• Installing a DSP II module into a system already upgraded to Release
9.0 or later may generate a Check Bootrom or Check FPGA alarm
indicating that the firmware in the module needs to be upgraded. Use
the UpgradeBootrom ALL maintenance command in the System
Administration Tool to upgrade the firmware.
Table 56 shows the maximum number of G.729 and T.38 channels that
are available for use in a single DSP II module in the various systems. Note
that the base configuration in the CX/CX II includes the first 8 T.38
channels. A second DSP II module can be added in the MXe for more
G.729 channels, but the number of T.38 channels available does not
increase.
