Throughout the data sheet, J1 is represented wherever T1 exists.

Receive sensitivity adjusts automatically to the ining signal and can be programmed for 0dB to 12dB or 0dB to 43dB for E1 applications and 0dB to 30dB or 0dB to 36dB for T1 applications.

Key Features

  • Complete E1, T1, or J1 line interface unit (LIU) Supports both long- and short-haul trunks Internal software-selectable receive-side termination for 75Ω/100Ω/120W 5V power supply 32-bit or 128-bit crystal-less jitter attenuator requires only a 2.048MHz master clock for both E1 and T1 with option to use 1.544MHz for T1 Generates the appropriate line build outs, with and without return loss, for E1 and DSX-1 and CSU line build outs for T1 AMI, HDB3, and B8ZS, encoding.
