Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

This section describes how to modify service groups, which are used to provide VOD and other interactive
services to subscribers.

After a service group has been saved in the DNCS, you can modify many of its parameters. For example, you can
add a QAM modulator to the service group by selecting the modulator's RF output ports the VOD service will use.
If your site uses generic QAM modulators, you can use the same method to add generic QAM modulators to
service groups. However, to change the name or identifier (ID) of a service group, 

 and

then add the service group again. When you add the service group back to the DNCS, use a new name or ID for
the service group.

Complete these steps to modify a service group in the DNCS.

1.

On the DNCS Administrative Console, click the DNCS tab.

2.

Click the Network Element Provisioning tab.

Click Service Group. The Service Group Data window opens.

7.

Make any of the following changes. For assistance with any of the fields, see Edit Service Group

Settings.



If this is a child service group, you can change the Parent ID and make this service group the

child of another parent service group. Or, you can enter a Parent ID of 0 to make this a
standalone service group instead of a child service group.

Important:  Make certain that this field contains only numerical characters and that the field
contains no leading or trailing spaces. Entering alphabetical characters or a leading or trailing
space in this field can cause the service group and associated resources assigned to the service
group to become non-editable or non-viewable.



For a parent, standalone, or child service group, you can change the RF ports that the service

group uses by adding or removing RF ports:



To add RF ports to the service group, select a port in the Available Ports and click Add

. The selected port moves from the Available Ports list to the Selected Ports list.



To remove RF ports from the service group, select a port in the Selected Ports list

and click Remove. The selected port moves from the Selected Ports list to the
Available Ports list.

8.

When you finish making changes, click Save . The system saves the new service group information in

the DNCS database. The Service Group Data window updates to include the new service group
information.

9.

Update your network map to reflect these changes.
