Stand alone port

Single modular stand alone port for E1 DSU/CSU

  • Supports user-selectable transmission rates via randomly selected E1 timeslots.
  • Provides an approximate operating range up to 2km (using 22AWG) and integral multiples of 64kbps, up to a maximum 2.048Mbps (unframed). For a line attenuation of up to 43 dB on twisted pair or coax cable.
  • Unused time slots can insert IDLE code (in frame mode).
