SDH and SONET TX signals

• Generates a STM-64 signal conforming to ITU-T recommendation G.707.
• Generates an OC-192 signal conforming to the Bellcore-GR-1377 standards.
1.3.1

STM-64 TX signal

STM-64 signal formation:
• one AUG1 signal (STM-1 level), generated internally x 64 (64 x AU-4 or 192 x AU-3)
• one AUG4 signal (STM-4c level)
• one AUG16 signal (STM-16c level)
• one AUG1 signal (STM-1 level), generated internally (AU-4 or AU-3), the other
63 AUG1 signals loaded with HP-UNEQ
• one AUG4 signal (STM-4c level)
with HP-UNEQ
• one AUG16 signal (STM-16c level)
with HP-UNEQ

• one STS-12c signal
• one STS-48c signal
• one STS-1 signal, generated internally, the other 191 STS-1 signals loaded with UNEQ

Scrambling

Scrambling is as per ITU-T recommendation G.707, ANSI Standard T1.105 and
Bellcore GR-253.
The scrambler cannot be switched off.
