ATT System 25 Installation And Maintenance Manual

							SYSTEM TESTS
SYSTEM TESTS
Once installation is completed, the system must be initialized, following the
procedures in the AT&T System 25 Administration Manual (555-540-500).
When this has been done, the system is ready for acceptance testing. You
should test all trunks, voice terminals, data terminals, and features.
If any equipment does not perform properly, refer to the maintenance
section of this manual for more details.
TEST OUTGOING TRUNKS
You can test all outgoing trunks by using the *2 access code.

an incoming trunk on the system.
3. Answer the call and verify transmission.
4.Go on-hook at both voice terminals.
TEST DS1 INTERFACE
The DS1 Interface feature is tested by making the appropriate type calls that
use the DS1 facilities.Refer to the appropriate section of this manual for
those test procedures.As an example, if the DS1 Interface is used as a Tie
Trunk, refer to the “TEST TIE TRUNK” section of this manual.

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.

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.
At the called terminal, go off-hook and verify transmission.
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).
Place a second call from another terminal to another DID number in
the system and verify transmission.
Now, place as many calls as there are DID numbers in the system
(alternating terminals and numbers). Verify transmission in each
case.
At all voice terminals used for this test, go on-hook.
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.)

TEST 7300H SERIES VOICE TERMINALS
Test each 7300H Series terminal using the terminal’s test switch, by placing
both station-to-station and external calls, and by using the feature buttons.

TEST DIAL ACCESS CODES
1.Using a single-line or multiline voice terminal, verify the proper
operation of each feature requiring a dial access code (Night Service
access code).
2.lf any feature is not working properly, verify the translations at the
SAT.
TEST SYSTEM FEATURES
You can test a number of system features from a multiline voice terminal:
Automatic Route Selection (ARS), Station Message Detail Recording (SMDR),
Direct Group Calling (DGC), System Speed Dialing, PDC login, and Call
Coverage. (Note! You can also use a single-line voice terminal to test all of
these features except for Call Coverage.)
ARS and SMDR Tests
If ARS patterns have been translated, you can test the routing by placing
long-distance calls and checking the trunk indicated on the SMDR output. To
use the SAT to print SMDR records,unplug it from port 1 and attach it to
port 2.
To verify ARS patterns:
1.Determine which long-distance numbers to call by examining the
System Administrator’s ARS patterns.

At any multiline voice terminal, go off-hook, dial the ARS access code,
and dial one of the long-distance numbers. Make sure that the call is
completed before going on-hook.
Repeat Step 2 if additional long-distance numbers must be called.
At the SMDR printer (or SAT), verify that the call was placed over the
correct trunk group.
If not, verify the translations through the SAT.
If the SAT was substituting for the SMDR printer, return the SAT to port

Make additional calls to exercise each member of the complete DGC
group.
Test the DGC dialing announcement (if provided) by making whole group
busy or by logging all members of the group out.
At any voice terminal, dial the DGC access code and go to Step 2.
System Speed Dialing Test
1.From the SAT, determine which numbers have been translated for
System Speed Dialing. (Obtain the list of translated numbers from the
System Administrator.)
2. At any voice terminal, go off-hook, dial a system speed calling code.
Verify transmission and that correct party was reached.
