Firmware Images
For each VXSM card type (OC-3, T1/E1, or T3), two firmware images are available, namely,

The Non-CALEA image supports three Media Gateway Call Control (MGC) protocols, namely, H.248,
MGCP, and TGCP. However, the image supports only one protocol at a time. The user must choose

setrev command.

later) so long as the original and the upgraded images are of the same version (for example Non-CALEA,
TGCP to Non-CALEA, TGCP). When loading or upgrading a boot or runtime image to a VXSM card,
