Abstract
A method of providing a control channel between first and second access terminals in a digital loop carrier, includes forming a pool of channels coupling the first and second terminals wherein each member of the pool can be assigned either to serve as the control channel or as a data channel. A member of the pool is dynamically assigned as the control channel. The control channel can be used to convey information regarding assignment of data channels to handle an incoming or outgoing call.
