Figure 13 indicates the Receive Section consists of
the following blocks:
AGC/Equalizer
Peak Detector
Slicer
Clock Recovery PLL
Data Recovery
HDB3/B3ZS Decoder
The purpose of the Receive Section is to take an in-
coming attenuated/distorted bipolar signal from the
THE RECEIVE SECTION
line and encode it back into the TTL/CMOS format
where it can be received and processed by the Termi-
nal Equipment.

The design of the Receive Circuitry should be trans-
former-coupled to the Receive Section to the line.
The specification documents for E3, DS3, and STS-1
all specify 75 Ohm termination loads when transmit-
ting over coaxial cable. The recommended method to
interface the Receive Section to the line in a manner
is shown in Figure 22.
