Description
The Q48SL12010NRA is a complete selectable E1 or T1 Line Interface Unit (LIU) for short- and long-haul applications. Receive sensitivity adjusts automatically to the incoming 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. The device can generate the necessary G.703 E1 waveshapes in 75Ω or 120Ω applications and DSX-1 line build outs or CSU line build outs of 0dB, -7.5dB, -15dB, and -22.5dB for T1 applications.
Specifications and 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/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 limiterApplication Scenarios
The Q48SL12010NRA can be used in various scenarios, including telecommunications and networking applications where E1 or T1 Line Interface Units (LIUs) are required. It is suitable for both short- and long-haul trunks and supports different line build outs and termination options.
Comparison
The Q48SL12010NRA offers a wide range of features and specifications that make it a versatile solution for E1 and T1 line interface applications. It supports both E1 and T1 signals, with adjustable receive sensitivity and line build outs. It also provides various encoding/decoding options and has a programmable monitor mode for receiver. However, one potential disadvantage is that it requires a 5V power supply.
