Staff generated Emergency calls shall be treated as the highest system priority. Therefore, all Emergency calls shall annunciate at the top of the call queue of their respective administrative telephone(s). Should that emergency call go unanswered for 15 seconds, the call should re-route to an alternate speaker station then prompt the caller to make a verbal call for help. During the transfer, the original administrative telephone shall continue to ring the distinctive Emergency ring. Should the Emergency transfer to station have an associated administrative telephone, it too shall ring the distinctive Emergency ring.
The Emergency transfer to station shall be field programmable.
Should the original administrative telephone be engaged in a nonemergency conversation, its conversation shall be automatically terminated, indicated with an alert tone, and then reconnected to the station that generated the Emergency call.
Should the administrative telephone be engaged in an Emergency conversation, successive emergency calls shall log into the call queue as well as transfer to the emergency transfer station for their verbal call for help. Upon termination of the initial emergency conversation, the next one shall immediately ring the administrative telephone.
Systems failing to transfer unanswered Emergency calls or failing to immediately connect to the administrative telephone shall not be deemed as equal.
There shall be a system-wide emergency all-call feature. The emergency all-call shall be accessed by dialing "911" from designated administrative phones or by the activation of an external contact closure which shall give the third audio program input emergency status. The Emergency "911" all-call function shall have the highest system priority and shall override all other loudspeaker related functions including time tone distribution.

2.07 VIDEO on DEMAND
1. The system shall provide the capacity to control remotely located
telemedia video sources via any DTMF type telephone in the system
and/or a hand held remote control as the controlling devices or . A
classroom may be equipped with either or both of the control devices.
2. Telemedia video sources, which may be controlled, shall include most infrared controllable; videocassette recorder, video laser disk, DVD, and cable television converter box. The telemedia control panel shall also have the ability to control most infrared controllable; compact disk players, cassette players, AM/FM tuners, or most other infrared controllable source/device.
NOTE: Video sources, television, and an MATV system shall be provided, however, they are specified elsewhere.
3. There shall be LED's mounted on the face panel of the telemedia control panel to indicate that a source has been reserved, power is applied to the telemedia control panel, the telemedia control panel is in the learn mode, or that there has been an error in the programming of the telemedia control panel.
4. The telemedia control panel shall have the ability to learn and reproduce the infrared commands of most sources the user wishes to control. This ability shall not be limited to only VCR's, DVD’s and video laser disk players. As this feature will allow the user to alter or replace any source in the future without the worry of source control compatibility, it is essential that all telemedia control panels submitted include this capability. Those submissions, which include telemedia control devices, which do not have the ability to learn source control commands, will not be accepted as equal to that which is specified.
5. The telemedia control panel shall be a microprocessor based, selfcontained unit capable of learning, storing and then reproducing the infrared control commands of up to four different sources. The telemedia control panel shall be capable of learning, storing, and then reproducing up to twenty different commands for each of the four different sources. The learned commands shall be stored in nonvolatile memory.

It shall be possible to standardize the telephone button/feature assignment of all the different sources to be controlled, example: 1-play, 2-stop, 3pause, 4-rewind, 5-fast forward, etc., for all of the sources. This way, in conjunction with the reconnect command, the user is not necessarily required to be aware of which source they are actually controlling.
This standardized telephone button/feature assignment is crucial to the ease of operation of this system. All submittals shall indicate whether or not the button to feature assignment is a standard function of the system. If it is not a standard function of the system, the submittal shall indicate precisely how this function is to be accomplished. Failure to submit alternate button standardization shall be deemed as being in direct conflict with these specifications and, therefore, not equal to that which is specified.
The system shall be capable of supporting multiple telemedia control panels. It shall not be necessary for the telemedia control panel to be located in the central communications rack.
There shall be an administrative telephone with a plain English menu driven display located in the media center for use by the media center personnel.
This station may have an associated loudspeaker. In addition to the media control features, this telephone shall support all other system feature and functions.
It shall be possible for the media personnel, from their administrative display telephone, to pre-assign any telemedia source to any station. A plain
English menu prompting the media personnel through the various programming options shall aid this pre-assignment. Programming capabilities are review source/station assignment (if any), enter source/station assignment, delete source/station assignment, and exit.
Once a source has been reserved for a station, all other staff stations are completely locked out the control of that source.
After a telemedia source has been reserved for a specific station, that station shall need only to depress their "9" button twice to be (re)connected to their pre-assigned source, thus eliminating the need to remember the telemedia source station number.
Access to a specific telemedia source is achieved, using the classroom telephone, by dialing the extension number of the desired source OR, if preassigned by the media personnel, simply by depressing the "9" button twice.
To (re)connect to the telemedia source the user simply shall remove the telephone handset from its cradle and dial the reconnect code, "99".
Systems, which require the user to remember exactly which source they are to be using, are too complicated and, therefore, in direct conflict with these specifications. Submittal of systems which do not offer the above specified reconnect command shall precisely indicate an alternate method of how the above specified reconnect command is to be accomplished.
Upon access of the telemedia source the user shall receive a continual confirmation beep to indicate continued access and control of the source.
Upon activation of a function, the user shall be sent a double pulse of the confirmation tone to indicate the command was recognized and processed.
16771-32

The user shall be capable of continuing to enter functions as long as they remain off hook.
13. Once the telemedia source has been reserved or accessed, the user may connect and disconnect at their discretion. The user may hand up the telephone without releasing the telemedia source to other users. While the telephone is in the on-hook condition, no link within the system shall be occupied.
14. The telephone and/or speaker shall remain available for all normal station activities and communications while telemedia source reception is in process. Systems which require that a link be maintained throughout the duration of the source use or that restrict the use of any of the stations functions shall not be deemed as equal.
15. Release of the telemedia source shall be accomplished by either the media personnel or the source/station user. It shall be possible to release the source from either location via telephone or manually from the media center.
16. A telemedia source control panel shall be located in the media center to accept direct commands from the classroom telephones and convert them into source control commands. The interface between the telemedia control panel to any of the sources shall not require any modification to the source or the telemedia control panel as this would void any warranty.
17. The telemedia control panel shall be a "smart" device, in that it shall be capable of learning the control commands of most infrared controllable sources. Those systems, which rely on “universal” or preprogrammed type remote controls, are limited to their library of controllable sources and quickly become obsolete.
It is absolutely imperative that the end user maintain the ability to change, replace, or upgrade their sources without having to upgrade or change any other equipment.
All submittals shall indicate if their submitted telemedia control panel is capable of learning infrared control commands. If it is not capable, the submission shall precisely indicate an alternate method of achieving the same result without subjecting the end user to future expenses beyond simple source changes.
18. There shall be a computer and associated software supplied to support a video clock and scrolling message center. These images are to be distributed facility wide via an unused channel on the MATV system.
