What is the distance limit for providing a satisfactory ADSL service?
c) 3.39 miles or 5.46 kilometers For customers to receive satisfactory ADSL service, the local loop, or distance from the central office, must be less than 5.46 kilometers. What is the approximate distance limitation for providing a satisfactory ADSL service from the central office to a customer?
What is the approximate distance limitation for municipal Wi-Fi?
Municipal Wi-Fi is a variant of the 802.11 standard. 2. What is the approximate distance limitation for providing a satisfactory ADSL service from the central office to a customer? For customers to receive satisfactory ADSL service, the local loop, or distance from the central office, must be less than 5.46 kilometers.
Is ADSL2+ still worth it?
For distances between 3 km and 3.5 km, where ADSL speeds have fallen well below 10Mbps, ADSL2+ and ADSL2 still provide worthwhile increases in connection speeds.
How fast is ADSL2 and ADSL?
Updated February 2021. While ISPs often advertise ADSL2+ and ADSL services as having maximum downlink connection speeds of 24 Mbps and 8 Mbps, respectively, very few broadband users can expect to achieve such speeds.

How much throughput is DSL?
The table does not represent all available rates. In theory, the maximum throughput potential of any first-generation ADSL technology is 8.448 Mbps. However, that would require a subscriber to be very close (within a few hundred feet) to the local CO.
Is throughput capacity proportional to subscriber distance?
Throughput capacity and subscriber distance from the CO are inversely proportional in nature. As distance increases, maximum upstream and downstream speeds decrease. Additionally, other impairments or conditions may contribute to reduced functionality. These include the following:

How fast is ADSL2+?
Updated February 2021. While ISPs often advertise ADSL2+ and ADSL services as having maximum downlink connection speeds of 24 Mbps and 8 Mbps, respectively, very few broadband users can expect to achieve such speeds. As shown in the figure below, a broadband signal generally has to travel considerable distances along the copper cable from the exchange to the street cabinet (the so-called ‘E-side’), and then along another cable from the street cabinet to the nearby residential and business premises (the so-called ‘D-side’).
What happens to broadband signal from exchange?
The broadband signal from the exchange suffers attenuation (loss) as it travels along the cable from the exchange to your broadband modem, reducing the speeds that can be delivered .
4. What is the function of the DSLAM in a broadband DSL network?
communicates directly with customer cable modems to provide Internet services to customers
6. What are two WAN connection enhancements that are achieved by implementing PPPoE? (Choose two.)
Encapsulating Ethernet frames within PPP frames is an efficient use of bandwidth.
15. What functionality does mGRE provide to the DMVPN technology?
It allows the creation of dynamically allocated tunnels through a permanent tunnel source at the hub and dynamically allocated tunnel destinations at the spokes.*
16. Which two scenarios are examples of remote access VPNs? (Choose two.)
A toy manufacturer has a permanent VPN connection to one of its parts suppliers.
A tunnel was implemented between routers R1 and R2. Which two conclusions can be drawn from the R1 command output? (Choose two.)
This tunnel mode is not the default tunnel interface mode for Cisco IOS software.
How much bandwidth does VDSL have?
VDSL boasts a much higher bandwidth capacity than ADSL or SDSL, with a common downstream limit of 52 Mbps and a limit of 12 Mbps for upstream traffic.
What is asymmetric DSL?
Asymmetric DSL (ADSL) is popular Internet-access solution for residential locations. Note that ADSL enables an existing analog telephone to share the same line used for data for simultaneous transmission of voice and data. The maximum distance from a DSL modem to a DSL access multiplexer (DSLAM) is 18,000 feet. This limitation stems from a procedure that telephone companies have used for decades to change the impedance of telephone lines. A DSLAM acts as an aggregation point for multiple connections, and it connects via an ATM network back to a service provider’s router. The service provider authenticates user credentials, obtained via PPPoE, using an authentication server. Also, the service provider has a DHCP server to distribute IP address information to end-user devices (for example, a PC or a wireless router connected to a DSL modem). The term asymmetric in asymmetric DSL implies that the upstream and downstream speeds can be different. Typically, downstream speeds are greater than upstream speeds in an ADSL connection. The theoretical maximum downstream speed for an ADSL connection is 8 Mbps, and the maximum upstream speed is 1.544 Mbps (the speed of a T1 circuit).
What is a DSL phone?
Commonplace in many residential and small-business locations (also known as small office/home office or SOHO locations), digital subscriber line (DSL) is a group of technologies that provide high-speed data transmission over existing telephone wiring. DSL has several variants, which differ in data rates and distance limitations.
Is SDSL the same as ADSL?
Another distinction between ADSL and SDSL is that SDSL does not allow simultaneous voice and data on the same phone line. Therefore, SDSL is less popular in residential installations because an additional phone line is required for data. Also, SDSL connections are usually limited to a maximum distance of 12,000 feet between a DSL modem and its DSLAM.
