To qualify for ADSL, much more than distance has to considered, meaning every customer will go through a pre-qualification process. The pre-qualification process involves:

• Customer telephone lines are tested on a regular basis based on criteria including

The distance of the customer’s premises from the telephone exchange. The bandwidth available degrades with the distance travelled.

The ‘condition’ of the telephone line.

The result of these tests are combined to provide an indication of the lines’ capability to carry ADSL services. This indicator is represented by either a ‘PASS’ or a FAIL’ flag, where a ‘PASS’ flag indicates that a line will be capable of getting ADSL, and a ‘FAIL’ flag indicates that a line will not be capable of getting ADSL. The prequalification indicator is then loaded into an industry standard prequalification database which is used by DSL operators to check the status of customers lines as required.

How reliable are the ADSL prequalification results?

The prequalificationification test is a predictive tool and is not an absolute guarantee that the line tested will support ADSL service. Service cannot be proven until the installation on site has been completed. Prequalification has nevertheless proven to give a reliable and accurate indication that lines passing can support service.

ADSL uses higher frequencies than those traditionally used by the PSTN network.

This allows PSTN and ADSL to operate in parallel.

One analogy is the process is blowing a dog whistle, the frequency is outside our hearing range and therefore we can not hear it. ADSL is outside the PSTN frequency range and therefore does not interfere.

ADSL, by definition, is asymmetric - this can be a good fit for access to Internet services, where users typically download more information then they upload.

PPPoE

PPPoE / EnterNet 300

This software is the equivalent of Dial Up Networking for ADSL, it provides username and password authentication allowing users to log on to the ADSL service.

SOLO and MULTI account users will need this installed on each system using the service.

Why PPPoE?

• PPPoE vs PPPoA vs DHCP

• Flexibility of RADIUS– Ease of integration with existing systems– Per-customer IP addressing & QoS– Usage-based billing

• “Preserves the dial-up experience!”


ILUG AGM 22/6/02

Contention

• Wholesale ATM bitstream service– Open to OLOs– Contention ratio of 24:1– i-stream retail service is built on this

• Retail IP service– Dual 100Mb/s & 155Mb/s uplinks from i-

stream to core eircom IP network– No IP level restrictions / contention– 80/20 rule & download allowances
