SDH and SONET TX signals

• Generates an STM-16 signal conforming to ITU-T recommendation G.707.
• Generates an OC-48 signal conforming to the Bellcore-GR-253 and ANSI T1.105 standards.
1.3.1

STM-16 TX signal

STM-16 signal formation:
• STM-1 signal, generated internally x 16 (16 x AU-4 or 48 x AU-3)
• one STM-1 signal, generated internally (AU-4/AU-3), the other 15 tributaries loaded with
HP-UNEQ
• one STM-1 signal, generated internally (AU-4/AU-3), the other 15 tributaries from the
receiver
STM-16c signal formation:
• complete STM-16 signal from receiver
1.3.2 OC-48 TX signal
OC-48 signal formation:
• STS-1 signals, generated internally and STS-1 signals loaded with UNEQ
• STS-3c signal, generated internally x 16
• one STS-3c signal, generated internally, the other 15 tributaries loaded with UNEQ
• STS-1 signals generated internally, the other 47 tributaries loaded with UNEQ
• STS-48 signal from receiver
• one STS-3c signal, generated internally, the other 15 tributaries from the receiver
