Administration of the Avaya G350 Media Gateway - Avaya Support

Chapter 8:Configuring the G350 for modem useYou can connect either a USB or a serial modem to the Avaya G350 Media Gateway. A USBmodem must be connected to the USB port on the G350 chassis. A serial modem must beconnected to the console port (CONSOLE) on the G350 chassis.Both the USB port and the CONSOLE port require configuration for modem use. You canconfigure the ports for modem use via the Avaya IW (see Configuring the G350 using the AvayaIW on page 389) or the GIW (see Configuring the G350 using the GIW on page 427). Fordetails on using a modem with the G350, see Installation and Upgrades for the Avaya G350Media Gateway, 03-300394.This chapter explains how to use the CLI to configure the console and USB ports for modemuse.Configuring the USB port for modem useBy default, the USB port is not enabled. To enable the USB port, you must enable the USBinterface. Use the interface usb-modem command to enable the USB interface. Use the noform of this command to disable the USB interface. The no form of the interface usb-modemcommand also resets the interface to its default parameter values. These values are:●Interface status — down● IP address — 10.3.0.3● Netmask — 255.255.255.0●PPP timeout — None● PPP speed — 38,400 bpsTo set the USB port’s parameters, use the following commands in USB interface context:● Use the async reset-modem command to reset the connected modem. You can usethis command from within an active PPP session over the USB modem.●●Use the speed command to set the PPP baud rate to be used by the USB port whenconnected to a modem (in bits per second). Options are 9600, 19200, and 38400.Use the ip address command to assign an IP address and mask to the USB port. Thisis the IP address to which a remote user can connect using telnet. For example, to assignthe IP address 192.168.22.33 with mask 255.255.255.0 to the USB port, use the followingcommand:G350-001(if:USB)# ip address 192.168.22.33 255.255.255.0The default IP address of the USB port is 10.3.0.3 with the mask 255.255.255.0.Issue 3 January 2005 77
