Function and Feature

Description

Basic function

TDX converts signals as follows:

1. TN11TDX: 2x10GE LAN/10GE WAN/STM-64/OC-192<->8xODU1 virtual concatenation electrical signals
2. TN12TDX:

2x10GE LAN/10GE WAN/STM-64/OC-192<->2xODU2

2x10GE LAN<->2xODU2e

1.  
2. TN52TDX:

2x10GE LAN/10GE WAN/STM-64/OC-192/OTU2<->2xODU2

2x10GE LAN/OTU2e<->2xODU2e

1.  
2. TN53TDX:

2x10GE LAN/10GE WAN/STM-64/OC-192/OTU2/FC800<->2xODU2

2x10GE LAN/OTU2e/FC1200<->2xODU2e

2xFC800<->2xODUflex

Client-side service type

STM-64/OC-192: SDH/SONET service at a rate of 9.95 Gbit/s

10GE LAN: Ethernet service at a rate of 10.31 Gbit/s

10GE WAN: Ethernet service at a rate of 9.95 Gbit/s

OTU2: OTN service at a rate of 10.71 Gbit/s

OTU2e: OTN service at a rate of 11.1 Gbit/s

FC800: SAN service at a rate of 8.5 Gbit/s

FC1200: SAN service at a rate of 10.51 Gbit/s

NOTE:

The processing of the 10GE WAN service and the STM-64 service is the same. Therefore, For TN11TDX/TN12TDX/TN52TDX board, when the 10GE WAN service is transmitted, you can configure it as the STM-64 service on the U2000.

Cross-connect capabilities

OptiX OSN 8800:

1. TN52TDX: Supports the cross-connection of two channels of ODU2/ODU2e signals between the TDX board and the cross-connect board using the backplane.
2. TN53TDX: Supports the cross-connection of two channels of ODU2/ODU2e/ODUflex signals between the TDX board and the cross-connect board using the backplane.

OptiX OSN 6800:

1. TN11TDX: Supports the cross-connection of eight channels of ODU1 signals between the TDX board and the cross-connect board or the board in the paired slot using the backplane.
2. TN12TDX/TN52TDX/TN53TDX: Supports the cross-connection of two channels of ODU2/ODU2e signals between the TDX board and the cross-connect board using the backplane.

OptiX OSN 3800:

1. TN11TDX: Supports the grooming of eight channels of ODU1 signals from one board of the mesh group (consisting of four boards) to the other three boards belonging to the mesh group.

OTN function

1. Supports the OTN frame format and overhead processing by referring to the ITU-T G.709. The mapping process is compliant with ITU-T G.709 and G.Sup43.
2. Supports PM functions for ODU2.

ESC function

Supported by the TN52TDX/TN53TDX when the client-side service type is OTU2 or OTU2e.

PRBS test function

Supports the PRBS function on the client side.

NOTE:

The PRBS function on the client side is supported only when the client-side service type is STM-64/OC-192, OTU2 or OTU2e.

LPT function

The board supports the LPT function only when the client-side service type is 10GE LAN.

FEC coding

Supports ITU-T G.709-compliant forward error correction (FEC) on the client side, only when the service type is OTU2/OTU2e.

Alarms and performance events monitoring

1. Monitors BIP8 bytes (Poisson mode or Bursty mode) to help locate line failures.
2. Monitors B1 bytes to help locate faults.
3. Monitors OTN alarms and performance events.
4. Monitors parameters such as the bias current, temperature, and optical power of the laser.
5. Supports the remote monitoring (RMON) of Ethernet services (10GE LAN).

NOTE:

TN11TDX only supports Poisson mode.

TN12TDX/TN52TDX/TN53TDX only supports Bursty mode.

ALS function

Supports the ALS function on the client side when client services are non-OTN services.

Test frame

Supports the test frame function when the client-side service type is 10GE LAN and the Port mapping is MAC Transparent Mapping (10.7 G).

Latency measurement

The TN53TDX board supports latency measurement. The bidirectional latency at the ODUk layer between two tributary boards supporting the latency measurement function can be measured, and the latency data is displayed on the U2000.

NOTE:

This function is not supported when the client-side service type is OTU2/OTU2e.

IEEE 1588v2

The TN53TDX board supports the TC, TC+OC, BC, and OC modes when the client-side service type is 10GE LAN and the Port mapping is MAC Transparent Mapping (10.7 G).

Physical clock

TN53TDX:

1. When the board receives 10GE LAN services and the port mapping is Bit Transparent Mapping (11.1 G) on its client side, the board can support synchronous Ethernet transparent transmission instead of synchronous Ethernet processing.
2. When the board receives 10GE LAN services and the port mapping is MAC Transparent Mapping (10.7 G). on its client side, the board can support synchronous Ethernet processing instead of synchronous Ethernet transparent transmission.

TN52TDX:

When the board receives 10GE LAN services and the port mapping is Bit Transparent Mapping (11.1 G) on its client side, the board can support synchronous Ethernet transparent transmission instead of synchronous Ethernet processing.

Electrical-layer ASON

Supported by the TN52TDX/TN53TDX.

Protection scheme

1. Supports ODUk SNCP.
2. Supports client 1+1 protection.
3. Supports tributary SNCP protection (TN12TDX/TN52TDX/TN53TDX).

NOTE:

When the cross-connect granularity is ODUflex, the board does not support tributary SNCP protection.

NOTE:

When the board receives OTN services, SDH/SONET services, and 10GE WAN services the board supports tributary SNCP protection.

Ethernet service mapping mode

1. TN11TDX: doesn't support this parameter
2. TN12TDX/TN52TDX/TN53TDX: Bit Transparent Mapping(11.1G), MAC transparent mapping (10.7G)

Port MTU

The value ranges from 1518 to 9600, in bytes. That is, the maximum size of the supported Jumbo frame is 9600 bytes.

NOTE:

when Port Mapping is set to Bit Transparent Mapping(11.1G), Maximum Packet Length is unavailable on the U2000.
