Abstract:

An automated prefix dialing system is disclosed to allow a subscriber/user to automatically insert a predetermined prefix dialing code in certain outgoing telephone call situations. The system is electrically disposed between the telephone companys central office circuit and the subscribers circuit. The system preferably comprises six sub-circuits: DC power path circuit (off-hook sensor circuit), shadow-ring detector circuit, isolation circuit, DTMF receiver circuit, DTMF generator circuit, and micro controller circuit. When not in use, no power is used by the system. The DC power path circuit, provides power received from the central office line to the various circuits and components of the system when the subscribers phone is taken off-hook. Off-hook sensor circuitry detects when the telephone has been lifted either in response to an incoming call or to initiate an outgoing call. The shadow ring circuit informs the system if the phone is taken off hook because of an incoming call and functions without any power.

US Classification:

719327, 710 1, 710 38, 709230

Abstract:

Provided are a method, system, and program for configuring a device using information from a device table. Device information is obtained for a device coupled to a system. The device information is provided to a device driver executing in the system. The device driver calls a method in response to determining the device driver does not support the device identified by the device information. The method provides device configuration information from a device table to the device driver. The device driver uses the device configuration information in the device table to configure the device for use in the system.

Abstract:

In accordance with a computer program product, apparatus and a method there is provided a redundant network wherein a host computer operates with a plurality of storage devices by monitoring conditions of the multipath storage network and controlling a storage multipath device driver in conjunction with an associated storage multipath device input/output (I/O) pending queue to increase I/O throughput to a storage device driver, such as a disk device driver, when I/O demand increases, and to decrease I/O throughput to the storage device driver in the event of an I/O error condition.

International Classification:

G06F 9/46

US Classification:

719321000

Abstract:

A non-disruptive multipath device driver update system and method are provided. An additional layer device driver is provided between applications running on host system and the multipath device driver such that when an upgrade or update operation is performed on a multipath device driver, the layer device driver redirects I/O operation requests through a standby multipath device driver or an operating system disk I/O device driver. The multipath device driver may then be unloaded and updated without having to experience any downtime since I/O operation requests may still be issued by the applications and redirected around the unloaded multipath device driver. Once the multipath device driver is updated, I/O operation requests may be again routed to the updated multipath device driver and the system may operate in a normal fashion.

Abstract:

A computer program product is provided for extending network services addresses, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, where the program instructions are executable by a processor to cause the processor to identify, by the processor, an event affecting a node, wherein the node provides external access to a network using an Internet Protocol (IP) address, in response to identifying the event, identify, by the processor, an attribute associated with the IP address, and based on the attribute associated with the IP address, determine, by the processor, whether to move the IP address to another node.
