Tone Generator Adjustment:

- Generate a tone test sequence using RLC-3 command 040:

040 2000 0001 1000 D or unkey or <Enter> will generate a 1000Hz tone for 20 seconds

- Adjust "TN" pot on the RLC-3 port card to the desired deviation

- 1.5Khz deviation is typical

Step #6: Connect the Autopatch to the RLC-3

The autopatch is normally mounted inside the RLC-3's rack cabinet, near the main power jack. The

autopatch has a separate power jack to make it easier to radio remote the patch (discussed in the

next paragraph. You should run a separate power cable to it. Then use the included DB-9 male to

DB-9 female cable to connect the autopatch to one of the radio card's lower DB-9 connectors (the

same connector you used for your repeater, but on a different radio card). Plug your phone line

into the RJ-11 connector and the patch is ready. The phone line can be split if needed, with one

line going to the controller and the other to a telephone, modem, answering machine, etc. Note:

the switches on the radio card that the autopatch is plugged into should all be off (no deemphasis

filter, COR and PL active low).

Adjustment:

Since every phone line is different, it is easiest to just adjust the autopatch until it sounds good

rather than to some specific level. Use command 110 to enable the autopatch, then enter 111 from

a radio port and unkey. You should hear dial tone. If you do not, either something isn't hooked up

right, or the levels are turned all the way down. Entering 114 and unkeying will hang the patch up.

Once you get dial tone, try entering the phone number of someone that can help you set the levels.

As soon as you press the first digit of the phone number, the dial tone should stop and after you

enter the number, you should hear the phone ring. If either the dial tone continues or the phone

won't ring, try adjusting the transmit level pot on the radio card that the autopatch is connected to

and/or the patch audio input pot on the autopatch itself (they control the same level - there are two

pots to make it easy to radio remote). Once you are able to place a call, have the person on the

other end tell you how to adjust those pots so that your voice is the right volume for them. Then

have them talk and adjust the receive level pot on the radio card and/or the patch audio output pot

on the patch itself until their voice is the right volume for you.

The final adjustment is the tone output level pot on the radio card that is connected to the

autopatch. It controls the level of the DTMF digits that the controller generates to dial phone

numbers. To test it, hang up the patch, then enter 113<phone number> and unkey. You will hear

nothing for a few seconds while the controller dials the number, then connects the audio so you can

hear the phone ring. If it doesn't ring or you hear dial tone, adjust the tone level pot on the radio

card until it does dial consistenly. If you can't get it to dial consistently, call someone using

command 111 (unkey and wait for dial tone, key and enter a phone number, wait for them to

answer) and use command 031 to send DTMF digits. They should be able to tell you whether the

digits sound too loud or too soft.

Radio Remoting the Autopatch:

If you do not have a phone line at your controller site, it is possible to radio remote the autopatch

without losing any of the features (forward and reverse patch will still work); in fact the controller

won't even know it is remote. To do this, mount the patch at the remote location where the phone

line is, provide power, and then provide a duplex link between the DB-9 connectors on the patch
