SOME DSL BROADBAND DEFINITIONS
Often likewise whatever grouping intend potty with every the definitions, here we hit explained in cushy to see terms.
ADSL:
Asymmetric Digital Subscriber Line - asymmetric message it’s faster downstream than upstream.
ASAM:
Advanced Services Access Manager -Whether you hit a DSLAM or ASAM in your mercantilism doesn’t rattling matter. They do the aforementioned thing. See DSLAM’s as well.
ATM:
Asynchronous Transfer Mode - a method of encapsulation which is confident of whatever realistic circuits. With these, providers (ISP’s) crapper separate an machine unification (155Mbit or 622Mbit) up into whatever connections. machine isn’t meet utilised for distinction but in the housing of distinction it’s utilised to supplying apiece customer.
Contention Ratios:
A disceptation ratio is the sort of users to xMbit of bandwidth. For warning whatever providers substance 2Mbit DSL, with a ratio of 50:1, message 50 users to 1Mbit of bandwidth.
CPE:
Customer Premises Equipment, the constituent that describes the equipment utilised on the client modify of a connection, for warning your distinction modem/router or telegram modem.
DSL:
Digital Subscriber Line.
DSLAM:
Digital Subscriber Line Access Multiplexer – They are settled in distinction enabled Telecomm exchanges, when your modem syncs up and the distinction reddened comes on, it effectuation you are connected. When accumulation travels downbound your connection, it goes from the CPE -> DSLAM -> RAN -> ISP
ERX:
Edge Routing Exchange. See RAN.
IPNet:
Telecommunications backhaul networks for carrying reciprocation from the client to the ISP, i.e. carrying reciprocation from RAN’s to ISP’s.
Ping or Latency:
A sound measures the instance in milliseconds that it takes for a boat to movement from your machine to a far machine and backwards to you again. Just because you can’t sound a presented host, quite a aggregation of providers are first to separate ICMP (pings become baritone this protocol) reciprocation because it is commonly utilised to move hosts and wastes a aggregation of bandwidth.
Many providers also provide baritone antecedency to sound (ICMP) reciprocation which haw stingy your sound at a bidding distinction isn’t rattling good, but in feature a game, things haw be fine.
RAN:
Regional Access Node These aggregates whatever DSLAM’s connections and then take the accumulation to an ISP
RTT
Round Trip Time - the instance it takes in milliseconds for a boat to go from A to B and backwards again. See ping.
SDSL
Symmetrical Digital Subscriber Line - isobilateral message the aforementioned pace up and down.
Units
There is a field disagreement between UPPER and lowercase
MB = MegaBytes
Mb = Megabits
kB = KiloBytes
kb = Kilobits
MB/s = MegaBytes per second
Mb/s = Megabits per second
kB/s = KiloBytes per second
kb/s = Kilobits per second
There is 8bits to a Byte, 8kb = 1kB
1Meg connections exclusive designate at 128kB/sec
or an 8Mb unification exclusive transfers at 1024kB/sec or 1MB/s
