US Patent:

53848292, Jan 24, 1995

Filed:

Apr 17, 1992

Appl. No.:

7/870621

Inventors:

David W. Heileman - West Chester PA
Tommy L. Bennett - Douglassville PA
Frederick C. Kruesi - Exton PA
Robert A. Latimer - Plymouth Meeting PA

Assignee:

Unisys Corporation - Blue Bell PA

International Classification:

H04M 164
H04M 350

US Classification:

379 67

Abstract:

A platform for supporting telephone network applications includes Network Interface Units (NIU) for interfacing between the telephone network and the platform. A disk storage system stores voice messages to be sent over the network and voice messages received from the network. Voice messages are conveyed between the NIUs and the disk storage system by Voice Interface Modules (VIM). The platform is installed on a general purpose digital computer and includes an Applications Interface Module (AIM) responsive to an AIM command set including: SEND VOICE MESSAGE, CONNECT CALL, COLLECT DIGITS, INITIATE CALL, TERMINATE CALL, GET MESSAGE NUMBERS and PIVOT CALL. In response to SEND VOICE MESSAGE, a designated message stored on the disk system is sent to the network via the VIM. SEND VOICE MESSAGE has a RECEIVE VOICE MESSAGE option whereby a message is received from the network after the SEND data is transmitted and stored on disk. The platform initiates a call to the network in response to INITIATE CALL and an application is informed of an incoming call to the network by an INCOMING CALL Response from the AIM to the application.

International Classification:

G06F 300
G06F 1300

US Classification:

395250

Abstract:

An interface between a real-time data link and a digital computer system utilizes data buffers between the computer central data storage and the data link. An interface control processor is responsive to a Data Transfer Command set comprising a SEND, a GET, a SET-TAG and a TERMINATE command. The commands include a TAG parameter that is set by the SET-TAG command to group sequences of SEND and GET commands so that logical streams of data are continuously transmitted and received across the interface. The SEND command includes a RECEIVE parameter to initiate the transfer of received data from the data link to the buffers after all data associated with the SEND command has been transmitted. Data transmission and reception operations are terminated by a TERMINATE command with a TAG parameter matching the TAG parameters of the sequence of commands controlling the operations. The SEND, GET and SET-TAG commands are stacked in a command queue and applied sequentially to the control processor.
