A personal communication network distribution system includes a predetermined number of node devices, a controller, and a network connecting the controller to each of the node devices. The network carries a time division multiplexed signal having a plurality of channels for carrying digital communication information signals between the controller and the respective node devices. Each respective node device is assigned a respective predetermined number of the plurality of channels for receiving digital communication information signals from and/or for inserting digital communication information signals into the time division multiplexed signal. The time division multiplexed signal also includes a second predetermined number of non-assigned channels. The controller assigns one of the non-assigned channels of the time division multiplexed signal to one of the node devices for receiving and/or for inserting communication information signals into the time division multiplexed signal based on call activity at the one node device.

System and method for personal communication system dynamic channel

A device for connecting a data device having an analog output to a digital telephone having a base unit and a handset with first analog signals being coupled bi-directionally between the base unit and the handset. The device includes a first input receiving the first analog signals from the base unit, a second input receiving the first analog signals from the handset, a third input receiving a second analog signal from the analog output of the data device, and a switch coupled to the first, second and third inputs for selectively bi-directionally coupling the second analog signal to the base unit and the first analog signals bi-directionally between the base unit and the handset.
