DATA CARD ACCEPTANCE TESTS
Use the following procedures to verify data cards after all the previous T1 unit acceptance testing (electrical con-
nections, system turn-up, control verification and system alarms) has been completed.
7.1
ISDN Card Acceptance Test
Step
Action
System Response
1.
Make sure that the ICB is turned up and operating.
2.
Insert the ISDN card into the appropriate slot of
the ICB.
3.
Enable the NMS or craft interface and verify the
chassis/card configuration with a system that has
been reset to the factory default.
Verify the ISDN card is recognized in the proper
chassis slot and the configuration is 2B+D and
LULT.
4.
Perform a software near-end line T1 loop back.
LOS and ALM LEDs should illuminate on the ISDN
unit.
5.
Connect a test cable to the rear connector of the
full size ISDN card (front connector for a half size
ISDN card) and connect an ISDN NT1 test set (i.e.
TPI 550B) to one of the tip/ring pairs.
Verify that the LOS and ALM LEDs turn “off” and
that no bit errors occur on the test set for the chan-
nel being tested.
6.
Release the T1 loopback.
ISDN card acceptance test is complete.
7.2
DSU Card Acceptance Test
Step
Action
System Response
1.
Make sure that the ICB is turned up and operating.
2.
Insert the DSU card into the appropriate slot of the
ICB.
3.
Enable the NMS or craft interface and verify the
chassis/card configuration with a system that has
been reset to the factory default.
Verify the DSU card is recognized in the proper
chassis slot and the configuration is V.35, and that
the data rate is 64K.
4.
Under DSU settings, enable the latching loopback
option for one channel. Then under the loopback
menu (listed under T1 settings for VT100 craft ter-
minal), perform a DSU near-end latching loopback
with a 2047 test pattern enabled.
Display should show “Map 0” with zero bit errors.
5.
Enter an “R” for release loopback if using a craft
terminal interface. The GUI interface will automati-
cally release loopback after 1 minute.
DSU loopback is removed.
7.3
64XN Card Acceptance Test
Step
Action
System Response
1.
Make sure that the ICB is turned up and operating.
2.
Insert the 64xN card into the appropriate slot of
the ICB.
3.
Enable the NMS or craft interface and verify the
chassis/card configuration with a system that has
been reset to the factory default.
Verify the 64xN card is recognized in the proper
chassis slot and that the configuration is time slot
length of 2, V.35 and the data rate is 64K.
4.
Perform a software near-end line T1 loop back.
No system alarms.
