Function
Incoming Bus Payload Indicator (IV5[4:1]). This signal locates
the position of the floating payload for each tributary within each of
the incoming SBI/SBI336 or TelecomBuses.
In SBI/SBI336 mode:
This active high signal locates the position of the floating payloads
for each tributary within the SBI/SBI336 structure. Timing
differences between the port timing and the bus timing are
indicated by adjustments of this payload indicator relative to the
fixed bus structure. All movements indicated by this signal must be
accompanied by appropriate adjustments in the IPL[x] signal.
Multiple SBI/SBI336 devices can drive this signal at uniquely
assigned tributary columns within the SBI/SBI336 structure.
For locked TVTs, this signal must either be driven in the same
manner as for floating TVTs or held low.
In TelecomBus mode:
This signal identifies tributary payload frame boundaries on the
corresponding incoming data bus. IV5[x] is set high to mark the V5
bytes on the bus.
IV5[1] can be part of either a 19.44 MHz SBI or TelecomBus when
combined with IV5[4:2] or can be used as part of a standalone
77.76 MHz SBI336 or TelecomBus.
IV5[x] is sampled on the rising edge of SREFCLK.
IV5[4:2] have integral pull-up resistors.
Incoming Tributary Payload (ITPL[4:1]). This signal is used to
indicate tributary payload when configured for TelecomBus and is
unused when configured for SBI or SBI336 buses.
ITPL[x] is set high during valid VC11 and VC12 bytes of the
corresponding Incoming bus. ITPL[x] is set low for all transport
overhead bytes, high order path overhead bytes, fixed stuff column
bytes and tributary transport overhead bytes (V1,V2,V3,V4).
ITPL[1] can be part of either a 19.44 MHz TelecomBus when
combined with ITPL[4:2] or can be used as part of a standalone
77.76 MHz TelecomBus.
ITPL[x] is sampled on the rising edge of SREFCLK.
ITPL[4:2] have integral pull-up resistors.
Incoming Tributary Alarm Indication Signal (ITAIS[4:1]). This
signal indicates tributaries in low order path AIS state for the
corresponding Incoming TelecomBus and is unused when
configured for SBI or SBI336 buses.
ITAIS[x] is set high when the tributary on the corresponding
Incoming bus is in AIS state and is set low when the tributary is out
of AIS state.
ITAIS[1] can be part of either a 19.44 MHz TelecomBus when
combined with ITAIS[4:2] or can be used as part of a standalone
77.76 MHz TelecomBus.
ITAIS[x] is sampled on the rising edge of SREFCLK.
ITAIS[4:2] have integral pull-up resistors.
