3Com 3C892 manual Firmware IP address, Kbps Layer

Firmware is the code which resides in the ISDN Modem and controls its behavior. It differs from software in the form of programs that run on your computer.

An IP address is a set of numbers that uniquely identifies each device in a network.

Integrated Services Digital Network. ISDN provides a digital telephone service which allows both data and voice communication over the same telephone line and at significantly faster speeds than the traditional POTs service. There are two types of lines which provide access to ISDN, BRI and PRI.

Internet Service Provider. A business that supplies access to the Internet such as your telephone company or AOL.

Kilobits per second. Kbps is the rate at which data is transmitted between communication equipment such as ISDN modems.

In ISDN communications, the physical layer of communication between the communications equipment. If layer one is down, there is no ISDN connection between the devices.

Microsoft’s proprietary version of CHAP. See also CHAP.

Multilink Point-to-Point Protocol. Multilink PPP is a protocol which provides a method for combining multiple PPP connections. With a BRI line, Multilink PPP aggregates the two 56 Kbps or 64 Kbps ISDN B channels, creating a virtual single digital connection of 112 Kbps or 128 Kbps.

An ISDN standard that enables consistency in ISDN service features across different vendors’ equipment and switches for North America.

NetBIOS filtering is a LAN Modem feature that helps prevent the LAN Modem from establishing unwanted calls by filtering the DNS requests made by NetBIOS that inadvertently cause the LAN Modem to place a call. NetBIOS is a protocol primarily used by Windows 98, 95 and NT for local file and printer sharing.

A network termination device that terminates the ISDN line.An NT1 is built into the ISDN LAN Modem with the U interface. An NT1 is built into the ISDN LAN Modem with the U interface (3C892).

Password Authentication Protocol. PAP is one of two PPP authentication protocols supported by the ISDN LAN Modem; CHAP is the other. An authentication protocol requests information to verify a valid user. PAP requests the user’s name and password for verification.

PC/TCP is a PC version of TCP/IP created by FTP software. Plain old telephone service.

PPPPoint-to-Point Protocol. PPP provides a standard method of transmitting data through the Internet. PPP is used for communication between a computer and an Internet service provider.

PPTP Point-to-Point Tunneling Protocol. A protocol that allows a workstation to establish a secure multi-protocol connection to a remote, private network via a locally-dialed ISP account. See also VPN.
