How Do I Configure a Churned Set-top to Be Instastaging Capable?
Simply take the set-top out of service. When the admin status is changed to out-of-
service, the DNCS will clear the IP address, delete the secure micro record, and then
change the admin status to “deployed.”
How Long Will It Take the Set-top to Receive EMMs?
Set-tops should receive EMMs within approximately 5 minutes. This time may vary
based on system traffic.
When Instastaging Is Used, What Happens with Respect to IPPV (Credit Limit and Purchase Limit)
and VOD Related Settings, Such As the DIS Enable Flag)?
It is it critical to set these settings at the same time that the set-top is placed in either
two-way status or deployed status. It is especially important to set the Digital
Interactive Service (DIS) Enable flag at this time so that the DNCS will create the
Session Based Encryption (SBE)-related EMMs.
What Is the Network Traffic Impact?
Instastaging can actually improve network traffic overall, especially when you use
Instastaging for two-way staging in the warehouse. In this case, the EMMs only need
to be sent to the one QPSK modulator feeding the staging rack, rather than every
QPSK modulator if you were previously staging in a one-way environment.
