That the thread frame is suitable to transmit the sign indicating number Shuai for the numeral terminal equipment or the joining in marriage thread of the digital signal of program controlled switch below the 2-155MB / S and resets
is joined in marriage that to MPX3999A's mould numeral, and possesses functions such as circuit dispatch, resets and test etc. Safeguard the use convenience. The needs of circuit accent thread and vocational work change can be realized
nimblely.

• The machine frame adopts unlimited type the structure, construction and maintenance are made things convenient for.
• The unit type makes up, and disposes nimble(ly), and it is convenient to install.
• Adopting surperficial gold-plating 2um's coaxial connector, the contact
  resistance is low, and links reliably, and joins in marriage thread, accent thread and monitors very convenience, 90 °s' module bring over backwards
  downward, and is easy to operate safeguards.。
• The machine has the sufficient wiring inside the frame, and walks the thread space.
• The SIEMENS same product can be replaced.

• Characteristic impedance：75Ω
• Work speed：2Mb/s,34Mb/s,140Mb/s,155Mb/s
• Coaxial connector contact resistance：Outer Conductor≤2.5mΩ  Interior conductor≤10mΩ
• Insulation resistance：≥1000MΩ/500V(DC)
• Be able to endure voltage ：≥1000V(50HzAC)/1Min,
  No Puncture and have not the arc flying
• Intervene the loss ：≤0.3dB(50KHz-233MHz)
• Echo loss ：≥18dB(50KHz-233MHz)
• Pulling force ：> 50N
