<p>A method and apparatus for augmenting the capacity of a bidirectional confirmed delivery transmission circuit (20) using a secondary unidirectional data delivery cirucit (22). A network point of presence (10) accesses a computer service (24) through a trunk connection (16). An endpoint (14) accesses the computer service (24) through the point of presence (10) using two-way communications on a primary circuit (20). Saturation of the primary circuit (20) is detected by the network point of presence (10) which alternataly routes selected communication data through a secondary network headend (12) on a data link (18) to be sent to the endpoint (14) on a secondary circuit (22).</p> |
