Upgrades

When a bridge of the originating party dropped out of a call that had routed off-net with call classification on a non-ISDN end-to-end trunk, the call was torn down. Now, the call is not torn down, but call classification is terminated, the call is left off-net, and it is not redirected to subsequent coverage.

If both CCRON and Answer Supervision by Call Classification features were active on an off-net call, the call did not further redirect to subsequent coverage points.

When an attendant extended a call to a principal with redirected off-net via the CCRON feature, the call did not return to the attendant when the Return Call timer expired.

Integrated Services DIgital Network (ISDN)

To increase the T.305 timer for the Nortel DMS COs, a new protocol version for the US (country code 1) was created. This new protocol version option is labeled as “c.” The new country code/protocol version is automatically assigned a 30-second value to the T.305 timer.

Terminal Translation Initialization (TTI)

Turning off TTI removes ports that are administered by TTI on cabinets that have been removed.

Upgrades from G3V4 07.0.077 or greater to R6.2 have correct defaults for new R6 PPM fields on the DS1 form.
