The Alcatel 1000 ADSL high speed modem provides high speed virtual
connections to multiple services simultaneously, using ATM/ADSL on standard
telephone twisted pairs.
Asymmetric Digital Subscriber Line (ADSL) is a high speed transmission
technology that takes advantage of existing copper telephone lines and new
telephone technologies to deliver data services to residential and small business
users located within a limited distance from the Central Office (CO) exchange.
Additionally, ADSL operates over standard voice-grade telephone circuits without
disturbing the existing telephone connections. Telephone lifeline service is NOT
impacted by any failure of the modem.
The Alcatel 1000 ADSL high speed modem features industry standard ATM
Forum-25.6 Mb/s (ATMF) or 10BASE-T Ethernet interfaces. Both ATMF-25 and
Ethernet can use the high bit rates available through the ADSL line.
The ATMF-25 interface plugs into a Personal Computer (PC) with an ATM-Forum
(ATMF) 25.6-Mb/s interface.
The 10BASE-T Ethernet interface allows single or multiple PCs to share the high
speed ADSL line.
Figure 15 shows the generic network infrastructure. Residential or small office
ADSL users have access to corporate Local Area Networks (LANs) or Internet
Service Providers (ISPs) or both.
