Product Description

HUAWEI TNH2EGT103 03053657 EGT1 Ethernet transmission board

Product Description:
HUAWEI EGT1 is an Ethernet transparent transmission board.

Function and Feature	Description
Basic functions	Transparently transmits one channel of GE signals.
Interface specifications	Provides one 1000BASE-SX/1000BASE-LX/1000BASE-VX/1000BASE-ZX Ethernet optical port that supports auto-negotiation and complies with IEEE 802.3z; uses hot-swappable SFP optical modules. The GE optical port supports single-fiber bidirectional optical modules.
Format of service frames	Ethernet II, IEEE 802.3, or IEEE 802.1q/p Supports a frame length ranging from 64 bytes to 9,600 bytes.
Maximum uplink bandwidth	4xVC-4
VCTRUNK	1
Encapsulation format	Supports HDLC, LAPS, and GFP-F.
Service level and Concatenation granularity	VC-3, VC-4, VC12-Xv (X ≤ 63), VC3-Xv (X ≤ 12), and VC4-Xv (X ≤ 4)
Ethernet service	Supports EPL.
MTU	Supports the setting of the packet length (ranging from 1,518 bytes to 9,600 bytes). After the new resetting takes effect, the permissible maximum length of the packets accessed at the IP interface depends on the MTU settings.
MPLS	Not supported
VLAN	Supports transparent VLAN transmission.
LPT	Supports point-to-point Link State Pass Through (LPT).
Multicast	Not supported
ETH-OAM	Supports the continuity check (CC) for the multicast services, loopback (LB) test for the unicast services, network loopback detection (LD), link trace (LT) test, auto-negotiation, fault diagnosis, and link performance check.
CAR	Not supported
Flow control	Supports the GE port-based IEEE 802.3x flow control.
LCAS	Dynamically increases or decreases the bandwidth and realizes the protection function, compliant with the ITU-T G.7042 Recommendations.
Ethernet test frame	Supports the reception and transmission of Ethernet test frames.
Ethernet performance monitoring (RMON)	Supports Ethernet performance monitoring at the port level.
Alarm and performance event	Provides rich alarms and performance events for easy management and maintenance of the equipment.

Working Principle

Composition: The EGT1 board consists of an interface module, a service processing module, an encapsulation/mapping module, a communication and control module, and a power supply unit.
Signal Flow: In the receiving direction, the Ethernet frame is received by the interface module, and after processing by the service processing module, it is sent to the mapping module for VC - 12 or VC - 3 mapping and then sent to the cross - unit. In the sending direction, the VC - 12 or VC - 3 signal sent by the cross - unit is demapped and then sent to the encapsulation module for de - encapsulation. After that, the service processing module determines the route, performs flow classification, and completes functions such as frame delimiter, pre - code addition, CRC check code calculation, and Ethernet performance statistics. Finally, it is sent out through the Ethernet interface after serial - parallel conversion and encoding by the interface processing module. The control and communication module realizes the communication, control, and service configuration functions of the board, and the power supply unit provides the required DC power for all modules of the board.
