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.

Open Caveats—Cisco IOS Release 12.2(2) XK
•CSCdv54780
Problem: Traceback seen when shut/no shut performed on ATM interface (ADSL WIC) after DSL has trained.
Workaround: No workaround known at this time.
•CSCdv48631
When 20 or more permanent virtual circuits (PVCs) are configured AND data is sent such that the pvcs are congested, the router is crashing. However, when the data is sent at less than the line rate, there is no crash. It has been verified that three PVCs, carrying data up to the line rate and with these three PVCs congested, the router is working fine. So, it is not advised to configure more than three pvcs carrying data to a level where each PVC gets congested.
The crash is platform specific and happens only on 2611 with two ethernet ports. And it only happens when data is send on eth0/1.It does not happen on 2610.
Number of PVCs that are supported is currently five VBR-NRT and five UBR with the exception of the problem that is specific to 2611 on data sending to eth0/1. Other platforms are ok with 5/5 PVCs.
•CSCdv45229
AALS does not work on Voice and Quality of Service Features for ADSL on Cisco 2600 and 3600 Series Routers.
There is no work-around for this problem
Resolved Caveats—Cisco IOS Release 12.2(2) XK
There are no resolved caveats specific to Cisco IOS Release 12.2(2) XK that require documentation in the release notes.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.
Inquiries to Cisco TAC are categorized according to the urgency of the issue:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.
Cisco TAC Web Site
The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:
All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:
http://www.cisco.com/register/
If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.
