TMB1EMS10 is a 10-channel Ethernet service EoS switching and processing board applied to Huawei OSN 1800 I Enhanced, OSN 1800 II Enhanced, OSN 1800V. The EMS10 board is mainly used in the telecommunications application fields such as Ethernet service access, bandwidth management, and Ethernet service Layer 2 switching.

Tech Specs
Front Panel
There are ports on the front panel of the board.



Basic function Transmits/Receives ten Ethernet services, encapsulates and maps the Ethernet services into SDH signals, and forwards the SDH signals to the SDH plane for transmission.



Transmits/Receives a maximum of one 10GE service.

Transmits/Receives a maximum of ten GE/FE services.

For GE electrical services: A maximum of six unshielded network cables can be used. A maximum of four shielded network cables can be used.

Working modes GE electrical port: auto-negotiation, 1000M full-duplex, 100M full-duplex, and 10M full-duplex

10GE optical ports: 10GE full-duplex LAN

GE optical port: auto-negotiation and 1000M full-duplex

FE optical port: 100M full-duplex

Number of services 2000 unidirectional services
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.

Bound bandwidth 16 x VC-4, 48 x VC-3, or 504 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 2.5 Gbit/s.
VCTRUNK specifications 64


Configuration principles are as follows:

Supports a maximum of 16 VC-4 channels.

When a lower-order channel is bound, VC-4 channels numbered 1 to 8 support the binding of VC-3 and VC-12 channels. VC-4 channels numbered 9 to 16 support the binding of VC-3 channels only.
