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 haul LBOs are listed as the length of the cable run (in feet) between the router and the local exchange.
