3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
Rev.1.2.0.
Figure 62 illustrates the “Near-End” Receive STS-3 TOH Processor block receiving an “error-free” STS-3
frame. In this figure, the locally computed B2 value of “0x5A” matches that received from the Remote LTE.
Figure 63 illustrates the subsequent action of the “Near-End” Transmit STS-3 TOH Processor block, which
will transmit an STS-3 frame, with the REI-L bit-fields (within the M0 byte) set to “0”; to the remote LTE. This
signaling indicates that the “Near-End” LTE has received an error-free Line Overhead and STS-3 Envelope
capacity data in the most recently received STS-3 frame, from the remote LTE.
