These release notes document important information about the interface cards supported on the Cisco 2010 Connected Grid Router (CGR 2010, or router) and the Cisco IOS software required to use the cards with the router. This document contains the latest information about limitations, restrictions, and caveats that apply to using the interface cards with supported platforms.
This document includes only the information and caveats that are specific to using the interface card on the router. The cross-platform release notes contain complete information and a list of caveats for the Cisco IOS release that supports the interface cards and the router.
Caution You must read the regulatory compliance and safety information for the router before installing the interface card in the router. This information shipped with the router and is also available online at www.cisco.com/go/cgr2000-docs.

For instructions on how to upgrade the router operating software, refer to Upgrading to a New Release in the Cisco IOS Cross-Platform Release Notes.
To determine the router software version, refer to Determining Your Software Version in the Cisco IOS Cross-Platform Release Notes.
Tip This document must be used with the appropriate Cisco IOS Cross-Platform Release Notes for the interface card. This document includes only the information and caveats that are specific to using the interface cards on supported routers. The cross-platform release notes contain complete information and list of caveats for the software release supported on the router and the interface cards.
Note For all known limitations for the software releases that support the interface cards, refer to the appropriate Cisco IOS Cross-Platform Release Notes for the interface card (see software links in New Software Features).
- Cellular networks support only outgoing calls on the interface card. The interface card cannot receive calls over the cellular network.
- The throughput rate on the interface card varies, and is affected by:
You must download, install, and execute the scripts described in this section to use the CG LTE interface card with the CGR 2010 and Cisco IOS Release 15.1(4)M4. The scripts address the following known issues that can occur with the interface card:
- Access Point Name (APN) —To use the interface card on Verizon cellular networks, the interface card APN must be changed. Cisco provides a script to automate the APN change for the interface card 3G and 4G wireless profiles. For detailed information about this issue, and how the script resolves the issue, refer to the documentation bundled with the scripts.
- LTE Modem Out-of-Sync State —In some cases, the card’s cellular interface appears to be up, but no longer sends or receives data. Cisco provides a script that configures Embedded Event Manager (EEM) on the router to automatically recover the interface when this issue occurs. For detailed information about this issue, and how the script resolves the issue, refer to the documentation bundled with the scripts. The section Open Caveats lists the bug ID numbers for this issue.
Note For additional open caveats for the Cisco IOS releases that support the interface cards, refer to the
New Software Features section for the appropriate software release.
Symptom: In some cases the show cellular command output might show incorrect data. The Current Service Status might be displayed as “No Service.” The value for Mobile Country Code (MCC) and Mobile Network Code (MNC) might be displayed as 0.
