hop count

A routing metric used to measure the distance between a source and a desti- nation. Particularly used by RIP.

hub

(1)Communications center, (2) Major routing station for connecting channels,

(3)DDS connecting center.

IEEE

Institute of Electrical and Electronic Engineers. Professional organization that defines network standards. IEEE LAN standards are the predominant LAN standards today and include protocols similar or virtually equivalent to Ether- net and Token Ring.

IEEE 802.1d

An algorithm used to prevent bridging loops by creating a spanning tree.

IEEE 802.2

An IEEE LAN protocol that specifies an implementation of the LLC sublayer of the data link layer. It handles errors, framing, flow control, network layer (Layer 3) service interface, and is used in LANs.

IEEE 802.3

A physical layer standard specifying a linear bus network LAN with a CSMA/ CD access method on a bus topology. Ethernet follows the 802.3 standard, transmitting at 10 megabits per second. This is the most common local area network specification. Physical variations of IEEE 802.3 include 10Base2 and 10BaseT.

in-band signalling

Signalling made up of tones which pass within the voice frequency band and are carried along the same circuit as the talk path being established by the sig- nals. Virtually all signalling (request for service, dialing, disconnect, etc.) in the U.S. is in-band signalling. Most of that signalling is MF (Multi-Frequency) dialing. The more modern form of signalling is out-of-band.

interexchange carrier

Since divestiture, any carrier registered with the FCC authorized to carry cus- tomer transmissions between LATAs interstate, or if approved by a state pub- lic utility commission, intrastate. Includes carriers such as AT&T Communications, Satellite Business Systems, GTE Telenet, GTE Sprint, and MCI.

information element

The name for the data fields within an ISDN Layer 3 message.

Express XLT, Express XL specifications

ADTRAN has established itself as a leading provider of telecommunications solutions, and among its impressive lineup, the ADTRAN Express XL and Express XLT stand out as robust offerings designed for the evolving demands of modern networks. These devices cater to service providers and enterprises looking to enhance their broadband delivery capabilities while ensuring cost-efficiency and reliability.

The ADTRAN Express XL is a high-capacity, next-generation fiber optic access platform. It is engineered to support a wide array of technologies, including Passive Optical Network (PON) standards such as GPON and XGSPON. The Express XL's architecture allows for seamless scalability, making it a perfect fit for both small-scale deployments and expansive network rollouts. What sets it apart is its ability to deliver ultra-fast broadband services to residential, business, and mobile backhaul customers with its impressive throughput capabilities.

On the other hand, the Express XLT builds upon the success of the Express XL by incorporating advanced features aimed at maximizing operational efficiency. It supports technologies including Active Ethernet and offers flexible network configurations to meet specific service requirements. Both models utilize ADTRAN’s innovative Dynamic Bandwidth Allocation technology, which dynamically allocates bandwidth to users based on real-time demand, ensuring optimal performance and user satisfaction.

A key characteristic of both ADTRAN Express XL and XLT is their energy efficiency. Designed to minimize operational costs, these units use power-saving technologies that reduce energy consumption without compromising performance. Furthermore, they include built-in support for network functions virtualization (NFV) and software-defined networking (SDN), providing operators with the agility to adapt their networks in response to changing market conditions.

In addition to their advanced technological underpinnings, the Express XL and XLT boast an intuitive management interface, simplifying network monitoring and management tasks. They also feature comprehensive telemetry and analytics capabilities that help operators gain insights into network performance, optimize configurations, and troubleshoot potential issues before they affect end users.

Ultimately, the ADTRAN Express XL and Express XLT are pivotal components for service providers aiming to deliver high-speed broadband services effectively. With their blend of flexibility, scalability, and energy efficiency, these access platforms are well-positioned to meet the current and future demands of telecommunications networks worldwide.
