C900TTL-X Configuration

D6600 NetCom System Guide

7.9 Identifying the MAC Hardware Address

Note: If you already know the IP address of the C900TTL-X and it has already been configured, skip down to Section

7.12 Verification that the IP Address Assigned is Correct.

Once everything is verified and set up properly per the

previous steps it is time to program in the IP address of the

C900TTL-X. The first step is finding and writing down the

MAC or hardware address of the C900TTL-X. This address

is hard-coded into the C900TTL-X during its manufacture

and cannot be changed. This address is 6 bytes (12 digits)

in length and can be found on a label on the large metal

box soldered to the C900TTL-X.

The MAC or hardware address for the above labeled

C900TTL-X is found on the label here. It is a good idea to

record this number for future reference.

7.10 Obtaining an IP Address

Go to the network administrator with the MAC address. The network administrator will assign your C900TTL-X

an IP Address.

An IP Address is an identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol

route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric

address written as four numbers separated by periods. Each number can be zero to 255. For example,

190.200.128.111 could be an IP address. Within an isolated network, you can assign IP addresses at random as

long as each one is unique. However, connecting a private network to the Internet requires using registered IP

addresses (called Internet addresses) to avoid duplicates.

7.11 Initial Assignment of the IP Address using ARP.EXE

Radionics recommends that you read this entire step before beginning. Also, make sure there is power to the

C900TTL-X and the Ethernet Network RJ45 connection is in place.

The C900TTL-X being configured and the PC being used to configure it must both be on the same

gateway [the device that connects the LAN to the WAN] In order to Telnet [the process of using the

TELNET program to communicate with the C900TTL-X and establish it’s communications

configuration parameters] into the configuration program. The gateway may be called a router, hub,

or MAU. After the C900TTL-X has been configured and it has an IP address - you will be able to

telnet in to change configuration parameters from anywhere on the network.

Once you have the IP address and the network administrator confirms that it is ready, open up the MS-DOS

prompt (from Windows) on any PC tied into the network that is to be used. You will now need to use the ARP

program to assign the C900TTL-X its new IP address. ARP, short for Address Resolution Protocol, is a program

used to convert an IP address into a hardware address such as a MAC. The ARP program is installed into the

C:/WINDOWS directory by default in Microsoft

Windows

95, Windows

98, Windows

2000, and Windows

Millennium Edition during install.

At the MS-DOS

prompt (usually

C:\windows), the following

command syntax is to be used:

arp –s xxx.xxx.xxx.xxx zz-zz-zz-zz-zz-zz

xxx.xxx.xxx.xxx

is the IP address assigned

to the C900TTL-E Dialer

Capture Module by the

Network Administrator

zz-zz-zz-zz-zz-zz

is the MAC hardware address

found on the label of the

C900TTL-E Dialer Capture

Module .

The following steps detail the assignment of an IP address to a

C900TTL-X Dialer Capture Module, using the ARP program. The

EXAMPLE MAC Address is used as an example.
