The number that tells you what number you're calling from are ANI or ANAC circuits, not milliwatt numbers. Milliwatt numbers are generally loud, obnoxious continuous tones that continue for several minutes, and then usually break into a series of milliwatt-level bursts. Quiet termination numbers are just silent. Your testing method is close. Dial into a DID on your PRI and have the PRI send Milliwatt(); there is no need to generate it with PlayTones. Adjust the RX gain on your analog line until you get the magic value of 14844. Now the analog RX side is adjusted. Have the digital side call the analog line and have the analog line run Milliwatt(); adjust the analog side's txgain until the digital side reads the same value. I've heard some speculation that setting your txgain this way can result in your transmitted audio being too "hot" -- I've done some relevant searching of the archives but haven't found this reference now, and it's been a good many years since I've had to play with this myself. Give it a go; if you have trouble with people saying you're too loud you can adjust the txgain down some. This is, however, the way I used to do it and didn't have any troubles. -A. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
