DATA SHEET
- 23 of 96 -
Receive Alarm Indication Port Data: Serial output
leads that provide a 4-bit REI (FEBE) count based on the
received B3 error count, and a Path RDI alarm indication
for a mate TL3M device in a ring configuration, from each
channel. These leads are normally connected to the cor-
responding Transmit alarm indication port data leads
(TnAID) at the mate TL3M device. The receive path over-
head byte clock (RnPOC) signal is used to clock out this
signal. The receive path overhead frame signal (RnPOF)
provides the frame reference. The bits are sent according
to the following format and are repeated every eight bit
times. Bit 1 is the MSB and is the first bit sent.
Transmit Alarm Indication Port Data: These serial
input leads are normally connected to the receive alarm
indication port data output leads (RnAID) at the mate
TL3M device for a ring configuration. Provides an input
for the four bit REI count (received B3 error count), and
the Path RDI alarm indication. The format is shown
above.
Transmit Alarm Indication Port Clock: These clock
input leads are normally connected to the receive path
overhead byte clock output leads (RnPOC) at the mate
TL3M device for a ring configuration. Transmit alarm indi-
cation port data (TnAID) is clocked in on rising edges of
TnAIC.
Transmit Alarm Indication Port Framing Pulse: Nor-
mally connected to receive path overhead byte framing
pulse output leads (RnPOF) at the mate TL3M device for
a ring configuration. Used to indicate the location of the
first bit in the byte.
