TUPP™ 2488 ASSP Telecom Standard Product Data Sheet
Function
Egress Bus Composite Timing Signal. The
Egress Bus composite timing signal, EJ0J1[4:1],
identifies the frame, payload and tributary
multiframe boundaries on the Egress Data bus
EDATA[4:1][7:0]. EJ0J1[4:1] pulses high with the
Egress Bus Payload Active signal EPL[4:1] set low
to mark the first STS-1 (STM-0/AU3) identification
byte or equivalently the STM identification byte
J0(C1). Optionally the EJ0J1[4:1] signal pulses
high with EPL[4:1] set high to mark the path trace
byte J1.
The J0 byte on all 4 streams will be coincident.
Optionally the EJ0J1[4:1] signal pulses high on the
V1 byte to indicate tributary multiframe boundaries.
The V1 indicator on this bus is only valid in
Payload-Processor Loopback in TUPP 2488.
Disable indication of the V1 byte when connecting
the TUPP 2488 to a TUPP 622 or TEMUX 84
devices, as these devices do not require V1
indication.
EJ0J1 [4:1] is updated on the rising edge of
REFCLK.
EJ0J1[4:1] pins are implemented with
programmable drive I/O. They are controlled by
VDDOPROG_E.
Egress Alarm Indication Signal. The Egress
Alarm Indication Signal bus, EAIS[4:1], identifies
bytes of STS-N/STM-M streams that are in high-
order path AIS alarm on the corresponding egress
data bus (EDATA[4:1][7:0]). EAIS[N] is set high to
mark the stream in AIS alarm on the
EDATA[N][7:0] bus except during STS-N/STM-M
J0 and Z0 byte locations when the contents of
EAIS[4:1] is invalid.
EAIS[4:1] also identifies bytes of tributary unit
streams that are in low-order path AIS alarm on the
corresponding egress data bus (EDATA[4:1][7:0]).
EAIS[N] is set high to mark the stream in AIS alarm
on the EDATA[N][7:0] bus.
EAIS[4:1] indicates tributary AIS for all traffic that is
processed through the tributary path of the Payload
and indicates high order path AIS for STS-1s
processed through the payload processor bypass
path.
EAIS[4:1] is updated on the rising edge of
REFCLK.
EAIS[4:1] pins are implemented with
programmable drive I/O. They are controlled by
VDDOPROG_E.
