Data Characteristics; Tado Data Characteristics - Northern Telecom Meridian M3000 Reference Manual

3-2 Performance specifications
The maximum loop length assumes no under-carpet cable. With
under-carpet cable, the maximum allowable loop length must be reduced
using the following equation:
LM = (14 - (UC x UL)) / 14
where:
