Setting Up BFS QAM Modulator Basic Parameters in an RCS
Complete these steps to set up the basic parameters for a BFS QAM modulator.
1.
On the DNCS Administrative Console, click the DNCS tab.
2.
Click the Network Element Provisioning tab.
3.
Click QAM. The QAM List window opens.
4.
Click File > New > QAM. The Set Up QAM window opens with the Basic Parameters tab in the
forefront.
5.
Use the following fields when you manage basic parameters for a BFS QAM modulator.
Field
Description
Headend Name
The headend in which this BFS QAM modulator resides.
QAM Name
The name you will use to identify this BFS QAM modulator.
You can use up to 15 alphanumeric characters (for example, HE1BFSQAM).
Be sure to use a name that is consistent with the naming scheme used on your
network map.
network map.
IP Address
The IP address for this QAM modulator.
Be careful to properly place the dots (.) between numbers.
Tip: When entering IP addresses, type a period to move from octet to octet.
Do
Do
not
press the Tab key to move from octet to octet; pressing the Tab key
moves the cursor to the next field on the window.
Modulation Type
The type of modulation standard this modulator uses.
Example: If this is a 256 QAM modulator that uses ITU B modulation, select ITU
J.83 Annex B (6 MHz).
J.83 Annex B (6 MHz).
MAC Address
The MAC address for this QAM modulator.
Subnet Mask
The subnet mask where this QAM modulator resides.
If your system uses a standard network configuration, type 255.255.255.0,
otherwise type the subnet mask as assigned by your system administrator.
otherwise type the subnet mask as assigned by your system administrator.
Default Gateway
If your system uses a default gateway, enter the IP address of the default
gateway.
gateway.
Using a default gateway speeds up the reconnection process that occurs after a
BFS QAM modulator is rebooted.
BFS QAM modulator is rebooted.
Allow SI
Determines whether the QAM carries SI (system information), which defines it as
a Distinguished QAM):
a Distinguished QAM):
Set to yes (selected) if this BFS QAM modulator will also
function as a Distinguished QAM.
Set to no (unselected) if this BFS QAM is being used in an RCS.
SI information is carried by QPSK modulators in an RCS.
Input Port
Defines the interface that connects to this QAM modulator:
If the BFS QAM Modulator connects to a BFS BIG, click the
SWIF option to select the type of card sending BFS data from the BFS
