WTM2000
- Introduction of product
- As the small and medium type optical integration device (I-MUX Plus), this is comprised of branch office side device (COT) and subscriber side device (RT), and subscriber side device accommodates dedicated circuit with 4/8/16DS1(E), 1DS3, 3DS3, 63DS1(E) grade and transmits these optically by multiplexing them, and branch office side device performs demultiplexing of them and circuit distribution function and also conducts the connecting function to network with STM-1 signal and transmission fuction. In addition, this is the device with which DS1(E), DS3 signals can directly be connected to branch office for operation.
- Characteristice of product
- STM-0/STM-1 interface conformed to ITU-T SDH standard
- Various subscriber service interface (DS1, DS1E, DS3, M13) with single platform
- Providing PtMP (Point to Multi-Point) method
- Supporting RT subscriber interface of 16~24 units for each single COT capacity
- Non-Blocking circuit distribution function with VC11/VC12/VC3 unit by utilizing the switching technology of SDH basis
- Provision for AU-3 & AU-4 multiplexing function is possible by connecting STM-1 signal to Network
- Fault Location tracing is simple as LoopBack is possible with the unit of VC11/VC12/VC3 at TSI unit
- Mixed accommodation of STM-0(OC1), STM-1 signal is possible.
- Duplicated structre of main unit and automatic protection transfer function
- Operation and configuration state of system through GUI, transfer state, and monitoring & control function
- Self diagnosis through various LoopBack test functions is simple.
- Visible/audible alarm and state information indication function by LED
