PPP provides session setup, user authentication (login), and encapsulation for
upper layer protocols such as IP (Internet Protocol). The use of PPP makes the
modem appear as a dial-up modem to the operating system and Dial-Up
Networking is used to establish a connection.
•Bridged Ethernet over ATM (RFC 1483B) / Routed IP over ATM (RFC 1483R).
This protocol makes the modem appear as a LAN (Local Area Network) device to
the operating system.
•Classical IP over ATM (RFC 1577)
This is another LAN alike protocol for IP address and ATM address mapping.
•PPP (Point to Point Protocol) over Ethernet (RFC 2516)
This protocol, commonly called PPPoE, allows multiple computer users on an
Ethernet to share a common ADSL connection to the Internet.
For the HM121dp/di there are two types of device drivers available: WAN and LAN
which both support the ATM protocol.
•WAN driver
This driver causes the modem to resemble a dial-up modem. Call establishment is
performed through Dial-Up Networking. This driver supports PPP over ATM
(RFC 2364) with PVC connections. PPP over Ethernet (RFC 2516) is embedded
into this driver.
•LAN driver
This driver makes the modem appear as a LAN or Ethernet device. The
connection establishment is automatic. This driver supports Bridged Ethernet over
ATM (RFC 1483B) and Routed IP over ATM (RFC 1483R) with PVC
connections. Classical IP over ATM (RFC 1577) is also supported by this driver.
PPPoE is supported via third party software when implemented with a LAN
driver. After installing the LAN driver, follow the installation instructions
provided with the third party PPPoE software. The third party software will search
for existing drivers and Internet connection will be made through the third party
software. You will be required to enter your User name and Password.
