Multitech Modem Setup and Configuration Instructions

XX= U-up for 2 wire leased line mode and D-down for 4 wire leased line mode.

iiii) Ideal switch settings for Multi-Tech V32 series modems The settings are the same as the V32L but dip 2

does not change this modem for 2 or 4 WLL operation, this modem only works in 2WLL mode.

*******If your modem is not listed above, you will need to refer to your owners manual for the proper settings

or call Multi-Tech's Technical Support Proffessionals for further assistance or ideas at 1(800)972-2439

4) The next step is to make all the physical connections: The terminals need to be connected to the modems

via the DB 25, 25 pin connector, and the modems need to have the RJ-11 cable connected into the Leased

jack or Line jack if there isn't a Leased jack on the back side of the modem.

2 Wire Leased Line testing: The type of RJ-11 cable you need is a regular POTs phone cable that you would

use to connect your telephone to the wall jack.

4 Wire Leased Line testing: This cable is a normal RJ-11 cable at one end but crossed as follows at the other

end --- if you look at the RJ-11 connector, you can see it has up to 6 physical contacts. Normally RJ-11

phone line jacks use only 4 of those contacts, usually the inside 4. If you count all six positions(even the

empty positions) the wires you will cross will be wires 2 & 3 and wires 4 & 5 at one end only. For example, if

you are holding your connectors with the gold contacts facing you with the locking clip down away from you,

your cable reads across each connector as follows -- yellow - green - red - black and the other connector

reads black - red - green - yellow, now after crossing one end the connectors would read as follows yellow -

green -red - black, and the other would read red - black - yellow - green. That is a 4WLL back to back test

cable.

When the LL cables are connected into the modems and the modems are powered up in about 15 to 30

seconds you should see the following leds on both modems, CD, a baud light(28 or 96 or whatever the

modem supports) TR and possibly EC on or blinking(depending on what you have set in your modem). At

this point you should be able to type on one terminal keyboard and see the typed information come through

on the other terminals monitor .. and do the same on the other keyboard and this screen .... this test shows

that your modem/s does work over a simulated LL circuit that would normally be provided by the phone

company.

5) If the modem connection does not happen, you may have to adjust the dB transmission level by putting

dip number 3 into the up position. If the connection still does not happen then you may have a bad cable or

modem, at this point you may want to contact Mutli-Tech Technical Support at 800-972-2439 for further

assistance.
