  • Receive-Signal Level Indication from -2.5dB to -36dB in T1 Mode and -2.5dB to -44dB in E1 Mode in Approximate 2.5dB Increments
  • Transmit Open- and Short-Circuit Detection
  • LIU LOS in Accordance with G.775, ETS 300 233, and T1.231
  • Transmit Synchronizer
  • Flexible Signaling Extraction and Insertion Using Either the System Interface or Microprocessor Port
  • Alarm Detection and Insertion
  • T1 Framing Formats of D4, SLC-96, and ESF
  • J1 Support
  • E1 G.704 and CRC-4 Multiframe
  • Controlled by 8-Bit Parallel Port Interface or Serial Peripheral Interface (SPI)
