Introduction
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
∙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
∙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.
