Answer Problems

Problem
Your modem does not auto-answer incoming calls.
Solutions
1. Make sure the supplied telephone cable is connected to your
modem's LINE jack and not the PHONE jack.
2. Your modem may not be set up for auto-answer. With the
modem in command state, type ATS0=1 and press Enter to
have the modem answer on the first incoming ring To auto-
answer after a specific number of rings, replace 1 with a value
up to 255. Do not assign a value of 0, which turns off auto-
answer, unless your software can respond to the modem's
RING result codes.
3. Check that the DTR LED is ON, and that the AA LED flickers
with each incoming ring. If the LEDs do not respond in this
way, refer to your ZyXEL Modem Reference Manual.
4. Set &D φ and auto answer, if your modem is not connected to
RS232 or DTR is not ready.
Problem
When you receive a phone call, your modem immediately seizes
control of the telephone line.
