ADSL Annex M

ADSL Annex M Summary

ADSL Annex M business broadband from Spitfire is designed for companies that require a higher upstream bandwidth compared to ADSL 2+. ADSL Annex M changes the profile of the circuit reducing the downstream slightly in order to provide up to double the upstream compared to ADSL 2+. ADSL Annex M is rate adaptive and so will provide the best possible speed that your telephone line will support up to a maximum downstream of 16Mb and upstream of 2.5Mb.

ADSL Annex M broadband is a cost effective Internet circuit allowing you to download and send data effectively within a range of applications giving you both reliability and business grade performance.

For companies needing to send time critical data, such as voice over IP, the Premium option provides a minimum data throughput of 1Mb as well as guarantees on latency, jitter and packet loss. This option is available from just £69 per month.

ADSL Annex M is best suited for higher volume business and time critical Internet usage. Where symmetrical or even higher bandwidth is required then Ethernet over copper or fibre may be more suitable – see our Ethernet information here.

ADSL Annex M - Where is it available?

ADSL Annex M is now available at most exchanges around the UK where one of Spitfire’s LLU partners has installed the necessary equipment in the exchange. BT are also currently trialling Annex M on their BT 21CN next generation network and on completion Spitfire will also offer Annex M using 21CN equipment.

Assured Data Throughput – Perfect for Real Time Applications

For real time applications, where there is a minimum bandwidth requirement, ADSL Annex M may now be ordered with a minimum data throughput of 1Mb and guarantees on latency, jitter and packet loss, subject to location and distance from exchange.
