Figure 64 Illustration of the “Near-End” Receive STS-3 TOH Processor block receiving an STS-3 frame
(from the remote LTE) with an incorrect B2 byte
Figure 65 Illustration of the “Near-End” Transmit STS-3 TOH Processor block, transmitting an STS-3
frame (to the remote LTE) with the REI-L bits being set to “2”
For information on how the Receive STS-3 TOH Processor block processes the REI-L bit-fields, within each
incoming STS-3 frame, please see Section _.
2.2.9.5.5
The Transmit STS-3 TOH Processor block permits the user to transmit Section Trace Messages to the
remote LTE via the J0 byte. The Transmit STS-3 TOH Processor block permits the user to accomplish this by
either of the following options.
