Function
Transmit Payload Indicator (TV5). The transmit payload indicator
(TV5) locates the floating payload on the SBI336 or TelecomBus
when configured for the transmit byte-wide interface.
In SBI336 mode:
This active high signal locates the position of the floating payloads
for each tributary within the SBI336 structure. Timing differences
between the port timing and the SBI336 bus timing are indicated by
adjustments of this payload indicator relative to the fixed SBI336
structure. All movements indicated by this signal must be
accompanied by appropriate adjustments in the TPL signal.
In TelecomBus mode:
This signal identifies tributary payload frame boundaries on the
transmit parallel data bus. TV5 is set high to mark the V5 bytes on
the bus.
TV5 is updated on the rising edge of SYSCLK.
Transmit Tributary Payload (TTPL). This signal indicates valid
tributary payload data when configured for transmit byte-wide
TelecomBus interface.
TTPL is set high during valid VC11 and VC12 bytes. TTPL is set
low for all transport overhead bytes, high order path overhead
bytes, fixes stuff column bytes and tributary transport overhead
bytes (V1,V2,V3,V4).
TTPL is held low in SBI336 mode.
TTPL is updated on the rising edge of SYSCLK.
Transmit Tributary AIS Indicator (TAIS). This signal indicates
tributaries in low order path AIS state when configured for the
transmit byte-wide TelecomBus interface.
TTAIS is set high when the tributary on the transmit bus is in AIS
state and is set low when the tributary is out of AIS state.
TTAIS is held low in SBI336 mode
TTAIS is updated on the rising edge of SYSCLK.
