Library means an organized collection of resources made accessible to the public for reference or borrowing supported with money derived from taxation.
Keyboard access Can users access all functions and content, and complete all tasks, independently by using only the keyboard (<tab>, <enter>, <spacebar>, <esc>, and arrow keys)? Verify in particular: o There are no keyboard traps that would prevent a user from advancing through the entire page, such as an automatically-refreshing social media embedded feed (tip: try to tab very, very slowly through any such feed to observe whether a user can close it, or move past it, at a reasonable point; if the feed keeps refreshing by automatically adding additional entries to be shown, it causes a trap for those who are unable to use quick keyboard strokes – or a mouse - to navigate);
online interface means any software, including a website, part of a website or an application, that is operated by or on behalf of an economic operator, and which serves to give end users access to the economic operator's products;
Open type traction battery means a type of battery requiring filling with liquid and generating hydrogen gas that is released to the atmosphere.
Digital Cross Connect System or "DCS" is a function which provides automated Cross Connection of Digital Signal Level 0 (DS0) or higher transmission bit rate digital channels within physical interface facilities. Types of DCS include but are not limited to DCS 1/0s, DCS 3/1s, and DCS 3/3s, where the nomenclature 1/0 denotes interfaces typically at the DS1 rate or greater with Cross Connection typically at the DS0 rate. This same nomenclature, at the appropriate rate substitution, extends to the other types of DCS specifically cited as 3/1 and 3/3. Types of DCS that cross connect Synchronous Transport Signal level 1 (STS-1 s) or other Synchronous Optical Network (SONET) signals (e.g., STS-3) are also DCS, although not denoted by this same type of nomenclature. DCS may provide the functionality of more than one of the aforementioned DCS types (e.g., DCS 3/3/1 which combines functionality of DCS 3/3 and DCS 3/1). For such DCS, the requirements will be, at least, the aggregation of requirements on the "component" DCS. In locations where automated Cross Connection capability does not exist, DCS will be defined as the combination of the functionality provided by a Digital Signal Cross Connect (DSX) or Light Guide Cross Connect (LGX) patch panels and D4 channel banks or other DS0 and above multiplexing equipment used to provide the function of a manual Cross Connection. Interconnection is between a DSX or LGX to a Switch, another Cross Connection, or other service platform device.
