unchannelized mode there is no asynchronous state. In general a port is
in asynchronous state when a port is disabled.
A transmit port changes to the asynchronous mode if the number of bits
between two synchronization pulses is not equal to a multiple of the
number of frame bits of the selected mode
Port Number
This bit field identifies the port for which the information in the interrupt
vector is valid.
Synchronization achieved
Port has changed from asynchronous state to synchronous state. This
interrupt is available for ports configured in T1, E1 mode. In
unchannelized mode there is no synchronous state.
A receive port changes to the synchronous state, if the number of bits
between two synchronization pulses generated by the port related
framer is exactly equal to the number of frame bits of the selected mode.
The first framer pulse after a port is enabled causes the receive port to
change to the synchronous state.
Asynchronous state
Port has changed from synchronous to asynchronous state. This
interrupt is available for ports configured in T1 or E1 mode. In
unchannelized mode there is no asynchronous state. In general a port is
in asynchronous state when a port is disabled.
A receive port changes to the asynchronous state if the number of bits
between two framer synchronization pulses is not equal to the number
of frame bits of the selected mode. The synchronization pulses are
generated internally by the T1/E1 framer.
