Support and Installation

RSL Business Broadband 500 is a self-install service i.e. you are free to source the appropriate DSL router/modem and appropriate number of microfilters yourself to support the installation.

The BT engineer will convert the existing BT analogue telephone line to an ADSL line by making changes at the BT exchange. After the line has been converted you will need to do the following: -

Firstly, you will need to attach a suitable microfilter to your BT master socket and any extension sockets connected to it. The microfilter simply plugs in to the socket in place of your existing telephone and has two connectors, one for the telephone and another for your RSL Business Broadband 500 service. Please note that if you do not install microfilters on the master socket and extensions, your RSL Business Broadband 500 service may not operate correctly.

Secondly it will be necessary to connect and configure a suitable ADSL router or modem to the ADSL port on one of the microfilters. If you are using an Ethernet based router, it will be necessary to connect this to your Ethernet network. If you do not already have an Ethernet network, it will be necessary for you to install a suitable Ethernet hub. Note that some Ethernet routers come with built in Ethernet hub. If you are using a PCI card or USB modem, it will be necessary to install the device on your computer. Note that there are some issues of compatibility of various operating systems with some PCI and USB devices. Please check with the manufacturer's details before purchasing/installing. Suitable device drivers are normally shipped on CD-Rom with the modem.

Note: NAT (Network Address Translation) has the benefit of increased security on a network. As implemented, the NAT option prevents users from collecting SMTP mail or running any type of server, and software making use of specific ports may not work. The Non-NAT configuration on Demon ADSL services includes up to 13 usable IP addresses and SMTP mail. If this option is chosen, or is supplied with the service, customers are advised to run a firewall on the network.
