The system for simplified operating system shutdown enables the execution of the required operating system shutdown sequence without requiring the use of a monitor, keyboard, and mouse. This is accomplished by equipping the printed circuit board with a simple switch and an indicator device to provide the user interface to execute the operating system shutdown process. The user operates the switch, which activates the system for simplified operating system shutdown to initiate the required operating system shutdown process. The system for simplified operating system shutdown activates the indicator device in a first mode to notify the user that the shutdown process is now executing. The system for simplified operating system shutdown generates a message, which message is transmitted to the processor. This message comprises a system call for a shutdown and restart. No indication is provided by the operating system to indicate the successful completion of the shut down process, but in the restart process, the operating system generates predetermined POST codes, which are detected by the system for simplified operating system shutdown and used to hold the processor in a reset state. The system for simplified operating system shutdown then activates the indicator device to a second mode to indicate to the user that the operating system is shutdown and the circuit board can be removed from the circuit pack carrier.

In a multimedia communications system where bandwidth of an access facility is limited, the bandwidth is partitioned into three bands dedicated to audio, video and data traffic, respectively, in accordance with blocking probabilities associated with the respective media types. The value of each blocking probability is selected pursuant to the relative importance of the associated media type in a multimedia service. With the blocking probabilities in place, the dominance of traffic of a particular media type, which may be relatively unimportant in the service, would not cause blocking of traffic of other media types, which may be relatively important.

Technique for efficiently allocating bandwidth to multimedia calls in a

An arrangement (FIG. 1) that allows banks (15, 25) of up to eight duplicated active devices (30-37, 40-47) to be connected to a SCSI bus (14) and to share SCSI device IDs, and also allows multiple hosts (10, 20) to share the SCSI bus and the connected active devices. Tri-state buffers (200) act as gates (13, 23, 38, 48) to interface host adapters (12, 24) of a plurality of hosts, and active devices of a plurality of device banks, to the SCSI bus. The gate of only one host adapter and the gates of only one bank of devices are enabled at any one time. Only the devices of the enabled bank can receive and respond to addresses from the SCSI bus, while the devices of the other banks are prevented from receiving and responding to addresses from the SCSI bus. Each host has a tri-state buffer acting as bank selector (16, 26) for selecting one of the device banks, by enabling the gates of the devices of the selected bank through a bank select bus (50). Only one host's bank selector is enabled at any one time.
