CRs Corrected in QPSK E14
CR 49349: QPSK stops signing on new DHCTs unless a signed DHCT is released
An issue with QPSK C81 and earlier releases can cause an "artificial sign-on limit,"
an arbitrary sign-on limit for DHCTs, much less than the advertised 16000. In this
condition, the QPSK sets a dynamically reducing limit to the number of DHCTs it
can sign on and hence allocate IP addresses. When this limit becomes less than the
DHCTs signed on to the QPSK, a new DHCT will not get an IP address unless
another DHCT is released.

DHCTs signed on to the QPSK, a new DHCT will not get an IP address unless
another DHCT is released.
This "artificial sign-on limit” takes months to exhibit. Due to a significant reduction
in reboots with C81, this error became more prominent on that release. Replacing
C81 with QPSK E14 fixes this issue.

CR 50664: Possible modulator code download condition
In QPSK C81, QPSK modulators would occasionally lock up if new modulator code
was downloaded due to unintentional reboot during a period of high traffic. In this
situation, the workaround was to revert to the older code from the DNCS, wait 15
minutes, and then intentionally reboot the modulator to download the new code.
This issue has been corrected with QPSK E14.

CR 54139: QPSK modulator Ethernet driver RX can freeze
In earlier releases, the QPSK modulator's Ethernet MAC RX process could freeze. If
this occurred, the out-of-band path was cut off, and the modulator needed to be
rebooted. CR 54139 adds functionality to keep the Ethernet MAC RX process from
freezing.
