Q. What is U-Verse High Speed Internet aka IP-DSLAM HSI?
A. U-Verse HSI is an IP-based DSL product using ADSL2/2+ technology.Q. What the difference between a normal DSLAM and an IP-DSLAM?
A. IP-DSLAM stands for Internet Protocol Digital Subscriber Line Access Multiplexer. IP-DSLAMs deal with mostly IP based traffic rather than converting between the older ATM (Asynchronous Transfer Mode) and IP.Q. What equipment is used?
A. There are currently two different provided equipment to choose from: 1. AT&T Gateway (2Wire 2701HGV-B) 2. Modem ((Motorola 2210-02-1ATT)Q. Must I purchase the equipment or does AT&T own the Gateway/Modem and I am leasing/renting?
A. With U-Verse HSI you are purchasing the equipment. It is yours, this is unlike traditional U-Verse RGs which remain the property of AT&T.Q. Am I charged the "High Speed Internet Equipment Fee", like customers who have stand-alone traditional U-Verse [VDSL] High Speed Internet Service?
A. No, for IP-DSLAM customer, you own the equipment; there is no monthly fee.Q. Will a technician be sent to install the service or can I install the equipment myself?
A. You can choose to have a Professional Tech Installation, there is a charge of $149. If you choose this option keep in mind this is in addition to the cost of the equipment. You can choose to have the equipment sent to your home for a self installation. There are no additional charges for this; you will just pay for the equipmentQ. Is there a warranty of the equipment I purchase?
A. Yes, your equipment either as a self-install or a professional install includes a one  year warranty. This warranty covers the Gateway/Modem, in-line filters, and associated connecting cords.Q. Is there a difference from traditional ADSL service?
A. This new platform is IP-based and is being used used in areas primarily where U-Verse has been deployed. This is not to be confused with U-Verse Internet that is offered with U-Verse TV; U-Verse Internet + U-Verse TV is VDSL service and the signal is from a local VRAD.Q. How do I know whether I am ordering U-Verse HSI or regular U-Verse service [Internet, TV, VoIP]?
A. If you are placing an order online you will be directed to »uverse.att.com and when you put you address you will only be able to order Internet Service; The TV and Voice services will show not available. If you are speaking with an agent on the phone, the sales agent will identify your are qualified for U-Verse Internet only; if you want to double check you can ask the agent if the validation system says "IP-DSLAM ACCOUNT" or if the system identifies the address as "IP-CO".Q. I do not want U-Verse Internet, I want traditional DSL, how can I do this?
A. At this time, in areas where U-Verse has been deployed, the traditional ADSL equipment is being retired. U-Verse HSI over ADSL2/2+ is meant to replace the traditional ADSL offerings; the services are wholly similar with the exception of how the service is provisioned. U-Verse HSI using ADSL2/2+ is very different from traditional U-Verse Internet; traditional U-Verse Internet uses VDSL and has more stringent distance limitations.Q. Is this service from the Central Office [CO], a Remote Terminal [RT], a Video Ready Access Device [VRAD]?
A. U-Verse HSI is currently CO based. If your address qualified for TV, Voice, and internet you are out of a VRAD; thus, you would be a traditional U-Verse customer over VDSL and not an IPDSLAM customer over ADSL2/2+.Q. Are there distance limitations?
A. Yes, ADSL2/2+ does have distance limits; they are similar to those of traditional ADSL setups. IP-DSLAM customers are not restricted to the limits of traditional U-Verse [VDSL] requirements.Q. What speeds are available?
A. The same speeds offered under traditional ADSL are available; the speed you qualify for is based upon your distance. The available speeds are: [Down/Up] 768/384, 1536/384, 3008/512, & 6016/768. These speeds differ from traditional U-Verse [VDSL] services that offer higher download speed tiers and minimum of 1Mbps upstream speeds.Q. Can I combine my U-Verse HSI bills with AT&T Telephone service?
A. No, at this time only AT&T wireless services can be combined with U-Verse HSI. If you have an AT&T landline you will receive 2 separate bills.
