Description

TN11LEM24 overview

 

TN11LEM24 22 x GE + 2 x 10GE and 2 x OTU2 Ethernet Switch board applied to OptiX OSN 8800/6800/3800.

The OptiX OSN 8800 Intelligent Optical Transport Platform (OptiX OSN 8800 for short) is a new generation of intelligent MS-OTN product. The OptiX OSN 8800 can interconnect with any product from the OptiX OSN product series, such as the OptiX OSN 1800, to form an end-to-end OTN network. The OptiX OSN 8800 T32/T16 supports unified switching and control based on ODUk, VC, and packets, achieving unified switching and transmission for multiple services on a single multi-service optical transport network (MS-OTN). The OptiX OSN 6800 Intelligent Optical Transport Platform (OptiX OSN 6800 for short) is referred to as Huawei next generation intelligent optical transport platform. The OptiX OSN 6800 is for area backbones, local networks, metropolitan convergence layers and metropolitan core layers. It may also work with other WDM, SDH/SONET equipment to offer a complete Metro WDM solution.

OTN Functions and features of the LEM24 board
Basic function
  • Converts 22 channels of GE/FE services and two channels of 10GE WAN/10GE LAN services received directly on the client side into two channels of standard WDM wavelength OTU2 signals and performs the reverse process.If being used by the OptiX OSN 6800, this board can also converge and convert a maximum of two channels of 10GE services cross-connected from the backplane into OTU2 signals.
  • Converges multiple flat-rate GE or 10GE services into one channel of 10GE service.
Client-side service type FE: Ethernet service at a rate of 125 Mbit/s. Supports FE optical signals and FE electrical signals. GE: Ethernet service at a rate of 1.25 Gbit/s. Supports GE optical signals and GE electrical signals. 10GE LAN: Ethernet service at a rate of 10.31 Gbit/s 10GE WAN: Ethernet service at a rate of 9.95 Gbit/s
NOTE:
  • The LEM24 board supports both FE/GE electrical signals and FE/GE optical signal.
  • When the LEM24 board transmits GE or FE electrical signals, to facilitate fiber routing, you are advised to install electrical modules at the RX21/TX21 and RX22/TX22 ports.
Cross-connect capabilities OptiX OSN 8800: N/A. OptiX OSN 6800: Supports the cross-connection of two channels of 10GE electrical signals between the LEM24 board and the cross-connect board. OptiX OSN 3800: N/A.
OTN function
  • Provides OTU2 interfaces on the WDM side.
  • Supports SM function for OTU2.
  • Supports PM and TCM functions for ODU2.
WDM specification Supports DWDM specifications.
ESC function Supported
LPT
  • Supports port-based LPT.
  • Supports service-based LPT.
NOTE:
The board supports port-based LPT only when EPL services (port <-> VCTRUNK) are provisioned and supports service-based LPT only when EVPL or QinQ services (port <-> VCTRUNK) are provisioned.
FEC encoding Supports ITU-T G.709-compliant forward error correction (FEC) on the WDM side.
Alarms and performance events monitoring
  • Monitors BIP8 bytes (Bursty mode) to help locate line failures.
  • Monitors parameters such as the bias current, temperature, and optical power of the laser.
  • Monitors OTN alarms and performance events.
  • Supports monitoring of performance events and alarms associated with FE, GE, 10GE WAN, and 10GE LAN services.
Regeneration board The WDM-side signals from one TN11LEM24 board can be regenerated by another TN12ND2/TN52ND2/TN53ND2/TN55NO2/TN53NQ2/TN54NQ2/TN11LSXR board.
ALS function Supports the ALS function on the client side.
NOTE:
ALS function is supported only when EPL services (port <-> VCTRUNK) are provisioned.
IEEE 1588v2 Supported in the WDM side.
Physical clock Supported in the Client side and WDM side.Supports synchronous Ethernet processing instead of synchronous Ethernet transparent transmission on the client side.
NOTE:
The board does not support the physical clock when it is provisioned with 10G WAN services.
PRBS test function Supports the PRBS function on the WDM side
Test frame Supported
Latency measurement Not supported

Electrical-layer ASON Not supported
Protection scheme
  • Supports client 1+1 protection.
  • Supports intra-board 1+1 protection (when working with the OLP/DCP/QCP board).
  • Supports OWSP protection.
NOTE:
Client 1+1 protection is supported only when EPL services (port <-> VCTRUNK) are provisioned.
