Objective

To provide information regarding the setup and configuration of a DSL Modem in the Bridge configuration and client computer setup information.

Scope

This procedure will cover the installation of a DSL modem configured for use with a static IP addressing scheme when a router is not envolved. It also includes the necessary steps of configuring the client computer for use with static addressing.

Responsibilities

During the initial installation of the DSL circuit, the service provider will be responsible for the proper installation and configuration of the modem to work under the static addressing. It will be the responsibility of the PTAGIS Field operations personnel to configure the router for use with the client computer's maybe necessary for PTAGIS Field Operations personnel to reconfigure the modem in critical instances where the site is not communicating and no support from the provider is available.

Procedure

DSL Line PreQualification

1. PreQualify telephone line for DSL compatibility. Contact local DSL provider for a circuit test on the phone number of the facility in which the service will be installed.

• Even though the telephone company indicates that the line qualifies for DSL services, problems can arise when the technician comes to the site and starts the installation. At times, internal telephone equipment problems will hinder the install and the installation has to be postponed until the problems are corrected either by the phone company or facility personnel.
• Also keep in mind that the committed information rate or the data speeds will vary given the condition of the line and distance from the central service switch.To ensure that the information rate that was purchased is being fulfilled, ask the technician to run a line test and speed test and present the results for future archiving and reference. This could be of use when troubles arise and the connections speeds are noticeably slow.
• Request that a minimum of 2 static I/P addresses are allocated for the 2 data collection computers. These addresses will be provided to you by the service technician at the time of the installation.
• Also, the service provider will supply you with the Default Gateway addresses along with DNS server information you will need for configuration at the the client level.

DSL Modem Installation

1. Connect a standard RJ-11 connectorized telephone cord to the port on the DSL Modem filter assembly labeled (telco)to telephone wall jack originating from the D-mark punch block.
2. Connect another RJ-11 phone cable from the filter labeled (OUT) to the DSL modem.
3. On the back of the DSL modem, connect an RJ-45 network cable from the network port(LAN) to a network hub.
4. Connect a telephone handset to the jack on the DSL filter labeled(Phone).

DSL Modem Configuration

• Note:As it stands, most PIT-tag data services will be assigned 2 static I/P addresses, one for each of the data collection computers.This allows for a static route to the computers for remote access purpose's utility computer will be standalone with no services if another static I/P is not available.
• Note:Without the use of a network router and or firewall appliance that will accommodate for a VPN tunnel, the above configuration is the only means of remote access into the data collection computers.
• In the above configuration, The modem will need to be configured as a "Bridge". In this configuration, all static information will be configured on the client PC rather dynamically assigned by the external DHCP server.
• Refer to the following link for instructions on DSL Modem Bridging.
• Note: These instructions are specific to the "Zyxel 645" modem which is currently in use at the Prosser facility can be used as a general guideline for other modems but menu items and directories may look different in modems with different firmware versions and or different modem manufacturers.

Client Computer Setup

• It is assumed that the PTAGIS technician is adept to network configurations within various operating systems.

1. On the Primary data collection computer, in the "Network Configurations" TCP/IP settings, Enter the static I/P address for that computer.
2. Then modify the DNS server settings with the primary and secondary DNS information provided by the DSL service provider.
3. Then Modify the Default Gateway information again with the address provided by the DSL service provider.
4. Repeat steps 1 through 3 above for the secondary computer and utility computer respectively.

Test the Installation

Thoroughly test the installation to ensure that the static routes,gateway and DNS entries are configured and working properly. To do this, follow some suggestions below.

1. Try to surf the Internet with a browser. Go to http://www.ptagis.org or another web address. If successful, then the configuration should be ready to transfer data to PTAGIS.
2. If the above is unsuccessful, Try using the PING command to PING the external default gateway address or the DNS addresses. Keep in mind that some gateways do not allow the PING command through their firewall.
3. If the above test is unsuccessful,check the internal network configuration for typo's and try again. If still unsuccessful,then refer to the DSL installer to help isolate the problem.
4. Once you are able to surf the internet, then verify the data upload from the interrogation software using the internal diagnostic tools provided in the software.'SOP PTTP Uploader Site Configuration'
