3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC
Table 20
(when configured to operate in the STS-3/STM-1 Mode).
In the Transmit STS-1/STM-0 Telecom Bus Interface, all of the signals (which are input via this Bus Interface)
are sampled upon the rising edge of TxA_CLK (6.48MHz clock signal).
Figure 20
will be received by the Transmit STS-1/STM-0 Telecom Bus Interface.
