Line Status Test

The Line Status Test verifies that the lines assigned to CMS are correctly identified and programmed. It compares the CMS supervisor console with the CMS PC Line Status screen to confirm that they are the same.

IMPORTANT:

Line assignments to both extension numbers assigned to the CMS PC

(CU1 and CU2) must be identical.

IMPORTANT:

If you are not familiar with MERLIN LEGEND system programming, get help with this test from someone who is.

Perform this test at the CMS supervisor telephone (a MERLIN LEGEND System Display Console). Have available the CMS Line Button Planning Form, and MERLIN LEGEND Forms 2a and 2c. If the CMS supervisor phone is located so that you can’t read the PC screen, you’ll need another person to help with this test.

To perform the Line Status Test:

1. At the Initialization screen, press [F3] (System Status).

The System Status screen appears.

2. Press [F5] (Line Status).

The Line Status screen appears.

3. At the CMS supervisor telephone: a. Press the phone’s Speaker button (or lift the handset).

b. Press the line button for the line shown on Button 1 on the Line

Button Planning Form while watching the Line Status screen on the CMS PC.

When you press the line button, the line’s status, as shown on the Line

Status screen, changes from Idle to Cnct (connected).

Line Status Test 7-3

Testing CMS c. Press the Speaker button again (or hang up the handset).

The line’s status, as shown on the Line Status screen, changes from

Cnct to Idle.

d. Repeat steps 3a through 3c for each CMS line.

Each line’s status should change from Idle to Cnct and back to

Idle as you perform steps 3a through 3c.

4. At the back of the CMS PC, reverse the connections to CU1 and CU2 on the CMS card.

5. Repeat steps 3a through 3d.

If, as you perform steps 3a through 3c for each line, the Line Status screen shows either the wrong line’s status change or no change in status for one or more lines, the system has one or more misidentified CMS lines.

To correct the problem:

1.

Exit from Call Management and go to the CMS Main Menu.

2.

3.

4.

Compare the line assignments on your Line Button Planning Form to the line information on MERLIN LEGEND Forms 2a and 2c to make sure that the CMS lines are identified correctly.

Go to the CMS Administration Menu. Display the Administer Lines and

Line Groups screen, and check CMS line assignments. Make any necessary corrections to the line button assignments.

Check MERLIN LEGEND system line programming for the two CMS operator ports (CU1 and CU2) used by the PC.

If their assignments do not match, follow the instructions under “Assign

CMS Lines, External Alerts, and Loop-backs to CMS Supervisor” (see

page 1-16) to:

a. Remove the lines assigned to the two extension numbers assigned to the CMS PC.
