The main functions and features supported by the TSP board are wavelength conversion, cross-connections, clock, and multiplexing of STM-1/E1/T1 signals.
| Function and Feature | Description | |
| Basic Function | Accesses 21 channels of E1/T1 electrical signals and two channels of STM-1 electrical/optical signals, and converts the input signals into two channels of STM-4/STM-16 optical signals or two channels of STM-1 electrical/optical signals. |
|
| The optical ports on the WDM side provide the dual fed and selective receiving function (implemented through the electrical-layer SNCP). |
||
| Working mode | Supports the SDH+WDM mode and SDH simplified mode. | |
| NOTE: | ||
| The working mode can be set to the SDH simplified mode only when the TNF1TSPB board works with the 1800 V system control board, 1800 II Enhanced system control board or 1800 I&II Compact TNF3SCC board. In this case, the board works in the SDH simplified mode by default. |
||
| NOTE: | ||
| When the TSP boards are interconnected, it is advised to configure the same working mode for them. |
||
| Service type | STM-1: SDH services, the rate is 155.52 Mbit/s. | |
| STM-4: SDH services, the rate is 622.08 Mbit/s. | ||
| STM-16: SDH services, the rate is 2.488 Gbit/s. | ||
| NOTE: | ||
| The board does not support the STM-16 service when working with the TNF1SCC board. |
||
| E1(75/120 ohms): PDH services, the rate is 2.048 Mbit/s. | ||
| T1 (100 ohms): PDH services, the rate is 1.544 Mbit/s. | ||
| NOTE: | ||
| If the STM-1 electrical module is installed in a port, no electrical or optical modules can be installed in its adjacent ports. |
||
| FEC function | Not supported | |
| Alarms and performance events monitoring | Provides abundant alarms and performance events to facilitate management and maintenance of the equipment. |
|
| Monitors performance parameters and alarm signals, including the monitoring of laser bias current, laser working temperature and optical power on the WDM side. |
||
| Protection schemes | Supports SNCP protection | |
| Overhead processing | Supports processing of section overheads of the STM-1/STM-4/ STM-16 signals. |
|
| Supports the transparent transmission and termination of path overheads. |
||
| Supports the setting and querying of the J0/J1/J2/C2/V5 byte. | ||
| Supports processing of the AU/TU pointer. | ||
| Supports one to four channels for DCC communication. | ||
| Tributary function | Receives/Transmits 21 channels of 75-ohm/120-ohm E1 or 100-ohm T1 signals. |
|
| Asynchronously maps E1/T1 signals into VC-12 containers. | ||
| Processes overheads of VC-12 paths, and monitors alarms on the service paths. |
||
| Provides inloop and outloop to test the quality of E1/T1 services or to locate a faulty point, facilitating the maintenance of the equipment. |
||
| Provides the clock unit with two tributary clock sources contained in the first channel of signals and the twenty-first channel of signals output by the tributary-side port. |
||
| Clock function | Supports the non-SSM protocol, standard SSM protocol and extended SSM protocol. |
|
| Provides the synchronization clock required by the board. | ||
| Provides the clock unit with seven synchronous timing sources contained in the two channels of signals output by the two client-side ports, two channels of signals output by the two WDM-side ports, one channel of signals output by the external clock port, and the first channel of signals and the twenty-first channel of signals output by the tributary-side port. |
||
| Supports the three working modes: trace, hold-over, and free-run. | ||
| Supports the control of the clock source priority levels. | ||
| Supports the control of the clock source switching function. | ||
| Processes and sets the S1 byte. | ||
| Provides one 2048 KHz or 2048 kbit/s external clock ports, of which the impedance is 120 ohms. The 2M export operation exports system source clocks only. |
||
| Supports tributary retiming. | ||
| Loopback | Supports inloop and outloop on a WDM-side VC-4 path. | |
| Supports inloop and outloop on a client-side VC-4 path. | ||
| Supports inloop and outloop on each tributary path (1-21 paths). | ||
| Regeneration board | LWX2 | |
| ALS function | Not supported | |
| ESC function | Supported | |
| LPT function | Not supported | |
| PRBS test | Supports the PRBS function on the client side and tributary side. | |
| NOTE: | ||
| The PRBS function on the client side is supported only when the client-side service type is STM-1, and on the tributary side is supported only when the client-side service type is E1/T1. |
||
| Cross-connect function | Supports 11x11 cross-connections of VC-4 signals, or 693x693 full cross-connections of VC-12 signals. |
|
| Supports two cross-connections on the WDM side of the TSP board to the client side of the LQM2 board. |
||
| Supports cross-connections of STM-1/STM-4/STM-16 services between paired slots, cross-connections between transverse slots, and cross-connections between diagonal slots. For details, see Slots for Cross-Connect Boards. |
||
| WDM specifications | Supports ITU-T G.694.1-compliant DWDM specifications and ITU-T G.694.2-compliant CWDM specifications. | |
