Disclosed is a system for an ADSL access network for providing ADSL provision flow control at a DSLAM switch. The system includes an element management system in communication with a DSLAM switch; and a network management system in communication with the element management system, the network management system including a control algorithm for controlling ADSL provision flow on a DSLAM switch by introducing a two level semaphore including a first semaphore and a second semaphore. The first semaphore controls a first provision request flow at the element management system level and the second semaphore controls a second provision request flow at the DSLAM level. Disclosed is also a method of providing ADSL provision flow control at a DSLAM switch. The method includes at a DSLAM switch, receiving a provision request from a network management system; determining whether a DSLAM level semaphore is available at the DSLAM switch; determining whether an element management system level semaphore is available; and connecting the network management system to the DSLAM.

A storage structure includes a plurality of sequentially arranged positions, each position for holding one order at a time. One of the positions is an end position from which an order is to be taken up for provisioning. Each order in a position moves to the next sequential position toward the end position, as the next sequential position becomes empty and available. The positions are organized into a first section and a second section. The first section is distal from the end position and includes at least one position. The first section receives orders from a first order delivery system into a receiving position. The second section is proximate to the end position and includes at least one position. The second section receives orders from a second order delivery system into a receiving position. If the second section cannot receive an order from the second order delivery system due to the receiving position thereof already holding an order, a pre-determined interval is observed prior to attempting to again receive the order. The pre-determined interval is selected to allow enough orders in the storage structure to be taken up and to allow the receiving position of the second section to become empty.
