In an effort to provide support for table-based Quadrature Amplitude Modulators 
(QAMs), the Digital Network Control System (DNCS) allows you to specify ranges 
of transport stream IDs (TSIDs) that are reserved for session-based QAM 
modulators. This range of TSIDs includes any QAM modulators that are controlled 
by the DNCS and have sessions set up by the DNCS.  All of the following QAM 
types should fall within this TSID range: 

 

QAMs 

 

MQAMs 

 

GQAMs 

 

GoQAMs 

 

Third-party QAMs and Continuum DVP™ eXtra Dense QAM Arrays (XDQAs) 
which adhere to the Generic QAM Interface (GQI) 

This TSID range must not include table-based QAMs, including XDQAs that do not 
adhere to the GQI. 

If you have session-based QAM modulators operating outside of your TSID range, 
the DNCS may be unable to assign the requested resources. If this occurs, your logs 
may indicate that a resource request failed because the network was unable to assign 
the requested resources. 

When you upgrade to system release (SR) 2.7/3.7/4.2 or later, the installation 
process checks to see if you have already specified a range of TSIDs reserved for 
session-based QAM modulators.  If you have not already specified a TSID range, the 
installation process automatically sets the TSID range for session-based QAM 
modulators to 32768 through 65535.
