HUAWEI EGT1 TNH2EGT1 2103053619 1xGE Transparent for OSN500 OSN550

Function and Feature

Description

Basic functions

Transparently transmits one channel of GE signals.

Interface specifications

Format of service frames

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.
