Figure 10 indicates the Receive Section consists of
the following blocks:
AGC/Equalizer
Peak Detector
Slicer
Clock Recovery PLL
Data Recovery
HDB3/B3ZS Decoder
In general, the purpose of the Receive Section is to
take an incoming attenuated/distorted bipolar signal
from the line and encode it back into the TTL/CMOS
format where it can be received and processed by the
Terminal Equipment.

tion to the line. The specification documents for E3,
DS3, and STS-1 all specify 75 Ohm termination loads
when transmitting over coaxial cable. The recom-
