Product Summary

The XE1276A is the successor to the XE1276. Several improvements have been incorporated in the XE1276A. Power consumption has been reduced, an automatic Sleep mode has been added and the XE1276A includes non-volatile memory for storage of the "AT" Commands used for modem control and configuration. The XE1276A provides a replacement for the CH1776. Most OEM currently using the CH1776 can use the XE1276A without altering their existing hardware or software. The XE1276A includes user transferable FCC Part 68 registration. This permits use of the XE1276A without additional FCC Part 68 testing.
