SunriseSignaling Bit Monitor provides simultaneous display of two DS1 streams

  • Displays signaling bits (A-B-C-D) for 24 channels in both directions
  • Displays 8-bit data in both direction
  • Automatic framing to D4, ESF, or SLC-96®
  • Automatic code detection of B8ZS and QRSS (optional)
  • Indicators for standard alarms and errors:
  • LED history mode holds errors or channel seizures for unattended operation
  • Terminated or bridged span connection
Error Monitor Display provides compliance with CCITT G.821
  • Dual input jacks for daisy chaining equipment
  • Access to all error counts (BPV, CRC, Frame, etc.)
  • Access to all error statistics (errored seconds, severely errored seconds, unavailable seconds, etc.)
  • Information available as both counts and rates
  • 24-hour data history in 15-minute blocks
  • RS-232C serial port for remote computer or printer
Audio Channel Monitor allows both sides of a conversation to be checked
  • Single- or dual-direction monitoring is selectable
  • Displays 8-bit data in both directions for selected channel
  • Displays signaling bits for selected channel
  • 0 dBm, 600 Ohm TLP VF output jack and local speaker
