When starting a new work at home business it is very easy to become consumed by it. We spend so much time trying to get the business up and running that we may end up becoming burned out and lose our motivation. There is so much to learn and Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable{mso-style-name:"Table Normal";mso-tstyle-rowband-size:0;mso-tstyle-colband-size:0;mso-style-noshow:yes;mso-style-parent:"";mso-padding-alt:0in
ADSL:Asymmetric Digital Subscriber Line - asymmetric meaning it's faster downstream than upstream.ASAM:Advanced Services Access Manager -Whether you have a DSLAM or ASAM in your exchange doesn't really matter. They do the same thing. See DSLAM's as well.ATM:Asynchronous Transfer Mode - a method of encapsulation which is capable of many virtual circuits. With these, providers (ISP's) can split an ATM connection (155Mbit or 622Mbit) up into many connections. ATM isn't just used for DSL but in the case of DSL it's used to provision each customer.Contention RatiosA contention ratio is the number of users to xMbit of bandwidth. For example some providers offer 2Mbit DSL, with a ratio of 50:1, meaning 50 users to 1Mbit of bandwidth.CPECustomer Premises Equipment, the term that describes the equipment used on the customer end of a connection, for example your DSL modem/router, cable modem, black box on Wired Country etc.DSLDigital Subscriber Line.DSLAMDigital Subscriber Line Access Multiplexer - They are placed in DSL enabled Telecomm exchanges, when your modem syncs up and the DSL light comes on, it means you are connected. When data travels down your connection, it goes from the CPE -> DSLAM -> RAN -> ISP ERXEdge Routing Exchange. See RAN.IPNetTelecommunications backhaul networks for carrying traffic from the customer to the ISP, i.e. carrying traffic from RAN's to ISP's.Ping or LatencyA ping measures the time in milliseconds that it takes for a packet to travel from your computer to a remote computer and back to you again. Just because you can't ping a given host, quite a lot of providers are beginning to filter ICMP (pings come under this protocol) traffic because it is commonly used to attack hosts and wastes a lot of bandwidth.Many providers also give low priority to ping (ICMP) traffic which may mean your ping at a command line isn't very good, but in say a game, things may be fine.RANRegional Access Node These aggregates many DSLAM's connections and then feed the data to an ISPRTTRound Trip Time - the time it takes in milliseconds for a packet to go from A to B and back again. See ping.SDSLSymmetrical Digital Subscriber Line - symmetrical meaning the same speed up and down.
