3886-6530 Flash RAM Card. A PCMCIA memory card that is only available from the HP
NonStop Server division. While the same software can be used for a DECserver and
AWAN 3886, the AWAN 6530, and Gateway Access Protocol (GAP) features are only
enabled when a 3886-6530 Flash RAM card is installed during power-on or reboot.
The 3886-6530 Flash RAM cards contain a special AWAN 3886 key that is preserved
when a new version of software is field-upgraded. See DECserver and Gateway
Access Protocol (GAP).
asynchronous. A type of serial data transmission supported by a communications port of a
personal computer when using a modem.
AUI. An attachment unit interface (AUI) on the DEChub ONE; it is used to connect the
attached module to a standard Ethernet backbone. An interface used on the AWAN
3886-32 (DECserver 900TM).
BOOTP. A protocol that enables the AWAN server or 3886 AWAN unit (DECserver) to
obtain an Internet Protocol (IP) address.
broadcast. A method of sending information addressed to two or more receiving devices.
Challenge Handshake Authentication Protocol (CHAP). A protocol that is used to verify
a user's identity using a three-way handshake with a challenge and a response. CHAP
issues a challenge to a user attempting to connect to the network. The user then sends
a response. Both the challenge and the response are encrypted, then the encryptions
are compared.
Current Loop. An alternative to RS-232 that is supported by some terminals and serial
printers.
DHCP (Dynamic Host Configuration Protocol. A TCP/IP protocol that enables a diskless
workstation, such as a RAS device, to obtain temporary Internet Protocol (IP)
addresses.
DB-9. A 9-pin connector used for personal computer (PC) communication (COM) ports. See
DB-25.
DB-25. A 25-pin connector that is often used for EIA-232; also called a D-Subminiature
connector because of the shroud, or hood, around the pins is shaped like a “D”.
DECserver. A terminal server without the AWAN 3886-6530 Flash RAM card that only
supports standard terminal server and remote access server functions, such as point-
to-point protocol. The server is manufactured by Digital (DEC), Cabletron, and
currently DNPG (Digital Network Products Group). See gateway.
