| 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 |
