Using the Bantam Jacks for Test Port Functionality

Using the Bantam Jacks for Test Port Functionality

Test port functionality is supported by Cisco IOS Release 12.1(2)XD and later releases.

Monitoring Mode for the T1, E1 and T3 DFCs

The monitor mode is available on the T1, E1 and T3 dial feature cards.

If a T1 controller does not come up, or there is a large number of errors associated with a particular controller, you might be able to determine whether the problem is in the DFC or in an external T1 line by using the test port. The test port is a set of bantam jack connectors located on the front panel of the T1, E1, and T3 DFCs. (See Figure 6-7.)

In monitor mode, you can monitor only the ingress side of the T1 line without disrupting that line.

The bantam jack connectors located on the front panel of the DFCs allow the connection of an external test device (for example, a FIREBERD test device) to monitor the individual T1 circuit in monitor mode. Use software commands to select a T1 line. For information on software commands, see the

Cisco AS5350 and Cisco AS5400 Universal Gateway Software Configuration Guide for details.

Passive monitoring equipment is used to listen on the TX MON and RX MON jacks during regular operation to detect T1 errors.

Connecting test equipment to the following bantam jack connectors provides various functions:

•TX MON can monitor signals coming out of the test port without interrupting normal data transmission.

•RX MON can monitor signals going in to the test port without interrupting normal data transmission.

Drop and Insert Mode for the CT3 DFC

Drop and Insert mode is available on the T3 DFC.

The bantam jack connectors located on the front panel of the T3 DFC allow the connection of an external test device (for example, a FIREBERD test device) to test any of the 28 individual T1 circuits in drop-insert mode.

In drop-insert mode, the T1 line is dropped out of service. To prevent accidental use of the push button in drop-insert mode, use the test trunk drop-insertprivileged EXEC command to disable the drop-insert mode on the specified T3 controller.

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.
