DS3 Controller Card

Controller and DS3 Redundancy

Network Protection Mode

The network mode of protection requires a single Controller with two independent DS3 channels. The cross connects are set up identically for both DS3s. Both revertive and non-revertive modes are applicable. Two DS3 framers are present on the DS3 Controller card. Both are framed to their respective incoming data. Backplane data is sent to both transmitters and is sent out both interfaces. On loss of signal or high bit error rate, software will switch from Primary to Secondary interface. In revertive mode, if the signal returns to the Primary interface or the BERT level is restored for a period of time, software will return control to the Primary interface. In non-revertive mode, return to the Primary interface would be by command only or if the secondary line fails and the primary has returned to normal operation.

Electronics and Network Protection Mode

The highest level of protection, electronics and network protection, allows both the Controller cards and the DS3 lines to be switched. This mode is available with two Controllers and two active DS3 lines. Network protection switching must be enabled and cross connects set up. In this mode, the primary Controller is connected to the both the primary DS3 line and the secondary DS3 lines (TX and RX). The low-speed transmit streams are multiplexed, framed and simultaneously broadcast on both the primary and secondary DS3 lines, thus transmitting the identical payload to the far-end service and protection line. Also, each Controller is framed up to both its DS3 lines and the Controller select signal determines which Controller has access to the low- speed cards, and thus carries the service.

If the active Controller malfunctions, if the DS3 line condition deteriorates, or a maintenance switch is invoked (the switch command), a protection switch will occur in the Axxius DS3, which enables the secondary DS3 path through the other Controller card. If revertive switching is enabled after a five minute delay (beginning when the previously-active controller’s error rate equals zero) the Axxius DS3 will switch back to the previously-active Controller and DS3 line, if there is no longer a malfunction in that path during the five-minute delay. If revertive switching is not enabled no switch- back will occur.

NOTE: After a switching event in revertive mode, switching cannot occur again until the original Controller and DS3 line have experienced 5 minutes of error-free operation. The 5-minute delay is built-in, and conforms to standards to prevent oscillation during poor DS3 line conditions.

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.
