The widely deployed Cisco series modular access routers are designed to enable customers to easily adopt future technologies and scale to accommodate network expansion. The Cisco series shares modular interfaces with the Cisco , Cisco , and Cisco series, providing a solution to meet the today branch office needs for applications such as the following:. The Cisco series modular architecture provides the versatility needed to adapt to changes in network technology as new services and applications become available.
Driven by a powerful RISC processor, the Cisco series supports the advanced quality of service QoS , security, and network integration features required in evolving enterprise networks of today. Cisco IOS Release For detailed descriptions of the new hardware features, see the "New and Changed Information" section. Cisco , Cisco , Cisco , Cisco 3.
For general information about upgrading to a new software release, refer to S oftware Installation and Upgrade Procedures located at the following URL:. The latest firmware version 1. Additional information can be found on Cisco.
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
Note If you have a Cisco. The following sections list the new hardware and software features supported by the Cisco series for Release Before the call admission control feature, gateways did not have a mechanism to gracefully prevent calls from entering when certain resources were not available to process the call.
This causes the new call to fail with unreported behavior, and could potentially cause the calls that are in progress to have quality related problems. This feature set provides the ability to support resource-based call admission control processes. These resources include system resources such as CPU, memory, and call volume, and interface resources such as call volume. If system resources are not available to admit the call, two kinds of actions are provided: system denial which busyouts all of T1 or E1 or per call denial which disconnects, hairpins, or plays a message or tone.
If the interface-based resource is not available to admit the call, the call is dropped from the session protocol such as H. This feature allows a user to configure call admission thresholds for local resources as well as memory and CPU resources. The list of local resources that are configured for call admission are described in the command description of "call threshold poll-interval".
With the call admission command, a user is allowed to configure two thresholds, high and low, for each resource. Call treatment is triggered when the current value of a resource goes beyond the configured high. The call treatment remains in effect until current resource value falls below the configured low.
Having high and low thresholds prevents call admission flapping and provides hysteresis in call admission decision making. With the call spike command, a user is allowed to configure the limit for incoming calls during a specified time period. My config is below. I think the current version is TN Emulation software.

An error can occur with management protocol processing. Please use the following URL for further information:. Problem is occurring when the customer is attempting to receive dial-tone on ISDN trunks.
The method that the customer uses to obtain this dial-tone is to configure the ISDN trunks for overlap-receiving, and send in a setup message with no called party number.
This causes the dial-tone from the router to not be heard. Symptoms: Performance for the encrypt path degrades when using this image with the hardware encryption card.
The performance loss is due to encrypted packets being process instead of fastswitched. When dialplan pattern is configured for the local IP Phones, the existing call-forward commands under ephone-dn are not entered under the E. This can cause a call not getting forwarded if you dial the entire E number. This problem happens only if you add or edit the existing dialplan pattern with call-forward commands already in place.
One way to avoid this problem is to configure the right dialplan pattern before configuring the call-forward commands. Additionally, if you modify the dialplan pattern commands, configure the call forward commands again under ephone-dn. This creates the call-forward commands under the E dial-peers created. Music on hold works inconsistently in certain conditions.
A calls B and conferences to C. B puts the conference on hold. B resumes the call and after a while puts the conference on hold again. Now only A initiator hears the MOH. If the WAN link comes back up during the call and the call is between two IP phones or two analog phones, the call is not dropped. However, if the call is between an IP phone and an analog phone, the call is dropped. The following sections describe the documentation available for the Cisco series.
These documents consist of hardware and software installation guides, Cisco IOS configuration guides and command references, system error messages, feature modules, and other documents. Documentation is available as printed manuals or electronic documents, except for feature modules, which are available online on Cisco. These documents are available for the Cisco series on Cisco. A feature module consists of a brief overview of the feature, benefits, configuration tasks, and a command reference.
As updates, the feature modules are available online only. Feature module information is incorporated in the next printing of the Cisco IOS documentation set. Each module in the Cisco IOS documentation set consists of one or more configuration guides and one or more corresponding command references.
Chapters in a configuration guide describe protocols, configuration tasks, and Cisco IOS software functionality, and contain comprehensive configuration examples. Chapters in a command reference provide complete command syntax information. Use each configuration guide with its corresponding command reference.
These electronic documents may contain updates and modifications made after the hard-copy documents were printed. The following sections provide sources for obtaining documentation from Cisco Systems.
