This indicates where the cable connects in the filter magazine. The filter magazine will contain boards primarily of

the LFU type along with SFU and PFU boards.

The position the LFU7 occupies in the filter magazine. Each slot in the magazine is numbered.

The top half of the LFU7 board. The LFU7 has two connector sections, the top is A and the bottom is B.

The quarter connector position at the rear of the LFU7 where the cable connects. Each connector section

A and B is divided into four quarter connectors. Connector 1 is at the top and 4 is the lowest or last

quarter connector.

The TSR 252 0111/2000 cable plugs into the front of the LFU7 in slot 29 in the top connector section at the lowest

quarter connector position. This is only an example; verify the label on the cable connector at the TLU-63/1 or TLU-

64/1.

3. To verify a call, perform the steps below.

• Ensure that PORT_LOG_CALL is set to TRUE during the configuration file loading (LBI-39040).

• Observe the terminal. The called radio should appear in the LID or GID field. An example is shown below.

CALL:[00003] OUTBOUND DIGITAL LID[06533] [NORMAL_DISCONNECT]:MSC

MSC[01] PBX[01] PHONE[2001] SITES: O[01] D[01]

DUR: 011.50 DATE: 08/20/93 ST: 09:21:37 CON: 09:21:43 DIS: 09:21:49

open closed open - - - - LSB

Switches 4 to 8 are used to define the site ID in binary, with switch 8 as the LSB.

5. Insert the appropriate number of audio boards, with the dip switches set to reflect the number of the card. (See IMC

LBI-38938, Drawing 19D903515 Sheet 3.)

6. Insert the parallel I/O cable on the IMC backplane (JP1xx or JP2xx) from:

Control board to first audio board

First audio board to second audio board

Continuing through the daisy chain until finished

7. Install the concentrator panel for the PIM control card on the IMC interface panel mounting frame. (Note: A

903531P1 audio concentrator is used for the PIM control card and the audio cards. Refer to Figure 2.)

8. Install the concentrator panels for the PIM audio cards on the IMC interface panel mounting frame.

9. Install Cable 19D903628P7x from the IMC backplane to the PIM control concentrator panel at the IMC. (See

Figure 2 or Figure 3 herein for T1 or E1, respectively.) THIS CABLE IS UNIDIRECTIONAL.

10. Install Cables 19D903628P1x from the IMC backplane to the PIM audio concentrator panel at the IMC. (See Figure

2 or Figure 3 herein for T1 or E1, respectively.)
