概览
优势和特点
- 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/120Ω
- 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/decoding
- 16.384MHz, 8.192MHz, 4.096MHz, or 2.048MHz clock output synthesized to recovered clock
- Programmable monitor mode for receiver
- Loopbacks and PRBS pattern generation/ detection with output for received errors
- Generates/detects in-band loop codes, 1 to 16 bits including CSU loop codes
- 8-bit parallel or serial interface with optional hardware mode
- Multiplexed and nonmultiplexed parallel bus supports Intel or Motorola
- Detects/generates blue (AIS) alarms
- NRZ/bipolar interface for TX/RX data I/O
- Transmit open-circuit detection
- Receive Carrier Loss (RCL) indication (G.775)
- High-Z State for TTIP and TRING
- 50mA (rms) current limiter
