Windows 98, 2000, Me, and XPADSL Standards and ProtocolsSupports Multi-mode for auto detection of ADSL
protocol
This mode allows the modem to negotiate the correct
modulation against the ISP(s) and Telco(s) equipment. There are four industry-supported
modulations T1.413, G.DMT, G.Lite and CAP. This modem supports all but the CAP modulation. The CAP has been replaced by the
defacto standard G.DMT which is supported. Supports T1.413 issue 2
This is an ANSI standard which defines
the requirements for the single asymmetric digital subscriber line (ADSL) for
the interface between the telecommunications network and the customer
installation in terms of their interaction and electrical characteristics Supports DMT Full-Rate ADSL: up to 8 Mbps downstream,up to 1 Mbps upstream (G.992.1 and T1.413, Issue 2) This is an International
Telecommunications Union’s (ITU’s) recommendation for the single asymmetric
digital subscriber line (ADSL) for the interface between the
telecommunications network and the customer installation in terms of their
interaction and electrical characteristics Supports G.Lite ADSL: up to 1.5 Mbps downstream,up to 512 Kbps upstream (G.992.2) This is an International
Telecommunications Union’s (ITU’s) recommendation which allows for high-speed
"always on" digital communications over a standard copper phone
line at lower speeds than the G.DMT recommendation. The decrease in speed allows the technology to share the
local loop without the need for a splitter at the entry point. Supports DSL handshaking (G.994.1) A Method for DSL systems to negotiate mutually supported
operating modes WAN Service Protocols
RFC 2516 PPP over Ethernet (PPPoE) PPPoE stands for point-to-point protocol over Ethernet. It
is a method of encapsulating your data for transmission over a bridged
Ethernet topology. RFC 2364 PPP over ATM (PPPoA) PPPoA stands for point-to-point protocol over ATM, also known
as point-to-point protocol over AAL5. It is a method of encapsulating your data for transmission
over an Asynchronous Transfer Mode (ATM) interface. RFC 1483 Multi-protocol over ATM (proceeded by RFC 2684) RFC 1483 is an Internet standard for carrying
connectionless routed and bridged Protocol Data Units (PDUs) over an ATM
network. |
