Name
The name of this QPSK.
You can use up to 15 alphanumeric characters. Be sure to use a
name that allows you to easily identify the QPSK modulator and
where it resides.

Be careful to properly place the dots (.) between numbers.
Physical Address
The MAC address for the QPSK.
Subnet Mask
The subnet mask where this QPSK modulator resides.
Default Router
The IP address for the router associated with this modulator.

Frequency
The RF output frequency assigned to this modulator.
This value can be from 70 MHz to 130 MHz in increments of 0.25

DCM (DHCT
Communications Mode)
Communications Mode)
Determines the DCM for the QPSK.
Important: Currently all DSG-capable DHCTs use a Mixed
DOCSIS/DAVIC DCM. Unique code on Explorer 8300 DHCTs
enables them to recognized a DCM of Mixed DOCSIS/DAVIC as
DOCSIS. QPSK modulators that provide the

enables them to recognized a DCM of Mixed DOCSIS/DAVIC as
DOCSIS. QPSK modulators that provide the
Explorer 8300 DHCTs use a DCM of Mixed DOCSIS/DAVIC.
Select the appropriate DCM from one of the following choices:
DAVIC - Select if DHCTs receive all communications
(out-of-band and unicast data) on a DAVIC channel.
Mixed DOCSIS/DAVIC - Select if DHCTs receive
out-of-band data on a DAVIC channel, and unicast
communications on a DOCSIS channel.

DOCSIS - Select if DHCTs receive out-of-band data and
unicast data on a DOCSIS channel. (The DAVIC channel
may be used for out-of-band data if the DOCSIS channel
is impaired.)
