the QPSK modulators.
When you reset a QPSK modulator, the DNCS downloads the new QPSK software to
the QPSK modulator and, if needed, to the QPSK demodulator(s). Follow the

Important: Cisco recommends that when you are downloading software to the
QPSKs, begin with a test hub or a QPSK with the smallest DHCT population, so that
you can confirm the system configuration without affecting subscribers.
