Controller and DS3 Redundancy

Protection Modes

The Axxius 800 can be provisioned with one or two DS3 Controller cards and connections to one or two DS3 lines, which will provide the following levels of protection:

λElectronics Protection – when provisioned with two Controller cards and only one DS3 line, only the Controller cards can be protected

λNetwork Protection – when provisioned with one Controller and two independent DS3 lines, only the DS3 lines can be protected.

λElectronics and Network Protection – when provisioned with two Controller cards and two independent DS3 lines, both the controller cards and the DS3 lines can be protected

Electronics Protection Mode

In this mode there are two DS3 Controllers installed the Axxius 800, but only one DS3 line connected.

The electronics mode of protection provides Controller card redundancy. Because there is only one DS3 connected, there is no DS3 redundancy. The receive path from the DS3 line is simultaneously applied to the receiver of both Controller cards (see Figure). This enables both controllers to monitor the condition of the DS3 line so both are continuously framed up to the incoming signal. The Controller-select signal disables the outputs of the low-speed receive paths on the standby Controller and enables the low-speed receive paths on the active controller. The active Controller’s transmit signal is connected to the transmit path of the DS3 line through a relay, while the standby is disconnected until a protection switch occurs.

The automatic redundancy mode is used to enable and disable protection switching. If the redundancy control process determines the active controller is malfunctioning, or a maintenance switch is invoked (the switch command), a protection switch will occur. This means that the active Controller relinquishes control to the secondary Controller. This is done by enabling the standby Controller’s receive path and disabling the originally active Controller’s low-speed receive path (Controller-select signal) and

Axxius 800 specifications

The Carrier Access Axxius 800 is a versatile telecommunications platform designed to optimize and manage voice and data networks. Initially launched as a solution for service providers, the Axxius 800 has garnered attention for its array of features, extensive connectivity options, and overall flexibility. Leveraging both traditional and modern telecommunications technologies, this device stands out in an increasingly competitive market.

One of the main features of the Axxius 800 is its support for various voice and data protocols, including T1, E1, and DS3 interfaces. This multi-protocol compatibility allows service providers to integrate legacy systems with newer technologies, providing a seamless migration path for businesses looking to upgrade their communications infrastructure. The device supports voice over IP (VoIP) as well, making it an ideal solution for organizations transitioning to IP-based communication systems.

The Axxius 800 is equipped with multiple slots for modular interface cards, allowing operators to customize the system according to their specific needs. This modular approach not only enhances scalability but also ensures that the system can adapt to changing business requirements over time. Users can easily add or remove interfaces, ensuring that they only invest in the capabilities they require.

In terms of management and monitoring, the Axxius 800 features an intuitive web-based interface that simplifies the administration of voice and data resources. This centralized management capability enables easy configuration, monitoring, and troubleshooting, dramatically reducing operational inefficiencies. Additionally, it supports SNMP (Simple Network Management Protocol), allowing for integration with existing network management systems and enabling proactive monitoring of network health.

The Axxius 800 also excels in redundancy and reliability. With dual power supplies and hot-swappable components, the device ensures minimal downtime, which is crucial for businesses that rely on constant communication availability. Security features are another focal point, as the platform offers various encryption and authentication options to safeguard sensitive data.

In conclusion, the Carrier Access Axxius 800 is a robust telecommunications solution that combines flexibility, reliability, and advanced features. Its ability to accommodate numerous technologies, alongside an emphasis on easy management and reliability, makes it an excellent choice for service providers and enterprises looking to enhance their network infrastructure while safeguarding future investments.
