INSTALLING THE DX-120 DX-120 Installation and Maintenance Manual

- 46 -

KSU Wiring

The 408M/E, APM4, COM4, and DPM8 are equipped with RJ-11 modular jacks for each of the interfaced ports.

This connection scheme allows for two methods of installation. The first method (traditional “MDF”) is

recommended whenever possible to allow for maximum serviceability.

CAUTION

System power must be OFF before you plug in the station cable or while servicing port

connections at the punch-down block (66M1-50). Although each port is over-current

protected, unnecessary shorting should be avoided.

EXTENDING PORTS TO THE MDF

• Whenever you extend the various ports of the DX-120 to the MDF, you must extend modular-ended cables

from the KSU module port to the MDF connection block. You have many choices when completing these

connections; it is left to the your discretion to use the most suitable industry-standard wiring practice for the

particular installation.

CAUTION

Use a quality crimping tool to fasten the modular connector to the cable pair when using

field-crimped modular connectors. Use of an inferior crimping tool can lead to bad

connections.

• Many third-party vendor products are available to aid in this installation procedure. The following examples

are readily available at communications equipment / accessories supply houses. Although this example

denotes product of The Siemon Company®, you are urged to investigate the various products available and

make decisions for use based on your own assessment. Vertical is not responsible for the performance of

any product provided by a third-party (outside) vendor.

EXAMPLE

The examples in the following chart are 25 pair (UTP), USOC, 24 AWG cables

pre-fitted with modular connectors on one end of the cable, and a male or female

AMP® type connectors on the other end for termination on a specially equipped,

66-block with mating AMP® type connector.

• When you are finished with the KSU wiring, you can individually isolate each port of the DX-120 system for

independent maintenance needs. Terminate the wiring in place onto a 66M1-50 – connector block. Extend

ports from this connector block to station cables using standard jumper wire.
