Chapter 9 Troubleshooting Frequently Asked Questions • txPktCnt-the total number of RTP packets transmitted • txOctet-the total number of RTP payload octets transmitted Using the refresh feature on the RTP Statistics page, you can obtain updated, real-time RTP statistics during a call. Resetting Cisco ATA counters To reset the Cisco ATA counters, do the following: • Click the [Refresh] link to refresh the current counter values. • Click the [Line 0] link to reset line 0 counter values. • Click the [Line 1] link to reset line 1 counter values. Note Inactive lines will be indicated as such. Frequently Asked Questions Q. Does the Cisco ATA support power denial when disconnecting a call? A. No. However, the Cisco ATA can be configured to reverse the voltage polarity when a call is connected or disconnected. See the "Polarity" section on page 5-39. 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#). See the "Resetting the Cisco ATA to Factory Default Values" section on page 3-23. Q. What is the maximum distance from which I can drive an analog device with a Cisco ATA? A. Table 9-6 provides maximum distances for this question. Table 9-6 Ring Loads and Distances Ring Load (per RJ-11 FXS Port) 5 REN 4 REN 3 REN 2 REN 1 REN Maximum Distance 200 feet (61 m) 1000 feet (305 m) 1700 feet (518 m) 2500 feet (762 m) 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.
