AT-VP504E FXS 27

Basic Configuration

This chapter describes how to configure the AT-VP504E FXS for basic

operation.

Configuring the

Software

The AT-VP504E FXS software parameters are fully programmable

using the SNMP protocol. There are two ways to set up and configure

a unit:

By using a SNMP browser to contact the MIBs of the

AT-VP504E FXS.

This manual explains how to use any third-party SNMP

browser to monitor and configure the AT-VP504E FXS,

provided the correct MIB structure is installed on the

management workstation. You can use any SNMP browser

or network management application running the SNMP

protocol. However, the information may not be presented in

the same manner depending on the SNMP browser used.

Network Management

When managing an AT-VP504E FXS over the network, the unit must be correctly configured with an IP

address and a subnet mask.

IP Addresses

To operate correctly, each unit on a network must have a unique IP address. IP addresses have the

format

n.n.n.n

where

is a decimal number between 0 and 255, for example,

192.168.0.1

. If your

network has a connection to the external IP network, you need to apply for a registered IP address.

This system ensures that each IP address is unique; if you do not have a registered IP address, you

may be using an address identical to someone else’s and your network may not operate correctly.

Subnets and Using a Subnet Mask

You can divide your IP network into sub-networks or subnets. Support for subnets is important because

the number of bits assigned to the device part of an IP address limits the number of devices that may

be addressed on any given network. For example, a Class C address is restricted to 254 devices.

Note: If you have a small network (less than 254 devices), you may decide not to have subnets.

If you are unsure about what mask to use, Allied Telesyn suggests that you use a general mask,

255.255.255.0

, which corresponds to the example address used in the previous sections.

Note: It is assumed that you have basic knowledge of TCP/IP network

administration.
