3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC
Figure 18 presents an illustration of the waveforms of the signals that will be output via the Receive STS-1/
STM-0 Telecom Bus Interface along with the timing parameter (t12).
NOTE: The value for t12 can be found in
1.4.3
The Receive STS-1/STM-0 Telecom Bus Interface Timing (for Channel 0 when configured to
operate in the STS-3/STM-1 Mode)
In the Receive STS-1/STM-0 Telecom Bus Interface, all of the signals (which are output via this Bus Interface)
are updated upon the rising edge of RxD_CLK (19.44MHz clock signal).
Figure 19 presents an illustration of the waveforms of the signals that will be output via the Receive STS-1/
STM-0 Telecom Bus Interface, associated with Channel 0, whenever it is configured to operate in the STS-3/
STM-1 Mode.
