BACP Bandwidth Allocation Control Protocol is a dynamic bandwidth allocation technique that enables, if utilisation of the channels already present exceeds a specified threshold value, the connection of additional channels.

BOOTP Boot Protocol. A TCP/IP protocol, which allows an internet node to discover certain start-up information such as its IP address

BRI Basic Rate Interface. An ISDN subscriber “interface”. Consists of 2 bearer B-channels at 64 kilobits per second and a data D-channel at 16 kilobits per second. B-channels designed for voice and D-channel for the data i.e. receiving information about the incoming call and taking out information about outgoing call.

CHAP Challenge-Handshake Authentication Protocol. An authentication scheme used by PPP servers to validate the identity of the originator of a connection, upon or during connection. The server can request the connected party to send a new challenge message at any time. Because CHAP identifiers are changed frequently and because authentication can be requested by the server at any time, CHAP provides more security than PAP.

CLI/CLID Calling Number Identification.

DDI Direct Dialling Inward. A service where a call made to a DDI number arrives direct, without the intervention of an organisation’s operator, at an extension or group of extensions

DHCP Dynamic Host Configuration Protocol. Allows a server to automatically give out IP addresses to workstations. Can also provide subnet mask, default gateway, WINS server and DNS server addresses etc. A DHCP server verifies the device’s identification, “leases” an IP address for a predetermined amount of time and reclaims the address at the end of period for reassignment.

DNS Domain Name System. System used on the Internet to translate Internet domain names (i.e. www.networkalchemy.co.uk) into IP addresses. This means you can use the internet without having to remember IP addresses. Domain Name Service is an Internet utility that implements the Domain Name System. DNS servers maintain databases containing the addresses and are accessed transparently to the user.

DPNSS Digital Private Network Signalling system. A UK standard that enables PBXs from different manufacturers to be tied together with E-1 lines and pass call transparently between them. International version called Q.SIG/Q.931, which is Euro-ISDN.

DTE Data Terminal Equipment. The DTE port on the Argent unit is used as a diagnostic aid.

DTMF Dual Tone Multi-Frequency. Describing push button or Touchtone dialling. When you touch a button on a push button pad, it makes a tone, a combination of two tones - one high frequency and one low frequency. Thus the name Dual Tone Multi Frequency.

Finger An Internet utility, originally limited to UNIX but now available on many other platforms, that enables a user to obtain information on other users who may be at other sites (if those sites permit access by finger). Given an e-mail address, finger returns the user’s full name, and indication of whether or not the user is currently logged on, and any other information the users has chosen to supply as a profile. Given a first or last name, finger returns the logon names of users whose first or last names match.
