NOTE

If the faceplate of the MPDM reads ACCUNET, then the D-kit has already been
installed and you should not need to modify the MPDM in any way. In this case, skip
to step 2.

a. Install the 56 Kbps D-181509 kit by following the instructions included with the kit. The D-kit

is used to modify the MPDM so it will work with 56 Kbps facilities.

b. Install the V.35 DTR card in the MPDM. The V.35 card allows a call to be answered without

an attached DTE device.

To see if the V.35 card has already been installed, power up the MTDM without having a DTE
attached. The Terminal Ready LED on the MPDM will be on if the V.35 DTR interface has
previously been installed.

c. Solder two loops or build and connect a male loopback plug to make the connections shown in

Figure 10-5, V.35 Male Connector.
