  • Description
    The DS26528 is a single-chip 8-port framer and line interface unit (LIU) combination for T1, E1, and J1 applications. Each channel is independently configurable, supporting both long-haul and short-haul lines.

    Key Features   Applications/Uses
    • Eight Complete T1, E1, or J1 Long-Haul/Short-Haul Transceivers (LIU plus Framer)
    • Independent T1, E1, or J1 Selections for Each Transceiver
    • Internal Software-Selectable Transmit- and Receive-Side Termination for 100Ω T1 Twisted Pair, 110Ω J1 Twisted Pair, 120Ω E1 Twisted Pair, and 75Ω E1 Coaxial Applications
    • Crystal-Less Jitter Attenuator can be Selected for Transmit or Receive Path; Jitter Attenuator Meets ETS CTR 12/13, ITU-T G.736, G.742, G.823, and AT&T Pub 62411
    • External Master Clock can be Multiple of 2.048MHz or 1.544MHz for T1/J1 or E1 Operation; This Clock is Internally Adapted for T1 or E1 Usage in the Host Mode
    • 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
    • T1-to-E1 Conversion

     
  • Channel Banks
  • Channel Service Units (CSUs)
  • Data Service Units (DSUs)
  • Muxes
