Features
:
- Eight channel T1/E1/J1 short haul line interfaces
- Supports HPS (Hitless Protection Switching) for 1+1 protection
- High impedance setting for line drivers
- PRBS (Pseudo Random Bit Sequence) generation and detection with 215-1 PRBS polynomials for E1 without external relays
- QRSS (Quasi Random Sequence Signals) generation and detection
- Programmable T1/E1/J1 switchability allowing one bill of ma- with 220-1 QRSS polynomials for T1/J1 terial for any line condition
- 16-bit BPV (Bipolar Pulse Violation)/Excess Zero/PRBS or QRSS
- Single 3.3 V power supply with 5 V tolerance on digital interfaces...
