DSLAM Definition: A DSLAM, or Digital-Subscriber-Line-Access-Multiplexer, is a network distribution device that aggregates individual subscriber lines into a high-capacity uplink. These high capacity uplinks, either ATM or Gigabit Ethernet, connect subscribers to their Internet service providers (ISPs...
When the phone company receives a DSL signal, anADSLmodemwith aPOTSsplitter detects voice calls anddata. Voice calls are sent to thePSTN, and data are sent to the DSLAM, where it passes through the ATM to the Internet, then back through the DSLAM and ADSL modem before returning to the cu...
DSL modems typically plug into a filter that separates voice from data. Here’s a short list of what happens: Step 1: Your provider’s DSL access multiplexer (DSLAM) splits the telephone line’s usable data bandwidth into 247 separate channels, each 4 kHz wide and containing an analog car...
ADSL (Asymmetric Digital Subscriber Line) is a technology that facilitates fast data transmission at a highbandwidthon existing copper wire telephone lines to homes and businesses. Unlike regular dial-up copper telephone line service, ADSL provides continuously available, always-on broadband connections. ...
A DSL modem connects to the phone line and communicates with a DSLAM (Digital Subscriber Line Access Multiplexer) at the service provider’s facility, which aggregates connections and provides access to the broader internet. The quality and speed of a DSL connection can vary based on the distanc...
A cable modem termination system is capable of performing many of the functions of a digital subscriber line access multiplexer (DSLAM) in a DSL system. It has both RF and Ethernet interfaces. A CMTS mostly carries Internet Protocol traffic, and it both transmits and receives digital cable mode...
The closer to the DSLAM the better, as the signal degrades with distance, causing latency issues. If a user is at the outskirts of the service area, he or she might not see the full speed of the subscribed plan. A DSL modem is commonly included with service as a “leased” item to...
The main component at the local end offices is the DSLAM (digital subscriber line access multiplexer) whose main task is to merge the data and the telephony services with the IP video services. Now the main function of the local end office is to combine all this information and distribute it...
is 500 ~ 1000m, and the distance between VDSL2 equipment and the user is within 500m. A large number of Ge services need to be transmitted to the bas and SR of the end office. The combination of OTN or OTN + OCDMA-PON is a better choice, which will greatly save the rapid ...
