Payloads

DS3 Payload

  • General: A single internally or externally generated asynchronous DS3 signal is mapped into an STS-1 payload
  • Frame Patterns: M13, C-bit, unframed
  • Payload Patterns: 223-1, 215-1, AIS, Idle, All Ones

Tributary VT1.5 Payload

  • General: A single internally or externally generated asynchronous DS1 signal is mapped into a specified STS-1 payload virtual tributary
  • Active Channel Pattern: PRBS 223-1, QRW, 3/24, 55 Octet and All Ones
  • Framing: Unframed, SF, ESF, SLC96
  • Modes: Floating, Bit Asynchronous, simplified H4 coding. Bit Synchronous Locked, Byte Floating, Byte Locked.
  • VT Pointer Justification: Positive and negative single justifications. New Data Flag (NDF) operations cause the pointer to jump to a new location.
  • Payload Structure: DS1 payload is mapped into one channel or all 28 channels

STS-c Payload: An internally generated 223-1 PRBS sequence with valid path overhead

 

Alarm and Error Generation
  • Section: Loss of Signal (LOS), Loss of Frame (LOF), BER, Single error inject
  • Line: Alarm Indication Signal (AIS), Far End Receive Failure (FERF), Bit Error Rate (BER), Single error inject
  • Path: Loss of Pointer (LOP), STS Path Yellow, STS Path AIS, BER, Single error inject, Far End Block Error (FEBE)
  • VT: VT LOP, VT Path Yellow, VT Path AIS, BER
  • Alarm Type: Burst or continuous. External TTL event trigger when alarm is activated.
  • Random Bit Error Injection: 1.5 x 10-3 to 10-9 rate or single
  • Bipolar Pulse Violation: 1.5 x 10-3 to 10-9 rate or single

 

Editing
Transport and Path Overhead Byte Modification: All of the overhead bytes, except B1-B3 and H1-H3

Pointer Control: Single positive and negative pointer justification and NDF pointer changes to any value for both SPE and VT

 

General
Frame Detection
  • STS-1: Detection based on A1, A2
