Step 6 Return to privileged EXEC mode:

Gateway(config-controller)# Ctrl-Z

Tip To save the gateway configuration, save it to NVRAM. Refer to the “Saving Configuration Changes” section on page 57.

Verify

To verify that your controller is up and running and that no alarms have been reported:

•Enter the show controller command and specify the controller type, slot, and port numbers:

Gateway# show controller t1 1/7

T1 1/7 is up.

No alarms detected.

Framing is ESF, Line Code is B8ZS, Clock Source is Line Primary.

Version info of slot 2: HW: 2, Firmware: 14, NEAT PLD: 13, NR Bus PLD: 19 Data in current interval (476 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs Total Data (last 24 hours)

0 Line Code Violations, 0 Path Code Violations,

0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,

0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

•Note the following:

–The controller must report being up.

–No errors should be reported.

If you are having trouble:

•First decide if the problem is because of the T1 or E1 line or with a particular channel group. If the problem is with a single channel group, you have a potential interface problem. If the problem is with the T1 or E1 line, or with all channel groups, you have a potential controller problem.

•To troubleshoot your E1 or T1 controllers, first check that the configuration is correct. The framing type and line code should match to what the service provider has specified. Then check channel group and PRI-group configurations, especially to verify that the time slots and speeds are what the service provider has specified. At this point, the show controller t1 or show controller e1 commands should be used to check for T1 or E1 errors. Use the command several times to determine if error counters are increasing, or if the line status is continually changing. If this is occurring, you need to work with the service provider.

•Another common reason for failure is the dial-tdm-clock priority setting. The default setting is a free-running clock that causes clock slip problems if not set properly.

Configuring a Channelized T3 DFC

Your CT3 card offers 28 individual T1 channels (bundled in the T3) for serial transmission of voice and data. The CT3 link supports the maintenance data link channel in C-bit parity mode and also payload and network loopbacks. The T1s multiplexed in the CT3 link support facilities data link (FDL) in extended super frame (ESF) framing.

Note The CT3 controller numbering convention is dfc-slot/portin CLI commands. DFC slot numbering starts from the motherboard and works up from left to right. Slot 0 is reserved for the motherboard. The DFC slots are numbered sequentially from 1 to 7. Port number value is always 0. Under the CT3, the CT1 controller numbering convention is dfc-slot/port:channelin CLI commands. Port numbering values range from 1 to 28.

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.
