P300H P300 Series Modem Installation and Operating Handbook Page 199
If the features are still in use when the time limit expires then the modem will change it's configuration so
it does not require the features which have timed out, and if this in turn causes a change to the
transmitted carrier then the carrier will be muted. A message stating Features not available will then be
displayed showing the letters corresponding to the features, which are no longer available. If for any
reason you need to keep a modem configuration after timeout (eg to re-use it), then use the
configuration memories to store the current configuration before it times out and is changed, and recall it
after the features are available again (eg if you instigate a feature test or have a feature code upgrade).
Please refer to Appendix C2 (previous page) for a description of the feature list (shown as a series of
letters) on the equipment display.
APPENDIX C3: FEATURES ON DEMO EXPIRE SOON
** IF YOU HAVE BEEN REFERRED TO THIS SECTION BY A MESSAGE **
** ON THE EQUIPMENT DISPLAY, THEN THIS IS VERY IMPORTANT **
The modem is warning you that at least one of the features the modem is using in order to
operate as configured is due to expire soon. This means that after expiry, it will cease to function
as configured, and one or several of the features required for how it is currently configured will
no longer be available.
This
Temporary
Features mode is usually used to allow customers to evaluate features (eg Drop/Insert,
Reed-Solomon) for a finite duration after which the modem reverts back to its standard feature set.
Please refer to section C2 to further explain this topic and a description of how to determine which
features are required in order to continue operation.
!! DO NOT IGNORE THIS MESSAGE!!
APPENDIX C4: ASYMMETRIC LOOP TIMING
All P300 Series modems
have this asymmetric loop timing facility.
APPENDIX C5: UPGRADE AVAILABLE
Again this section is not applicable to the P300 series modems.
APPENDIX C6: FEATURES NOT AVAILABLE
You have been directed to this appendix by a message on the equipment display, as the unit has
detected it has been configured to use features, which it cannot provide. This is as a result of one of the
following:
1) It has been programmed over the remote M&C to use features, which it cannot provide. This
cannot happen with local control, as locally the configuration screens do not show features,
which are not available.
2) It was configured to use a certain feature, which is no longer available (see
Temporary
Features or
Test
Features in Appendix C2)
