1. Overview

1.1 Product Introduction

The OpenVox DGW-L301 gateway is an E1/T1 digital VoIP gateway that allows digital PSTN and ISDN hubs to connect to VoIP networks. It is a converged media gateway product. This gateway enables seamless integration between traditional telephone systems and IP networks, achieving seamless integration between VoIP PBX and ISDN. With its user-friendly GUI, users can easily configure their custom gateways. Additionally, secondary development can be performed via AMI (Asterisk Management Interface). The DGW-L301 T1/E1 gateway supports 1/2/4 software-selectable T1/E1/PRI interfaces and can handle up to 120 concurrent calls.

Figure 7-9-2 Log Support Interface

Syslog is commonly referred to as system logs or system records and is a standard used to transmit log messages over a TCP/IP network. This term is often used to refer to the actual syslog protocol or the applications or databases that send syslog messages. The syslog protocol is a master-slave protocol: the syslog sender transmits a small text message (less than 1024 bytes) to the syslog receiver. The receiver is typically named

“syslogd,” “syslog daemon,” or syslog server. System log messages can be transmitted using the UDP protocol and/or the TCP protocol.

Syslog Level Overview:

• EMERG: Failure

• ALERT: Warning

• CRIT: Requires immediate attention

• ERROR: Error conditions that prevent the tool or certain subsystem components from functioning properly

• WARNING: Warning information

• NOTICE: Important general conditions

• INFO: Information

• DEBUG: Additional information not related to function conditions or issues
