AddPac Technology Proprietary & Documentation 93 - 83
75Ω cable for analog signal process and high speed digital signal process.
CODEC
An acronym for COder-DECoder 1. Built-in circuit device for coding/decoding
of analog signal to bit stream with Pulse Code Modulation method. 2. DSP
software algorithm for compressing/ decompressing voice or audio signal
Console
DTE interface whether the command is delivered to the host.
CoS
Class of Service (CoS) is a way of managing traffic in a network by grouping
similar types of traffic (for example, e-mail, streaming video, voice, large
document file transfer) together and treating each type as a class with its own
level of service priority. Unlike Quality of Service (QoS) traffic management,
Class of Service technologies do not guarantee a level of service in terms of
bandwidth and delivery time; they offer a "best-effort."
Decryption
The process of converting encrypted data back into its original form, so it can
be understood.
DHCP
Dynamic Host Configuration Protocol. A protocol which allows a host to obtain
configuration information, such as its IP address and the default router from a
server. This simplifies network administration because the software keeps
track of IP addresses. With DHCP device can have a different IP address
every time it connects to the network
DNS
Domain Name Server, an Internet service that translates domain names into
IP addresses.
DS-3
Digital signal level 3, A line capable of delivering 44.7 Mbps (44,700 Kbps) in
both directions
DSP
Digital Signal Processor. Dedicated microprocessor for digital signal process.
DTMF
Dual Tone Multi-Frequency. Using two types of voice-band tones for dialing.
E&M
An acronym for recEive and transmit or ear and mouth. E&M interface uses
a RJ-48 telephone cable to connect remote calls from an IP network to PBX
trunk lines (tie lines) for local distribution. It is a signaling technique for two-
wire and four-wire telephone and trunk interfaces.
E1
The basic building block for European multi-megabit data rates, with a
bandwidth of 2.048Mbps.
Encryption
the manipulation of a packet's data in order to prevent any but the intended
recipient from reading that data.
Ethernet
Broadband LAN standard initiated by Xerox Corporation and co-developed by
Intel and DEC. Utilizing CSMA/CD and the various cables of 10Mbps are
used. It is similar to IEEE 802.3. Refer to: 10Base-2, 10Base5, 10Base-F,
10Base-T, 10Broad-36, Fast Ethernet, IEEE 802.3.
FAX
Short for "FACSimile." In essence, a fax machine sends an electronic
"facsimile" or copy of the document. An optical scanner in the machine scans
