Frequently Asked Questions

where port is the port number you have selected. If you do not enter port.log, debug information still appears on your screen, but it is not saved to a log file.

After you finish capturing debug information, you can stop the log program by entering Ctrl-C at the DOS prompt. The log file created is named port.log. If you restart the process without changing the name of the log file, any new debug information is appended to the end of the original file.

Contact Cisco TAC for more information. See the “Obtaining Technical Assistance” section on page xvi for instructions.

You should also have access to a sniffer or LAN analyzer.

Caution For security reasons, Cisco recommends that you do not use the web interface over the public network. Disable the web interface, using the UIPassword parameter, before the Cisco ATA is moved from the service provider site.

Frequently Asked Questions

Q. How can I recover the box if I forgot the password?

A. There are two important passwords. One is the UIPassword, which protects access to the Cisco ATA Web Server interface; the other is the EncryptKey, which protects access to the TFTP configuration file. If you forget the value for the UIPassword but still have access to TFTP-stored configuration file, you can modify the UIPassword via TFTP. However, if you are not configuring the Cisco ATA via TFTP, or if you forget both passwords, the only way you can recover the box is to have physical access to the box and do a factory reset on the box via the box voice configuration menu interface (Access Code:

FACTRESET#).

Q. What is the maximum distance from which I can drive an analog device with a Cisco ATA?

A. Table 9-1provides maximum distances for this question.

Table 9-1 Ring Loads and Distances

Ring Load (per RJ-11 FXS Port)	Maximum Distance
5 REN	200 feet (61 m)
4 REN	1000 feet (305 m)
3 REN	1700 feet (518 m)
2 REN	2500 feet (762 m)
1 REN	3200 feet (975 m)

The Cisco ATA, however, is not designed for long distance. The simple test is to determine if the phone or phones that are connected to the Cisco ATA work properly in their environment.

Pay attention to the following questions:

1.Can the Cisco ATA detect on/off hook from the analog phone?

2.Can the Cisco ATA detect the DTMF signal?

3.Can you dial the remote side?

4.Can the Cisco ATA ring the phone?
