Overview
Introduction
Prior to System Release (SR) 4.2, 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 SARA version 1.58 and later, DVR
version 1.5.x and later, or HD version 1.5.0 and later, you can use enhanced
channel maps to provide greater flexibility in assigning channel maps, including
support for Advanced DOCSIS

Set-Top Gateway (ADSG).
With ADSG support you can deploy ADSG DHCTs. These DHCTs contain a cable
modem that operates with a qualified DOCSIS 1.0 and 1.1 and DSG Cable Modem
Termination System (CMTS). As a result, you can support IP-based, real-time,
two-way communication between these DHCTs and your headend and provide a
faster out-of-band path for two-way services.
