Mixing WAN DFCs

The Cisco AS5350 and Cisco AS5400 support only one type of WAN DFC at a time. The DFCs that can be installed at one time are:

Up to three T1 DFCs (any combination of 2, 4, or 8-port) or

Up to three E1 DFCs (any combination of 2, 4, or 8-port) or

One CT3 DFC or

One CT3 DFC and up to two T1 DFCs (any combination of 2, 4, or 8-port)

The universal gateway software recognizes DFCs in the order of the slots they are in. For example, a DFC in slot 2 will be recognized before a DFC in slot 3. The system will recognize if there is a mix of WAN DFCs during both power up and OIR:

During power up, the first WAN DFC recognized by the system will be the only type brought up.

If there are two or more WAN DFCs of the same type and one is hot-swapped with another of a different type, the new one will not be recognized.

In both situations, an error message will appear on the console that is similar to:

00:01:12:%CARRIER-2-T1_E1_MIX:Cannot mix T1 and E1 8PRI DFC cards in chassis, do not power up invalid card in slot 7

AS5350, AS5400 specifications

Cisco Systems has long been a leader in the networking and telecommunications field, and its AS5800 series of routers exemplify this tradition. The AS5800, along with the AS5850, AS5350, AS5400, and AS5300, provides robust solutions for service providers and enterprise-level networking applications. Each of these models has distinct features and characteristics that cater to the evolving demands of internet traffic and data processing.

The Cisco AS5800 is designed for high-capacity routing and optimized for broadband services. It supports a wide range of services, including voice, data, and video applications, making it a versatile option for service providers looking to deliver integrated solutions. It is equipped with advanced quality of service (QoS) features that ensure bandwidth is allocated effectively, holding strong even under heavy traffic conditions.

In comparison, the AS5850 offers superior processing capabilities and is typically utilized in larger-scale implementations. This model supports high-density interfaces, allowing numerous connections without compromising performance. Its architecture includes enhanced MPLS (Multiprotocol Label Switching) support, enabling more efficient traffic management and better utilization of network resources.

The AS5350 is known for its scalability and energy efficiency, ideal for voice-over-IP (VoIP) and media gateway applications. It supports various telephony features, such as protocol interworking and transcoding, making it a preferred choice for organizations focusing on digital voice technologies. The AS5300, while slightly older, continues to be a valuable asset for less demanding networks, offering reliable performance with VoIP capabilities and basic data applications.

The AS5400 bridges the gap between high-performance routing and operational efficiency. It incorporates Cisco's proprietary technologies to ensure seamless connectivity and robust failover systems. This model is highly regarded for its security features, protecting network integrity and providing peace of mind for businesses relying on sensitive data transfer.

Overall, Cisco’s AS5800 series showcases a progressive evolution of routing capabilities with enhanced features tailored for resilience, scalability, and performance. These routers not only address the technical needs of modern networks but also strategically position organizations for future growth in an increasingly digital world. Each model, with its unique attributes, continues to support the varied demands of global communication infrastructures.
