NT1 ACE4 User Manual

Connecting the Terminal Equipment

After successfully powering up the NT1 ACE4, the ERROR indicators should be on and the READY indicators should be flashing. Make sure that terminal equipment (TE) is properly terminated. Plug the TE into one of the S/T con- nectors at the rear of the unit.

The ERROR indicators should extinguish a few seconds after power is applied to the TE. If the ERROR indicators fail to go out, see the section Troubleshooting on page 8.

As the ERROR indicators extinguish, the READY indica- tors should illuminate. There may be a slight delay between the appearance of the READY indicators and the TE’s abil- ity to place and receive calls, depending on the specific TE in use. If the READY indicators fail to illuminate or if you are unable to place or receive calls, see the section Trouble- shooting on page 8.

Typical Configuration

This configuration allows you to connect up to four TEs at

ranges up to 3000 feet from the NT1 ACE4, as shown in Fig- ure 1-6. A termination resistor should be centrally located to

the TEs. The NT1 ACE4 TERMINATION is set to 100 ohms. The TEs should be set to 100 ohms.
