Displaying DHCT Sign-on Data for All QPSK Modulators and Demodulators
Follow these instructions to use the listQpsk utility to display DHCT sign-on data for
all QPSK modulators and demodulators.
1 If necessary, open an xterm window on the DNCS.
2 Type listQpsk and then press Enter.
all QPSK modulators and demodulators.
1 If necessary, open an xterm window on the DNCS.
2 Type listQpsk and then press Enter.
Result: The xterm window updates to list the following information:
Each QPSK, identified by ID and name
The demodulators associated with each modulator
The number of IS2W DHCTs associated with each QPSK
Note: IS2W is an acronym for in-service, two-way. This figure represents the
number of DHCTs that have attempted to sign on to the network through the
associated QPSK.

Note: QPSK modulators without an associated demodulator have been assigned
DHCTs that use the DOCSIS sign-on method. DHCTs that use the DOCSIS
method to sign on to the network do not require a demodulator.
