The Sangoma A101E is a PCIe network card for use in ISDN and T1/E1 networks. It serves as an AFT card (Analog Front End) and enables the connection of a single T1 or E1 data stream, including fractional T1/E1, to a computer or server. The card is designed for operation in systems based on Primary Rate Interface (PRI) or E1 technology, and is typically used in telephone systems, call center systems, or network management platforms where a stable, dedicated data connection is required.

Applications

The Sangoma A101E is designed for use in professional communication infrastructures, particularly in environments relying on ISDN-based connections. It is commonly used in telephone systems that communicate with the public telephone network via PRI or E1 connections. It can also be used in systems based on T1 or E1 networks, such as in industrial communication or security monitoring systems. Support for fractional T1/E1 allows flexible use, where not the full bandwidth of a T1 or E1 channel is required.

Features and Specifications in Detail

The card enables processing of a single T1 or E1 data stream. T1 connections typically operate at a data rate of 1.544 Mbit/s, while E1 connections have a data rate of 2.048 Mbit/s. Support for fractional T1/E1 means only a portion of the total bandwidth can be used, which is more cost-effective for lower data transmission requirements. The card is designed as a PCIe module, allowing direct installation into a corresponding PCI-Express slot in a server or computer. The AFT function (Analog Front End) refers to the ability to convert analog signals into digital data streams, enabling integration into digital network architectures.

Technology Explained Simply

The Sangoma A101E operates using Primary Rate Interface (PRI) technology, used in telecommunications for transmitting voice and data channels over digital lines. In PRI, a line is divided into multiple B-channels (for voice or data) and one D-channel (for control and signaling). The card enables processing of such a PRI or E1 stream, with the exact number of B-channels depending on the specific configuration. Support for fractional T1/E1 means not all channels of a T1 or E1 stream need to be used, enabling cost-efficient bandwidth utilization. The PCIe interface ensures stable and fast data transfer between the card and the host system.

Compatibility and Accessories

The card is designed for use in systems equipped with a PCI-Express slot. It is compatible with T1 and E1 networks and can be used in environments utilizing PRI or E1 connections.

Installation and Mounting

Installation is performed by inserting the card into a free PCI-Express slot in the computer or server. No additional adapters or external power supplies are required, as the card is powered through the PCIe interface. Configuration of the card is done via software provided by Sangoma or the respective system vendor.

Operational Advantages

The Sangoma A101E provides a reliable and stable connection to ISDN and T1/E1 networks. Support for fractional T1/E1 allows flexible bandwidth usage, enabling cost savings when full capacity is not needed. The PCIe interface ensures fast and reliable data transfer. The card is designed for professional environments where high availability and reliability of communication links are required.
