* Although the TN1654 circuit pack supports 75 ohms, use the 127A BALUN to convert the 120
ohms to 75 ohms rather than the switch settings.
1
Set the configuration switches on the TN1654 as required per site.
2
Set Switch 6 down (disabled).
Switch 6 may not be present (or active) on all TN1654 DS1 Converter circuit packs.
3
Set Switch 1 up for T1 facilities.
All subsequent facility switch settings (Switches 2-5) reflect T1 framing on each of the 4
facilities. See
4
Set Switch 1 down for E1 facilities.
All subsequent facility switch settings (Switches 2-5) reflect E1 impedance on each of the 4
facilities. See
