Yes. To use the new Lucent-based modem cards you will have to upgrade to a
new version of the ComOS. The new version still carries a modem image for
the existing cards, so you can upgrade the ComOS first, and then install
the Lucent-based cards as they become available. In fact, with the new
ComOS, you can even intermix existing and new modem cards within the same
chassis.
