channel connects to an EoD port (internal port of IN1/OUT1) and virtual port 5, and the other channel connects to an EoD port (internal port of IN2/OUT2) and virtual port 6.
2.In the EoD application scenario, the board can transmit a maximum of 2 x GE optical signals. The supported transmission scenarios are as follows:
SDH service from the cross-connect board <-> EoD port <-> virtual port <-> packet plane (packet board)
GE optical signal at the IN3/OUT3 and IN4/OUT4 ports of the EGS4D board <-> EoD port <-> virtual port <-> packet plane (packet board)
Hybrid transmission of the two services
3.The EGS4D board supports both EoD and EoS applications.
4.In the EoD application scenario, virtual ports 5 and 6 provide the packet feature, and the packet attribute must be configured for virtual ports 5 and 6. The EGS4D board does not support packet data processing. Instead, packet data is processed by packet boards and cross-connect boards.
The channels support the EoD function only when the EGS4 board is created as the EGS4D board on the NMS and the IN1/OUT1 and IN2/OUT2 ports are set to the EoD mode.
In the EoD application scenario, the working mode of the EoD port is 1000M full-duplex.
In the EoD application scenario, the maximum frame length of the EoD port is 9600.
