Modem with ring detection/modem processing capability
First Claim
1. A modem comprising:
- a ring detector;
a datapump unit capable of processing an incoming telephone call of one of a plurality of communication modes, each communication mode being associated with a ring type; and
a controller coupled to the datapump unit and responsive to the ring detector for;
determining the ring type of the incoming telephone call,setting a group of user-controllable registers based on the ring type, andaccessing the user-controllable registers to configure the datapump unit to process the incoming telephone call in accordance with the communication mode associated with the ring type.

Abstract
A modem which connects to a data terminal is connected to a telephone line capable of supporting multiple directory numbers with each number having a distinctive ring signal. The modem has a ring detector which indicates the presence of a ring signal associated with an incoming call from a remote device. The modem also includes a datapump unit capable of processing analog signals associated with a telephone line and digital data associated with the data terminal. A modem controller determines ring type from the ring signal of the incoming telephone call and alters the processing of the incoming telephone call based on the ring type. To that end, the controller may alter the processing of the incoming telephone call by configuring the datapump unit and/or configuring a controller compression/error-correction module based on the ring type before the incoming telephone call is answered. Further, the controller may direct the routing of the incoming telephone call via the data terminal based on the ring type.

25. A modem coupled to a telephone line capable of supporting multiple directory numbers, each directory number having a distinctive ring type, the modem comprising:
-
a ring detector; a datapump unit capable of processing telephone data associated with an incoming telephone call and data terminal data associated with a data terminal, the telephone data and data terminal data being associated with telephone calls of a plurality of telephone communication modes, each communication mode being associated with a ring type; a switching device coupled to the telephone line such that, in a first configuration, the switching device routes the incoming telephone call to an output port of the modem and in a second configuration, the switching device routes the incoming telephone call to the datapump unit; a controller responsive to the ring detector for; determining the ring type of an incoming telephone call; based on the ring type, setting the switching device to one of the first and second configurations; if the switch is set to the second configuration, at least partially configuring the datapump unit to process the incoming telephone call according to the communication mode associated with the ring type. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A data communication system in which a modem couples a data terminal to a telephone line such that the data terminal is capable of receiving data from remote devices transmitted across the telephone line, the modem comprising:
-
a telephone line interface unit connecting the modem to the telephone line and including a ring detector for determining the presence of an incoming telephone call; a data pump unit capable of processing analog data associated with the telephone line and digital data associated with a data terminal, the analog and digital data being associated with a data terminal, the analog and digital data being associated with telephone calls of a plurality of telephone communication modes, each communication mode being associated with a ring type; and a controller responsive to the ring detector for determining a ring type of the incoming telephone call and, before the incoming telephone call is answered, at least partially configuring the datapump unit to process the incoming call according to the communication mode associated with the ring type and for configuring a controller compression/error-correction module based on the ring type for processing data associated with the incoming telephone call. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)

62. A modem coupled between a telephone line capable of supporting multiple directory numbers and a data terminal, each directory number having a distinctive ring type, the modem comprising;
-
a ring detector; a datapump unit capable of processing telephone data associated with an incoming telephone call and data terminal data associated with the data terminal, the telephone data and data terminal data being associated with telephone calls of a plurality of telephone communication modes, each communication mode being associated with a ring type, and the data terminal being coupled to plural user terminals on a user terminal network; and a controller responsive to the ring detector for; determining the ring type of an incoming telephone call; and providing a message to the data terminal identifying the ring type of the incoming telephone call such that the data terminal can route the incoming call to user terminal associated with the ring type.
