To verify your D channel configuration:

Enter the show interface serial command and make sure that the line protocol is up and that you are using the correct IP interface. Also, make sure that excessive errors are not being reported.

Configuring the Universal Port Dial Feature Card and Lines

Rather than the more traditional line/modem one-to-one correspondence, lines are mapped to a service process element (SPE) that resides on the universal port DFC. Associated SPE firmware serves a function similar to modem code on a MICA modem.

One SPE provides services for six ports, with additional ports per SPE. Busyout and shutdown can be configured at the SPE or port level.

The universal port DFC performs the following functions:

Converts pulse code modulation (PCM) bitstreams to digital packet data.

Forwards converted and packetized data to the main processor, which examines the data and forwards it to the backhaul egress interface.

Supports all modem standards (such as V.34 and V.42bis) and features, including dial-in and dial-out.

Note For detailed information about the universal port DFC CLI commands, refer to Monitoring Voice and Fax Services on the Cisco AS5350 and Cisco AS5400 Universal Gateway, available online at the following URL:

Cisco AS5400, Cisco AS5350 specifications

Cisco Systems is a global leader in networking and telecommunications technology, and its AS5350 and AS5400 models are prominent offerings in their product line. These devices cater primarily to service providers and large enterprises looking for advanced VoIP, data, and multimedia capabilities.

The Cisco AS5350 is a versatile voice gateway that supports a wide range of protocols including VoIP and PSTN (Public Switched Telephone Network). Designed for scalability, it can handle numerous simultaneous calls, making it an ideal solution for businesses that require robust communication systems. Some of its main features include built-in support for various signaling protocols such as SIP (Session Initiation Protocol) and H.323, which allow seamless integration with existing networks. Additionally, the AS5350 is equipped with high-density digital signal processors (DSPs) that enable efficient call processing and transcoding, ensuring high-quality voice transmission.

On the other hand, the Cisco AS5400 takes this functionality a step further by offering enhanced capabilities suited for more demanding environments. It supports both voice and data services, allowing service providers to deliver a comprehensive solution that includes voice calls, multimedia applications, and broadband services. The AS5400 features a modular design, allowing users to adapt the device to specific needs by adding or removing modules as required. This modularity enhances flexibility and future-proofs the system against evolving technology demands.

Both the AS5350 and AS5400 incorporate advanced security features to protect sensitive communications and data. Features such as encryption, secure signaling, and network access controls are essential for enterprises looking to safeguard their operations in an increasingly vulnerable digital landscape. These gateways also support Quality of Service (QoS) protocols, ensuring that voice traffic is prioritized over other types of data, thereby maintaining call clarity even in times of high data demand.

In conclusion, the Cisco AS5350 and AS5400 are compelling solutions that showcase Cisco's commitment to delivering reliable and high-performance telecommunications devices. By offering state-of-the-art technology, robust features, and a modular approach to scalability, businesses and service providers can ensure they remain competitive in the ever-evolving telecommunications landscape. Whether it is for voice, data, or multimedia applications, these gateways deliver the performance and flexibility needed to meet current and future challenges.
