New features for this release are described in this section. 

 

VTC ID Management is an enhancement of package management in DTACS 1.2 that 
lets operators map any VCT to multiple package combinations. The VCT_ID is also 
used for DTA authorization. 

For configuration instructions, see VCT Provisioning in the Online Help. 

Notes:  

 

The DTACS will not allow duplicate package combinations 

 

When sources are deleted from the DNCS, channel maps on the DTACS must be 
updated with the new source information. This requires database 
synchronization. For this reason, operators should be required to synchronize the 
DTACS database after making changes to sources on the DNCS. 

 

DTACS 1.2 lets operators configure BSGs (Broadcast Service Groups) to localize 
QAMs. A BSG is a group of QAM channels that service a subset of the DTA device 
population. A QAM channel cannot be associated with more than one BSG. All 
QAM channels within a BSG illuminate a single RF plant. 

For configuration instructions, see BSG Provisioning in the Online Help. 

Notes: 

 

BSGs are analogous to hubs on the DNCS 

 

The DTACS leverages channel maps created on the DNCS 

 

DTACS 1.2 provides the Universal Controller Location ID option, which when 
selected, activates a plant split/merge mode. In this mode, the Location ID is set to 
zero for all site announcement messages, while configuration messages continue to 
be sent with the configured Location ID. 

For configuration instructions, see System Configuration in the Online Help.
