Abstract: A method and system for optimizing a configuration of mediation devices in a telecommunications central office. Specifications associated with mediation devices are provided. A configuration of mediation devices and legacy devices in a central office is generated. A specification is compared to an attribute of a mediation device in the configuration. The attribute is one of: (1) a distance between the mediation device and a legacy device to be connected to the mediation device, (2) an amount of data to be received by the mediation device from one or more legacy devices to be connected to the mediation device, and (3) a count of one or more legacy devices to be connected to the mediation device. The configuration is updated in response to the comparing of the specification to the attribute. The updating of the configuration provides an optimized number of mediation devices.
