Converter

E1/T1 Cross Rate Converter

  • Enables conversion between one T1 signal and one E1 signal
  • The T1 interface supports D4(SF) or ESF frame formats with B8ZS or AMI line code
  • The E1 interface supports CCS (PCM31) or CAS (PCM30) framing without CRC-4 and framing with CRC-4
  • Configures A-law/μ-law and signaling conversion
  • Supports G.802 Annex B (T1 over E1)
  • Transparent conversion at 64kbps timeslot level
  • 24 time slots of T1 Nx64 can be inserted into E1 Nx64, 30/CAS or
    31/CCS timeslots
  • Controlled slip for buffer over or under flow
