Modem Pooling Testing

After assigning modem pooling on System 85 or Generic 2, test the modem-pooling facilities as follows:

1.Use Procedure 100, Word 2 to enable demand testing: On System 85: Set Field 18 to 1 (if it is displaying a 0). On Generic 2: Set Field 7 to 1 (if it is displaying a 0).

2.Use Procedure 646 to test the modem pool:

a. Press NEXT TEST once (Field 1 = 2).

b.In Field 2, enter a ‘0’.

c.In Field 3, enter the digital or analog trunk group number.

d.	Press	NEXT CIRCUIT		until Fields 7 through 11 display the equipment location just added.
e.	Press		. (If the test passes, field 12 will equal ‘0’.)
		EXECUTE

3.Use Procedure 100, Word 2 to disable demand testing (if you changed Field 7 or 18 to 1 prior to testing):

On System 85: Set Field 18 back to 0 (if it was previously displaying a 0).

On Generic 2: Set Field 7 back to 0 (if it was previously displaying a 0).

4.Use Procedure 620 to test the analog facilities: Run Test 2 on the analog circuits (SN243B).

5.Use Procedure 622 to test the digital facilities:

Run Test 2 on the digital circuits (SN270B or TN754).
