Ultra-fast premium services and the broadest reach, symmetry and coverage

Subscribers demand content on-demand with transparency to network capacity as to how many bytes a video requires or how big a picture file is. The subscriber’s target is to get the content they want, when they want it. This means the data services that can be offered over existing copper cable plant need to accommodate residential and business as well as being well equipped for educational and government high-speed applications.

Tellabs enables high-speed Internet services for residential, business, educational and government applications with a variety of rates, reaches and symmetry to ensure that subscribers’ needs are met. ITU standards-based ADSL2+ and VDSL2 offer high bit rates for premium services and the broadest reach, symmetry and coverage available. The Tellabs Broadband offering provides the capacity required for the service needs of both today and the future. The Tellabs products are designed to support small-to-large deployments, from the Central Office and remote outdoor sites.

Flexible delivery of ADSL2+ and VDSL2 services

 

Tellabs Broadband enables high-speed Internet services for residential, business, educational and government applications with a variety of rates, reaches and symmetry to ensure that subscribers’ needs are met. ITU standards-based ADSL2+ and VDSL2 offer high bit rates for premium services and the broadest reach, symmetry and coverage available.

 

ADSL2+ solutions

 

Tellabs ADSL2+ (Asymmetric Digital Subscriber Line) products support ADSL2+ with integrated POTS or standalone ADSL2+ for overlay applications. The products support ITU-T 992.1, 992.2, 992.3 and 992.5 with Annex L (Reach Extended) and Annex M (increased upstream). The ADSL2+ provides bit rates up to 24 Mbps on a single pair and up to 48 Mbps when bonding pairs. The Tellabs 1000 MSAP can be deployed in a variety of environments, including locations that best suit the requirements of data services over DSL. A single system can consist of a single terminal in a central office that serves customers directly, or it can have up to 32 subtended remotes with installations in remote cabinets, basements, equipment closets or CEVs.

 

ADSL2+ 6+6 and 6+0 cards

 

The Tellabs 1000 MSAP ADSL products offer six-port modules with options to have the six ports be ADSL only or have each of the six ports support ADSL and POTS on a single copper pair using frequency division multiplexing (i.e., POTS occupies lower frequencies, ADSL higher frequencies and a guard band in between), per international standards. The ADSL product with integrated POTS is the ADSL2+ 6+6B card. The “6+6” indicates that each of the six ports supports ADSL (6) + POTS (6). The ADSL2+ 6+6B card enables network operators to deploy ADSL with POTS and provide high-speed Internet services in locations using the same amount of space required to service POTS only. With integrated ADSL and POTS in a single product, there is no need to spend additional capital and incur added expense to install new cabinets or adjunct cabinets. All services can be provided in the same space required for voice services. Subscribers who have alternate sources for voice services may only want Internet service over landlines; this scenario is also supported by the Tellabs 1000 MSAP. With the ADSL2+ 6+0, six ports of ADSL2+ are provided without POTS. When transmitted over a single copper pair, ADSL2+ can provide up to 24 Mbps.

 

ADSL2+ bonding and business services

 

When two-pair bonding is used, the network can provide up to 48 Mbps, which can support a household with three to four HD video streams while at the same time providing sufficient capacity to stream music, download files and browse the internet. Tellabs 1000 MSAP ADSL2+ also provides attractive capacities for business services. The Tellabs 1000 MSAP ADSL includes the ITU-T Annex M, which provides for extended upstream bandwidth. Instead of the standard 1 Mbps that ADSL supports, Annex M provides up to 3 Mbps in the upstream direction. All of these capabilities are available on the Tellabs 1000 MSAP and are activated simply by provisioning the mode that best fits the requirements.

VDSL2 solutions

 

Tellabs VDSL2 (Very High Speed Digital Subscriber Line) products support ITU-T G.993.2 VDSL2 simultaneously with POTS on a single copper pair. The product supports profiles 8a and 17a for wide deployment opportunities and access speeds provided up to 100 Mbps. The Tellabs 1000 MSAP VDSL2 6+ offers a single solution plug-in for high-speed network access. The VDSL2 6+6B provides deployment and application flexibility. When teamed up with Tellabs 1000 Gigabit Ethernet, it can deliver the highest DSL rates available. It supports standard analog POTS integrated on every pair. Two different VDSL2 profiles can be deployed with simple provisioning options.

 

VDSL2 8a and 17a profiles

 

The 8a profile is best for fiber-to-the-node (FTTN) applications. Bit rates are up to 50 Mbps and provide reaches suitable for FTTN topologies while supporting triple play services. If a network operator wants to increase reach or speed, the VDSL2 6+6B supports 2-pair bonding that doubles the bit rates up to 100 Mbps. The second profile is 17a. The 17a uses 17 MHz of bandwidth at much higher frequencies. It can support very high rates, up to 100 Mbps downstream and up to 40 Mbps upstream over a single pair. With the higher frequencies, transmission distance is best for fiber-to-the-curb (FTTC) and fiber-to-the-building/basement/equipment closet (FTTB).

 

VDSL2 and ADSL2+

 

If reach is critical, the VDSL2 6+6B card can also be provisioned for ADSL2+. Flexibility of deployment environments, a broad range of capacity for all services and the capability to reach all customers make the Tellabs 1000 VDSL2 6+6B card an ideal choice for using a single product type to support all customers and environments. High-speed access to the Internet drives demand for residential and business services. Tellabs Broadband products provide support for xDSL to flexibly provision voice and data services in the way that best meets the needs of our customers.
