A system and method for communication allows a V.90 modem located at a customer premises to appear as a "central site" modem to a V.90 "end-point" modem located remotely from the customer premises "central site" V.90 modem. The customer premises includes a communication device that provides a four wire digital connection to the customer premises V.90 modem co-located with the communication device at the customer premises. Because the V.90 modem located at the customer premises has a four wire digital connection to a public switched network, it appears to a remote "end-point" V.90 modem that the customer premises V.90 modem is a "central site" modem. In this manner, a higher data rate is achievable from a customer premises "end-point" modem to either a remote "endpoint" modem or a remote "central site" modem, than is achievable from the "end-point" modem to the customer premises "central site" modem. This results in an upstream data rate approaching 56Kb/s from the customer premises "central site" modem to the "end-point" modem.
