The general trademark of a manufacturer by which the consumer knows its products. A manufacturer can have multiple brand names. Some manufacturers license their brand names to other producers.
Product name:
Product name is a brand's identification of a product, often a model name, but not totally unique as it can include some product variants. Product name is a key part of the Icecat product title on a product data-sheet.
Article code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product code if the specifications are identical. We map away wrong codes or sometimes logistic variants.
EAN/UPC code :
European Article Number (EAN) and Universal Product Code (UPC) are better known as the barcode on a product's packaging to uniquely identify a product in a shop or logistic process. One product can have multiple barcodes depending on logistic variations such as packaging or country.
Category :
With a router you can connect networks. Most people will use a router to connect their local (wireless) home or office network (LAN) with the Internet. The router makes sure that all computers on the local network can connect with one another, with shared resources and with the Internet and can be configured to forward requests for connections from computers on the internet to the appropriate local computer. In order to connect your local network to the internet via an ADSL or cable, you also need an (Ethernet) ADSL or cable modem if it is not built-in in the router, which is most likely to be the case.

Better utilization of bandwidth
The IES-1248 is an IP-based DSLAM that terminates all the ATM circuits and converts traffic directly to deliver the most popular broadband IP services. It also provides a distinct advantage over typical ATM-based DSL access system due to the fact that IP is the natural approach for data transmission. It offers better bandwidth utilization, ease of use, as well as the low-cost advantage. With the highly compact and temperature-hardened design, simple installation and easy adaptation to local POTS/ISDN splitter requirements, the IES-1248 can be deployed in indoor and outdoor enclosures.

A robust, capable ADSL2+ solution
With this standalone ADSL2+ IP DSLAM, service providers can offer residential and business users access to high-bandwidth services on demand; such as streaming video, online gaming, multimedia applications and multiple video channels on a single network connection. The IES-1248 also offers medium/small businesses and home offices IP connectivity, VPNs, VLANs, high-quality video conferencing, long-reach Ethernet and legacy service interconnection, as well as asymmetric connectivity as fast as 24Mbps. The IES-1248 DSL solution for POTS/ISDN is a sophisticated ADSL2+ device wielding full compliance to existing standards, the latest DSL technology, compactness, low power consumption, integration with existing platforms and network managemeability. The combination of a superior line code, modern signal processing techniques and state-of-the-art ASIC design add up to a compact, energy-saving ADSL2+ modem with excellent performance, transparent backward ADSL/ADSL2 compatibility, robust interference resistance and flexible configurabilit

A digital subscriber line (DSL) connection is a connection of a computer or router to a telephone line which provides the digital subscriber line service, for connectivity to the Internet.Types of connections include USB and RJ45 (for Ethernet).
DSL specification
G.992.3, G. 992.5

DHCP server*
A server is a system which that responds to requests across a computer network to provide, or help to provide, a network service. DCHP servers uses the DCHP (Dynamic Host Configuration Protocol), which is a standardized networking protocol used by servers on an IP network to allocate IP addresses to computers. The purpose of DHCP is to automate the IP address configuration of a computer without a network administrator. IP addresses are typically selected from a range of assigned IP addresses stored in a database on the server and issued to a computer which requests a new IP address. An IP address is assigned to a computer for a set interval, after which, the computer must renew the IP address or acquire a new one.
DHCP client*
Supported network protocols
Network protocols tested as compatible with this product e.g. FTP,HTML, POP.
MAC address filtering
Security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists.
