LIMITER DISCRIMINATOR
The Limiter Discriminator (PIN 900-44756-
01) PCC module plugs into the modem shelf. It
converts fm binary or duobinary signals that represent
the information originally modulated by the distant
The REC MODE operating control is located at
the front of the PCC module.
All test pin-jacks are located at the front of the
PCC module.
DECODER ERROR DETECTOR
Decoder Error Detector (PIN 900-44757-01)
PCC module plugs into the modem shelf. It regenerates
signals from the limiter discriminator to a serial-by-bit
NRZ form for driving a receiving data processor. It also
detects data pattern errors and loss of received signals
and provides outputs to peripheral alarm equipment.
All test pin-jacks are located at the front of the
PCC module.
The BIT RATE operating control and the
ERRORS indication lamp are located at the front of the
PCC module.
DIGITAL RECEIVER CLOCK
Digital Receiver Clock (PIN 900-44760-01)
PCC module plugs into the modem shelf. It provides a
clock signal (phase corrected to regenerated data signal
from the associated receiver) for data retiming and for
external clocking functions.
The BIT RATE operating control and the test
pin-jacks are located at the front of the PCC module.
