Table 20-1 Settings on the Collect Logs Tab 

Setting	Description
Enable Logging	To enable the system to collect debug level log data, click Enable Logging. After you click this button, it grays out and the Disable Logging button becomes enabled. You can now attempt to reproduce your system issue. Tip Turning on logging may impact system performance, so enable logging only when necessary. After you finish collecting log data, remember to disable logging by clicking Disable Logging.
Disable Logging	When you have reproduced the system issue, click Disable Logging to stop the system from collecting log data. After you click this button, it grays out and the Enable Logging button becomes enabled.
Generate Log File	To prepare a log file, click Generate Log File. Tip You can generate a log file without enabling/disabling the logging functionality by clicking Generate Log File at any time and downloading the current log collection file. The system displays the progress of the log file generation. When the log file is complete, a link displays that you can click to download the file to your PC. The link contains the time and date that the log file was created. Tip Be sure to download the file to a location on your PC that contains enough disk space to accommodate the size of the log file.

Gateway Loopback

Table 20-2 describes the settings under the Gateway Loopback tab. Your service provider uses loopback test to diagnose connection problems in the network and may ask you to put your T1/E1 interfaces (ports) into loopback mode. You can use the settings under the Gateway Loopback tab to enable or disable loopback mode for the internal gateway ports.

---

Caution Do not add, update, or delete any of the internal gateway ports when you put a port in loopback mode. Adding, updating, or deleting a port can reset the internal gateway and will pull the port out of loopback mode.

---

---

Note You can use the Gateway Loopback tab to initiate loopback for internal gateway only. It is not applicable for external gateways.

Table 20-2 Settings on the Gateway Loopback tab 

Setting	Description
Port	Displays all the internal PSTN gateway ports.
Connection Name	Displays the name of the gateway to which the port belongs.
Description	Provides a brief description of the port.
Status	Displays the status of the port, that is, up, down or unregistered.
Enable Loopback	To put a port in loopback mode, click Enable Loopback. After you click this option, you can either Disable Loopback or Cancel. After you put a port in loopback mode, the gateway to which that port belongs is unregistered. You can verify this through the Health Summary page. Tip You cannot enable loopback if the gateway for that port is not configured.
Disable Loopback	When your service provider completes the testing and asks you to disable loopback, click Disable Loopback to recover the port from loopback. After you click this option, it changes to Enable Loopback.
