Upgrading the QAM Modulator With QAM Software Version 2.3.5 

2-27 

 Continued 

Important:  Resetting a QAM interrupts all active sessions on the QAM for up to 10 

minutes. Complete this task during a maintenance period whenever possible.  
Note:  After resetting the QAMs, select one of the following options: 
• 

For QAM modulators that carry broadcast sessions, go to Verifying the 

Functionality of QAM Modulators That Carry Broadcast Sessions, next in this 

section. 

• 

For QAM modulators that carry xOD or VOD sessions, go to Verifying the 

Functionality of QAM Modulators That Carry xOD or VOD Sessions, later in 

this section. 

Follow these steps to confirm that a DHCT downstream of the QAM modulator can 

tune to authorized channels. 

1. 

Access a DHCT that is connected downstream of one QAM modulator. 

2. 

Refer to the Channels, Sources & Sessions Report that you generated and 

saved in the Determine Existing Broadcast Sessions section, earlier in this 

chapter, to verify restored QAM channels and sessions. 

3. 

Tune the DHCT to each channel listed in the report for each QAM that you 

reset and upgraded. 

4. 

Are all channels listed for the reset QAMs accessible from the DHCT? 
• 

If yes, go to step 5. 

• 

If no, do not attempt to upgrade the software of any additional QAM 

modulators, contact Cisco Services. 

5. 

For those QAMs that carry objectionable material, Cisco recommends that 

you verify encryption with one of the following methods: 
• 

Using a set-top that does not contain subscription service packages, tune 

to the respective channels and verify content is not viewable. 

• 

Verify that the program count is correct on the QAMs that carry 

objectionable material. 

• 

Using a QAM tuner television, tune to the respective channels and verify 

that objectionable content is not viewable.
