Abstract: A telephony system having automatic timing adjustment for diverse routing of HFC systems has a signal stream routing through a signal line loop between a head-end and at least one communication unit. If a fault occurs within the signal line loop, recognized by the head-end when a short uplink burst from the communication unit does not align within a predetermined timing window, the head-end will cycle through predetermined delay parameters corresponding to various alternate signal line loops made up of redundant signal lines. Once the predetermined delay parameter corresponding to the current alternate signal line loop is determined, normal operation of the system resumes.

Abstract: A method for assigning communication resources includes assigning communication resources (216, 218, 220) in the nature of bandwidth according to various selection schemes based upon the type of communication service being provided, and based upon the nature of the service area (128, 130) and subscriber premises (132, 134).

Abstract: A cable telephony system (100) including a plurality of subscriber units (142) connected to a cable control unit (102) by a cable distribution network (106) in which the cable control unit (102) detects events associated with connections occurring in the cable telephony system. Information describing these events is placed into connection event reports and sent to a traffic analysis and planning system (116) as the events are detected by the cable control unit (102). These reports are used to manage the cable telephony system (100).

Abstract: A method and apparatus for controlling data transmissions from a first communications unit (202) to a second communications unit (210). Data transmissions received from the first communications unit (202) at the second communications unit (210) are processed to determine a power level of the data transmission. In response to a determination that the power level is not within a desired range or operating window (400), an adjustment value indicating the amount of change needed in the power level of the data transmission from the first communications unit (202) to fall within the desired range or operating window (400) is determined. This adjustment value is sent to the first communications unit (202). In response to receiving an adjustment value from the second communications unit (210), the first communications unit (202) adjusts the power level of its data transmissions.

Abstract: A data link control method including receiving a message (30) for transmission over a cable communications system. The method determines a number of octets in the message (30). When the number of octets is less than or equal to a predetermined number of octets, the method sets a frame length (44) equal to the number of octets and transmits a frame (180) containing the message (30). When the number of octets is greater than the predetermined number, the messages (30) is segmented (32-42), each segment being identified in order with respect to the other segments. The method thereby provides for graceful communications resumption when the transmission of a message is interrupted before completion.
