Cisco 700 Series ISDN Access Routers

Field Notice: Cisco 760 and 770 Routers Were Shipped with NET3 Software

February 25, 2000

Products Affected






Problem Description

The CISCO762M-US, CISCO765M-US,CISCO766M-US, and CISCO776M models were shipped with version 4.4.1 CE (NET3 image) software instead of the 4.3.1 US version of the software.


Due to a configuration rule error, some of the 700 series models were shipped with the wrong default software. If the customer specifically ordered software (that is, the customer requested software other than the default software), then the unit was shipped with the correct software.

Problem Symptoms

Users cannot configure ISDN on the affected units.


Verify the software version by issuing the version command. If the software version contains a ".NET3" then replace the image with the US version (the software version followed by a ".US").
