SYSTEM TESTS

TEST INCOMING DID TRUNKS

You can test DID trunks by establishing a connection on each DID trunk and then busying it out so that all DID trunks can be tested.

1.At a working voice terminal, go off-hook, dial the CO trunk access code, and then dial a DID number.

You should hear ringback at the calling terminal and ringing at the called terminal.

2.At the called terminal, go off-hook and verify transmission.

3.At both terminals, lay the handsets down so that the call remains active. If using a multiline terminal, put the call on hold and place another call (step 1).

4.Place a second call from another terminal to another DID number in the system and verify transmission.

5.Now, place as many calls as there are DID numbers in the system (alternating terminals and numbers). Verify transmission in each c a s e .

6.At all voice terminals used for this test, go on-hook.

7.If there are not enough dial-up CO trunks, work with the CO to check all trunks or have someone call from the outside to check each DID trunk.

TEST INCOMING TIE TRUNKS

1.At the other tie trunk site, go off-hook and access a tie trunk. To test a dial repeating tie trunk, dial a System 25 voice terminal. (No dialing is required to test an automatic incoming tie trunk.)

You should hear ringback at the distant terminal and ringing a t the called terminal (with incoming tie trunk appearance).

2.At the test terminal, go off-hook and verify transmission.

3.At the test and distant terminals, go on-hook.
