Additional bandwidth is provisioned to layer 2/3 networks by initially provisioning optical wavelength channels to meet incremental needs for additional capacity. When bandwidth requirements grow large enough, a wavelength-sized channel is provisioned to meet the bandwidth needs, and the previously provisioned optical wavelength channels are freed up to be reused for additional growth. The optical wavelength channels may be channelized VLANs mapped to resizable optical channel data units such as ODUflex units.

Layer 1 fast provisioning and right sizing of bandwidth for layer 2/3

Telecommunications switching systems that require real-time computer control can be controlled using remotely located computers coupled to the switching systems via data links. By coupling several switching systems to one or more centrally located control computers, maintenance staffing can be reduced while increasing overall system reliability by providing back up control computers in multiple centralized locations. Centrally located control computers can be backed up with redundant computers at the central control site.

Method and apparatus for a remote signaling and call processing in a telecommunications network

The present invention is a method and apparatus for providing prepaid card service to customers for placing telephone calls without relying on a post-service billing model. A service management computer having access to a card database is connected to the network only by out-of-band connections. A voice response unit or a tone receiver and announcement player in the network are the voice interface with the customer and are provided at the originating switch in the network to eliminate multiple switches from the call path.
