Introduction

Cisco Systems extends enterprise-class and managed services customer premises equipment (CPE) versatility, integration, and power to branch offices with the Cisco 2600 series modular access router family. The widely deployed Cisco 2600 series modular access routers are designed to enable customers to easily adopt future technologies and scale to accommodate network expansion. The Cisco 2600 series shares modular interfaces with the Cisco 1600, Cisco 1700, and Cisco 3600 series, providing a solution to meet today's branch office needs for applications such as:

•Internet/intranet access with firewall security

•Multiservice voice/data integration

•Analog and digital dial access services

•Virtual Private Network (VPN) access

•Inter-VLAN routing

•Routing with bandwidth management

The Cisco 2600 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 2600 series supports the advanced Quality of Service (QoS), security, and network integration features required in today's evolving enterprise networks.

Feature Set Tables

Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Table 3 lists the Cisco IOS Release12.1(5) YD6 feature set image for the Cisco IAD2420 series platforms.

Cisco IOS Release 12.1(5) YD6 supports the same feature sets as Cisco IOS Release 12.1(5) T, but Cisco IOS Release 12.1(5) YD6 can include new features supported by the Cisco 2600.

---

Caution Cisco IOS images with strong encryption (including, but not limited to, 168-bit Triple Data Encryption Standard [3DES] data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of United States government regulations. When applicable, purchaser and user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 3 lists the new features and feature sets supported by the Cisco 2600 series in Cisco IOS Release 12.1(5) YD6 and use the following conventions:

•Yes—The feature is supported in the software image.

New and Changed Information

The following sections list the new hardware and software features supported by the Cisco 2600 series for Release 12.1(5) YD6.

New Hardware and Software Features from Cisco IOS Release 12.1(5) YD1 to Cisco IOS Release 12.1(5) YD6

There are no new hardware or software features supported by the Cisco 2600 series from Cisco IOS Release 12.1(5) YD1 to Cisco IOS Release 12.1(5) YD6.

New Hardware Features in Cisco IOS Release 12.1(5) YD

There are no new hardware features supported by the Cisco 2600 series for Cisco IOS Release 12.1(5) YD.

New Software Features in Cisco IOS Release 12.1(5) YD

The following new software feature is supported by the Cisco 2600 series for Cisco IOS Release 12.1(5)YD.

IP Keyswitch

The IP Keyswitch feature provides Cisco IP phone call-handling capabilities in a LAN environment. This feature enables the Cisco 2600 series to provide IP Keyswitch capability integrated in the router for the Cisco IP Phone 7960, Cisco IP Phone 7940, and Cisco IP Phone 7910. It loads phone images, and configures, and manages the Cisco IP phones in your LAN. It also provides a host of features such as call forwarding, call transfer, and hold, for example. The IP Keyswitch feature provides you with integrated call processing capabilities for a small office with up to 48 extensions.

Refer to the following documents for further information:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121limit/121yd/121yd_5/ipkeys.htm

Survivable Remote Site Telephony

The Survivable Remote Site Telephony feature provides the Cisco CallManager with fallback support for the Cisco IP phones attached to the router on your local Ethernet. Cisco IOS Release 12.1(5)YD integrates this feature on the Cisco 2600 series and enables the routers to provide call handling support for the Cisco IP phones when the Cisco IP phones lose connection to the remote primary, secondary, or tertiary Cisco CallManager or when the WAN connection is down.

The Cisco CallManager 3.0 supports Cisco IP phones at remote sites attached to Cisco branch office multi-service routers across the WAN. Prior to Survivable Remote Site Telephony, when the WAN connection between the remote branch office router and the Cisco CallManager failed, or connectivity with the Cisco CallManager was lost for some other reason, the Cisco IP phones at the branch office became unusable for the duration of the failure. To overcome this problem the Survivable Remote Site Telephony feature was developed. The feature provides call-handling support on the branch-office router for its attached Cisco IP phones when a failure occurs. The system automatically detects the failure, and using Simple Network Auto Provisioning (SNAP) technology, auto configures the branch office router to provide call processing service for the local IP phones. When the failure is restored, call-handling capabilities for the Cisco IP phones switch back to the primary Cisco CallManager. During a failure, the Cisco IP phone displays a message to inform the user that the Cisco IP phone is in the Cisco CallManager fallback mode and is able to perform a limited set of functions.

Refer to the following documents for further information:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121limit/121yd/121yd_5/fallback.htm

Important Notes

The following sections contain important notes about Cisco IOS Release 12.1(5)YD2 that can apply to the Cisco 2600 series.

Product Number Change

Beginning with Cisco IOS Release 12.0(7)XK, Cisco changed the product numbers used to order a specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train, maintenance release, and build number. The following table provides some examples.

Old Product Number	New Product Number	Release	Image Description
S364AR1K2-12.0.7XK=	S364AR1K2-12007XK=	Cisco IOS Release 12.0(7)XK	Cisco 3640 Series IOS Enterprise/SNA SW PLUS IPSEC 3DES
S26CP-12.1.3=	S26CP-12103=	Cisco IOS Release 12.1(3)	Cisco 2600 Series IOS IP Plus

MIBs

To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules, go to the Cisco MIB website on Cisco.com at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.

Deprecated and Replacement MIBs

Old Cisco MIBs will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBs without affecting existing Cisco IOS products or network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 4.
