What is VDSL DSLAM?

What is VDSL DSLAM?

VDSL- Very High Bit-Rate Digital Subscriber Line (VDSL) VDSL can achieve downstream rates of 55 Mbps and upstream rates of 1.5-2.3 Mbps. VDSL2 can achieve downstream rates of 200 Mbps and upstream rates of 200 Mbps up in the first 1,000ft. While VDSL is considered asymmetric, VDSL is both symmetric and asymmetric.

What is the difference between DSLAM and Msan?

Typical outdoor MSAN cabinet consists of NarrowBand (POTS), BroadBand (xDSL) services, batteries with rectifiers, optical transmission unit and copper distribution frame. [DSLAM] A Digital Subscriber Line Access Multiplexer (DSLAM) allows telephone lines to make faster connections to the Internet.

What is a DSLAM port?

A digital subscriber line access multiplexer (DSLAM, often pronounced DEE-slam) is a network device, often located in telephone exchanges, that connects multiple customer digital subscriber line (DSL) interfaces to a high-speed digital communications channel using multiplexing techniques.

Which types of signal is used by VDSL?

A VDSL connection uses up to seven frequency bands, so one can allocate the data rate between upstream and downstream differently depending on the service offering and spectrum regulations. The first-generation VDSL standard specified both quadrature amplitude modulation (QAM) and discrete multi-tone modulation (DMT).

Does VDSL require a landline?

While SDSL also requires a separate line from your phone, it uses only a single line instead of the two used by HDSL. Very high bit-rate DSL (VDSL) – An extremely fast connection, VDSL is asymmetric, but only works over a short distance using standard copper phone wiring.

What is a NBN DSLAM?

Fibre to the Building (FTTB): Fibre runs to a multi-unit building into an nbn™ co-installed device called a DSLAM. From there, service is delivered to customers over existing copper wires. FTTC connects a distribution unit, usually housed in a pit in the ground, with the existing copper network via fibre.

How much space does the ADSL2+ IP DSLAM take?

The ADSL2+ IP DSLAM occupies only 1.5U of standard Telco rack space. It will easily fit in existing remote terminals. Each ADSL2+ IP DSLAM unit from Versa Technology is equipped with a fan and air filter unit. The unit features low power requirements plus full diagnostic and alarm reporting capability.

What are the DSLAM features?

The DSLAM features SNMP, CLI and Web GUI based powerful, easy-to-use features including remote access and software downloads that help service providers minimize daily operational costs.

What is the vx-1000hdx mini-DSLAM?

The VX-1000HDX ADSL2+ IP DSLAM unit from Versa Technology features 48 ports. This gives users the ability to generate additional revenue with minimum installation time and expense. The mini-DSLAM offers flexibility to service providers to deliver various services by offering a wide range of multiple DSL connectivity speeds at different prices.

What is the difference between VDSL2 and ADSL2+?

Our VDSL2 DSLAMS and ADSL2+ DSLAMS deliver triple play services over existing copper plants.VDSL2 allows for symmetrical speeds of up to 100Mb and offers longer distances than standard VDSL technology using the same upstream frequencies. Our VDSL2 and ADSL2+ units help network administrators create dependable and profitable broadband networks.
