Setting Session-Based QAM TSID Ranges
Setting Session-Based QAM TSID Ranges
Background
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:

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.
