T1 service requires the specification of a Line Build Out factor. This parameter modifies the transmitted signal to compensate for degradation due to line losses between the transmitter and receiver. A number of different options are available to meet standards for T1 long haul (direct connection to service providers central office facility), T1 short haul (connection through a local PBX), AT&T TR64211 specification long haul and AT&T TR64211 short haul. Your service provider will tell you which specification their service requires. Short
