19 (0.9mm) and 26 AWG (0.4mm). Leased circuits that run through signal equalization equipment are not acceptable.
2.The Model 2172 is equipped with either an RJ-45 or a terminal block interface jack that can be used on the CopperLINK interface. These CopperLINK interfaces are a two-wire interface. Observe the signal/ pin relationships on the Model 2172's CopperLINK interface jacks.
The Line port has been classified as TNV-1 and is approved for connection to a PSTN TNV-1 circuit.
WARNING
The RJ-45 connector on the Model 2172's twisted pair interface is polar- ity insensitive and is wired for a two-wire interface. The signal/pin rela- tionship is shown in Figure 3.
