Point-to-Point

: allows one TE (Terminal Equipment) device that may be up to 1 km from the NT

(Network Termination) unit.

Short Passive Bus

: allows connection of up to 8 TE devices in parallel on the S/T bus. Each TE

terminal can be connected at any point of the bus within 100 to 200 meters from the NT unit.

Extended Passive Bus

: allows connection to 8 TE terminals at distances of up to 500 meters from

the NT terminal. All TE devices are situated at the end of the bus, with maximum distance between

them 25 - 50 meters.

An ISDN S-bus must be terminated twice, once at the start and once at the end of the bus, with

100-ohm resistors. In the common case that the NT unit is at one end of the bus, the NT will have 100-ohm

terminators applied, and the farthest TE terminal device will have 100-ohm terminator.

When configured to operate in NT mode, the OxyGEN miniOffice BRI interface emulates the NT unit,

whereas when configured to operate in TE mode, it emulates the TE terminal. In any case, depending

on the bus topology, it frequently must be terminated with 100-ohm resistance. To this end, the OxyGEN

miniOffice has for each BRI interface configurable switches to apply a 100-ohm termination to the

S-Interface signal pairs (

On

position) or not (

Off

position). These switches, depending on the OxyGEN

miniOffice model, are located either below the BRI interfaces or at the bottom of the device.

Glossary

Term

Description

6to4

It is an IPv6 transition technology. This mechanism allows IPv6 sites to communi-

cate with each other over the IPv4 network without explicit tunnel setup. These

sites communicate with native IPv6 domains via relay routers.

Using 6 to 4,

IPv6 hosts do not require IPv4-compatible IPv6 addresses or configured tunnels.

Therefore, IPv6 gains considerable independence of the underlying wide area

network and can step over many hops of IPv4 subnets.

802.1Q

The standard issued by the IEEE defining VLAN tagging in Ethernet networks.

See VLAN.

802.11

A family of specifications for wireless LANs developed by the IEEE. This is an

Ethernet protocol, often called Wi-Fi. The 802.11 family includes many different

modulation techniques that use the same basic protocol, the most popular of

which are 802.11b, 802.11g, 802.11a and the emerging 802.11n.

10BASE-T

A designation for the type of Ethernet networks with a data rate of 10 Mbps.

See Ethernet.

100BASE-T

A designation for the type of Ethernet networks with a data rate of 100 Mbps.

See Ethernet.

ACS Server

Auto-Configuration Server

The ACS is a server responsible for the configuration of the end-user devices in a

broadband network using the TR-069 protocol.

ADSL

Asymmetric Digital Subscriber Line

The most commonly deployed "flavor" of DSL for home users is asymmetrical

DSL. The term asymmetrical refers to its unequal data rates for downloading and

uploading (the download rate is higher than the upload rate). The asymmetrical

rates benefit home users because they typically download much more data

from the Internet than they upload.

ADSL speeds range from 1.5Mbps to

9Mbps downstream (to the subscriber) and from 16Kbps to 800Kbps upstream,

depending on line distance.

ADSL Lite

A lower data rate version of ADSL technology.

ADSL2/ADSL2+

Newer forms of ADSL that add new features and functionality targeted at

improving performance and interoperability. Among the changes are improve-

ments in ADSL’s data rate, an increase in the distance between the DSLAM and

the CPE, dynamic data rate adaptation, better resistance to noise, diagnostics,

and a stand-by mode to save power. ADSL2+ rates range up to a maximum

theoretical download speed of 24 Mbps.

AFTR

Address Family Transition Router element de-encapsulates the packets sent to it

by the CPE and and performs network address translation before sending them

to the public Internet. The NAT in the AFTR uses the IPv6 address of the client

in its NAT mapping table. This means that different clients can use the same

private IPv4 addresses, therefore avoiding the need for allocating private IPv4 IP

addresses to customers or using multiple NATs (see also Dual Stack Lite).

Analog

An analog signal is a signal that has had its frequency modified in some way, such

as by amplifying its strength or varying its frequency, in order to add information

to the signal. The voice component in the traditional telephony (POTS) service is

an analog signal.

See Digital.

Annex A

Annex of the ADSL standards defining xDSL service functioning over POTS lines.

Annex B

Annex of the ADSL standards defining xDSL service functioning over ISDN lines.

Annex L

Annex of the ADSL standards defining xDSL service with increased range of up

to 7 kilometers.

Annex M

Annex of the ADSL standards defining xDSL service with upstream bandwidth

increased from 1 Mbit/s to 2 Mbit/s.

ARP

Address Resolution Protocol.

The protocol used for finding a host’s hardware

address (MAC address) when only its network layer address (IP address) is known.

APN

Access Point Name. The APN determins how the GSM endpoint communicates

via the GSM network to a host site (i.e., how the carrier network passes IP traffic

to the host network). An APN determines what IP addresses are assigned to the

mobile station, what security methods are used, and how the GSM data network

connects to the customer’s network.

Appsocket / Jetdirect

An HP protocol for printing over the network.

Asymmetrical

Offering different data rates in the upstream and downstream directions, where

upstream is the direction from the end-user to the network, and downstream is

the direction from the network to the user.
