    Abstract: A communication system (101) concentrates the output of variable rate transcoders (XCDRs 203, 206, 209) to realize an increase in T1 Megastream link capacity. Line interface cards (212, 213) multiplex a generic transcoder/rate adapter unit (GTRAU) format to a concentrated transcoder/rate adapter unit (CTRAU) format based on a determined rate of the data being output from the variable rate transcoders (XCDRs 203, 206, 209). An increase in T1 Megastream link capacity is realized by efficiently concentrating full, half, quarter, and eighth rate channels into a single DS0 for transmission over the T1 Megastream.s

    Abstract: A method and apparatus is provided for use in a radio communication system having a first and second base site communication unit (116, 118) operatively coupled to a first and second transcoder (106, 108), respectively. This system also includes a mobile communication unit which is requesting to enter a linked-communication mode with the first and second base site units. In order to perform a linked-communication, a transcoder-base site interface link is established between the second base site and the second transcoder. In addition, the second transcoder is configured to operate in a bypass mode such that it relays information within the transcoder-base site interface link through a communication across regional entity (CARE)-Link in conjunction with a CARE-Control-Link between the first and second transcoder. Finally, the first transcoder is configured to operate in linked-communication mode by relaying information within the CARE-Link which is controlled by the CAREControl-Link.

    Abstract: Power control in a spread spectrum communication system takes place by determining a speed of a remote unit (405) and assigning as a power-control threshold a target threshold based on the determined speed (410). An instantaneous threshold value is created (415) based on frame-quality information and the target threshold. An energy of a power-control group transmitted (430) from a remote unit is compared to the instantaneous threshold value and a power-adjustment command is determined. The power-adjustment command is transmitted to the remote unit instructing the remote unit to adjust its power accordingly.
