Abstract: Assigning inbound ringing ISDN channels to a particular endpoint's call uses a framing listening technique to distinguish between H.221 framing, master bonding channel framing and slave bonding channel framing. If the channel is receiving Master Bonding Channel framing, the MCU detects that this is a new call from a unique far endpoint and may then begin a process to address this new call. If the channel is receiving Slave Bonding Channel framing, the MCU then transmits a multi-frame pattern and looks for a Physical Video Unit Identifier the MCU sent to this far end via the Master Channel upon initial negotiation. If the channel is receiving H.221 framing, a H.243 terminal address assigned using a Terminal Indicate Assignment (TIA) message in the initial channel is used. The far endpoint may then send this address in its additional channels through the use of a Terminal Indicate Additional Channel X (TIX) message.

Abstract: A duty cycle management system and method for use in a wireless device having a transmitter which transmits packets in the form of individual packets and/or packet bursts. A controller in combination with an instruction set limits the number of packets transmitted during each time period defined by one time window or adjacent time windows, on a sliding basis, so as to limit the duty cycle of transmissions during successive adjacent time windows to the predetermined duty cycle limit. To do so transmission of packets is delayed as needed to establish sufficient idle period(s) during the one or adjacent time window(s) to maintain the duty cycle within the duty cycle limit.

Abstract: A data transmission method in a mobile communication system is provided for transmitting user data via a common channel when the user data is generated in a suspended state. In a first embodiment, the method includes comparing a length of the generated data with a reference length for normal data transmission in an active state. When the generated data is shorter than the reference length, a generation frequency of the data generated in the suspended state is compared with a reference generation frequency for normal data transmission in the active state. If the generation frequency of the data generated in the suspended state is lower than the reference generation frequency, a transition to a burst substate occurs to segment the data by a frame length of a common traffic channel and then the segmented data is transmitted via the common traffic channel. However, if a burst substate does not exist, the segmented data is transmitted via a previously assigned common traffic channel.
