Overview
Introduction
In earlier system releases, customers could only assign channel maps to a Digital
Home Communication Terminal (DHCT) based on the hub where the DHCT was
located. At that time, all of the DHCTs in any hub shared the same channel map.
However, beginning with Cisco Resident Application (SARA) version 1.58, DVR
version 1.5, or HD version 1.5, you can use enhanced channel maps to provide
greater flexibility in assigning channel maps. For example, you can now add a
channel that is visible to all high-definition (HD) DHCTs but does not appear on
standard-definition (SD) DHCTs.

It is also possible to set up enhanced channel maps manually using SR 2.5/3.5/4.0 or
earlier. To use this approach, you must associate channel maps with a “Virtual
Hub.” See Create Group Definition Rules Manually in SR 2.5/3.5/4.0 and Earlier (on
