Ingress Timing for STS-1/STM-0 Applications
Table 13 presents information on the Timing parameters for the DS3/E3/STS-1 LIU Interface Signals (in the
Ingress Direction) for STS-1/STM-0 Applications and when the Receive STS-1 TOH Processor block has been
configured to sample the DS3/E3/STS_1_DATA_IN signal upon the rising edge of DS3/E3/
STS_1_CLOCK_IN.
Table 14 presents information on the Timing parameters for the DS3/E3/STS-1 LIU Interface Signals (in the
Ingress Direction) for STS-1/STM-0 Applications and when the Receive STS-1 TOH Processor block has been
configured to sample the DS3/E3/STS_1_DATA_IN signal upon the falling edge of DS3/E3/
STS_1_CLOCK_IN.
1.3.6
The Egress DS3/E3/STS-1 Interface Timing
The user should be aware of the followings things about the Egress DS3/E3/STS-1 Interface timing.
a. If a given channel is configured to operate in the DS3/E3 Mode, then the DS3/E3 Framer block can be
configured to output the outbound DS3/E3 data (via the DS3/E3/STS_1_DATA_OUT and DS3/E3/
STS_1_NEG_OUT output pins) upon either the rising or falling edge of DS3/E3/STS_1_CLOCK_OUT.
b. If a given channel is configured to operate in the STS-1/STM-0 Mode, then the Transmit STS-1 TOH
Processor block will be operating in the Single-Rail Mode (e.g., the Transmit STS-1 TOH Processor block
will output all outbound STS-1/STM-0 data via the DS3/E3/STS_1_DATA_OUT output pin. No data will be
output via the DS3/E3/STS_1_NEG_OUT output pin).
c. Further, if a given channel is configured to operate in the STS-1/STM-0 Mode, then the Transmit STS-1
TOH Processor block can be configured to output the outbound STS-1/STM-0 data (via the DS3/E3/
STS_1_DATA_OUT pin) either upon the rising or falling edge of DS3/E3/STS_1_CLOCK_OUT.
The Timing Diagram for the Egress DS3/E3/STS-1 Interface is presented below in Figure 17.
