WAN Indicators

 

LNK

Flashes when the link is being negotiated; solid when the link

 

is active.

B1

Flashes when a call on the B1 channel is in progress; solid

 

when a call is connected.

B2

Flashes when a call on the B2 channel is in progress; solid

 

when a call is connected.

Loop

Indicates ISDN layers status. Indicator is off when layer 1 is

 

down. A fast flash indicates layer 1 is up and layer 2 is down.

 

A slow flash indicates layer 2 is up and layer 3 is down. A sol-

 

id illumination indicates all layers are up.

PWR

Flashes when self-test has failed; solid when unit is powered

 

on and self-test has passed.

Test Indicators

 

ERR

Illuminates when self-test or front panel test has failed.

B1/B2

Indicates test selected by front panel buttons.

Pushbutton Tests

The echo request test can be executed by pressing the SELECT button one time and pressing TEST. A ping test is executed by pressing the SELECT button twice and pressing TEST. The IP address pinged comes from the previously pinged address set in the menu. If it is blank, the default gateway is used. If the default gateway is blank, an error is indicated. The ERR indicator illumi- nates if any pings are not returned. The dial self-test is invoked from the front panel if the SELECT button is pressed three times. The LDN(s) must be al- ready programmed for this test to work.

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.
