Fitting the Line Isolation Unit
(Refer to Detail A)
1. Remove 4 screws securing top and bottom covers on the 8571 Remote Control Interface and remove the covers.
2. If converting from an existing 2W configuration to a 4W configuration, remove 2 screws securing type 8807 Line
Isolation Unit to chassis on appropriate line position. Disconnect plug connector from the backplane and withdraw unit.
3. Fit 8 pin connector on loom 08-04152 (ITEM 2) to line "X" (where X is 1 - 4) cut-out in chassis rear panel.
4. Fit 4 wire interface PCB assembly 08-03995-001 (ITEM 1) to chassis positioned according to the line being fitted
using 4 screws (ITEM 4).
5. Fit loom 08-04152 (ITEM 2) to 4 wire interface PCB assembly connector ensuring red dot on the connector aligns as
shown.
6. Fit loom 08-04153 (ITEM 3) to 4 wire interface PCB assembly & backplane PCB connector corresponding to the line
being fitted. Ensure that the red dots on the connectors align as shown.
7. Ensure line disable link(s) are in place on backplane PCB corresponding to number of lines fitted. (In accordance
with the Configuring the Interface Line Links instructions.
8. Fit top and bottom covers to 8571 Remote Control Interface and replace screws.

Configuring the Interface Line Links
The interface circuits on the backplane can be set up for two or four line connections.
(The interface is set up at the factory for the appropriate number of lines, either 2-wire or
4-wire interface units).
If four lines are required, an additional dual line equalisation card (CODAN part no.
08-03905-002) can be fitted, allowing up to two more lines (refer CODAN drawing
08-05994). Unused lines should be disabled to prevent signal interference.
Refer tables 1 & 2 for correct link configurations.
The lines are disabled by a link on the interface backplane PCB assembly 08-05995, as
shown in the Backplane View (below).
Lines one and two can be disabled by a link fitted to connector P6.
Lines three and four (if fitted) can be disabled by a link fitted to connector P105.
Note: The card is normally set up in the factory. You will only need to alter this if you add or
remove lines.
