4Select the appropriate option to secure the RJ-21 connector to the MBM:

If you are using a straight RJ-21 connector, use the two supplied screws on the sides of the connector to secure it.

If you are using a right-angle RJ-21 connector, use the supplied screw on the left side of the connector to secure the left side of the connector. To secure the right side of the connector, use the supplied cable tie to fasten the 25-pair cable to the anchor on the MBM.

5Connect the other end of the cable to the local connecting blocks.

6If you are connecting extensions to a DSM32, repeat steps 2 to 5 for the second RJ-21 connector.

7Select the appropriate option for your system:

If your BCM50 system has another expansion unit, repeat this procedure if you are adding more extensions or proceed to “Connecting telephone lines to the expansion units” on page 105 if you are adding telephone lines.

If your BCM50 system does not have another expansion unit, proceed to “Connecting the auxiliary equipment”.
