Solution Description and Scope
The Cisco Wireline Video/IPTV Solution, Release 1.1, supports both broadcast video and video on demand (VoD) for the wireline market. This enables operators that use digital subscriber lines (DSL) and fiber to offer not only video but also voice over IP (VoIP) and data (Internet access)—collectively referred to as "triple play"— over their existing infrastructure, now intelligently optimized for video service. (The solution assumes that Internet access is already available.)
Generic Architecture and Scope
Figure 1-1 presents a generic view of the Cisco GOVoBB Solution transport architecture. The shaded area shows the scope of solution testing and documentation. The solution uses a Gigabit-Ethernet (GE) transport network consisting of the following:
•
•
•
The regional access network, or RAN, consists of distribution, aggregation, and access layers. There is one SHE per region or network, and one VHE per metropolitan area. A distribution edge router (DER) provides transport for video traffic between the IP/MPLS core network and the VHO. The real-time encoder encodes and compresses analog signals. The VHO, in turn, is connected to the VSOs through one or more ARs. The customer premises equipment consists of residential gateways, or RGs. (RGs are also referred to as home access gateways, or HAGs.)

Out of Scope
Not included in the scope of the solution, but still required to support triple play, are items such as subscriber device authentication for one or more of the other nonvideo services. In addition, the architecture of this release places minimal requirements on the DSLAM. This allows the solution to work with as many third-party DSLAMs as possible.
Solution Components
Cisco Equipment
Release 1.1 consists of core Cisco components that are tested, documented, and fully supported by Cisco. Also, third-party equipment, although not fully supported by Cisco, has been selected and tested in conjunction with the core components, to increase the number of test cases and improve the overall quality of the solution in practical networks. The following Cisco equipment has been tested in the context of the solution:

Miscellaneous Solution Support
This section clarifies the degree to which other aspects of the solution and its implementation are supported in this first release.
Operational Support Systems
Release 1.1 does not certify element management systems (EMSs) or network management systems (NMSs) operated within the context of the Cisco Wireline Video/IPTV Solution architecture. Customers continue to provide such capabilities as applicable to their particular environments. All the management information base (MIB) components for the Cisco equipment are available from Cisco, and can be incorporated into the customer's current EMS.
Billing
Billing is outside the scope of this first release of the solution.
EMC
Release 1.1, with all its platforms, accessories, and components, complies with applicable electromagnetic compliance (EMC) standards.
Safety
Release 1.1, with all its platforms, accessories, and components, complies with applicable safety standards.
