Giới thiệu
The Repeater is E1 long-haul, OSI Layer One repeaters. The compact design, low cost, and easy operation and an excellent choice for E1 link extension. provides a simple 1 pair (Tx/Rx) in, 1 pair (Tx/Rx) out repeater interface, Setup is extremely simple. Just select the proper termination impedance from the three position slide switch (120 Ohm for E1) and The E1 signal is completely recovered with new pulse shape and low jitters.
