and powei supplies, and

a. Digital Multimeter. A digital multimeter of

mercial quality with an accuracy of + 1.0% or better.

The digital multimeter is used to perform the ground

tests and output voltage tests.

Maintenance Test Phone. For both Dial Pulse (DP) and Dual Tone Multifrequency test set or a single line (MTCE PHONE) is provided on the front PSU for equipped with a modular plug. When the maintenance test phone is not equipped with a modular plug, a station appearance can be used via the Main Distribution Frame to perform the on-line diagnostic tests.

c. Data Service Terminal. A Keyboard-Send-Receive

(MDF).

The

(KSR) daia terminal equipped with a standard ASCII keyboard and an EIA RS-232C interface (Silent 700 Series - Model 743 KSR - Texas Instruments, or equivalent).

Set digital multimeter to appropriate dc voltage scale for the following If further troubleshooting information tests.

To measure the unloaded basic shelf

input voltages, proceed as follows:

a) On basic backplane shown in

Figure 4.00, take reading be- tween

tween terminal El, E2, E3 or PSU. If still out-of-tolerance replace

E4 and ground.

b) On basic backplane connector

J46, shown in Figure 4.00, take

readings beiween pins 2 and 3. If fuse is good, replace -48PSO.

c) Set digital multimeter to

propriate reading between pins 1 and 2 IC fuse on PSU. If fuses are good, of J46.

d) Set digital multimeter to appropri-

ate Vdc scale and take readings

between the following pins on basic backplane connector J47 (shown in Figure 4.00):

1) Pins 1 and 3.

2) Pins 2 and 3.

e) On basic backplane connector

J48, shown in Figure 4.00, take
