Output Signal - Channel 2; Egress Direction DS3/E3 Frame Genera-
tor Block Framing Pulse Output pin - Channel 11; Transmit STS-1
Framing Pulse Output pin - Channel 10:
See description for Pin # C23 above using the appropriate channel num-
bers.
If STS-3/STM-1 Telecom Bus ((associated with STS-3/STM-1 Channel
2) has been enabled - STS-3/STM-1 Receive Telecom Bus - C1/J1
Byte Phase Indicator Output Signal:
If STS-3/STM-1 Telecom Bus ((associated with STS-3/STM-1 Channel
2) is disabled - RxDS3FP_10 (Receive DS3 Frame Pulse Input/Out-
put - Channel 10):
Output Signal - Channel 3; Egress Direction DS3/E3 Frame Genera-

If STS-3/STM-1 Telecom Bus (associated with STS-3/STM-1- Chan-
nel 2) is disabled then the function of this output pin depends upon
whether Channel 10 has been configured to operate in either the
DS3/E3 or STS-1 Modes.:
