The only thing I hate worse that the Lucent modem DSPs and code is Cisco
modem DSPs and code. MICA stinks.
I particular love the Cisco MICA kludge of auto-firmware downloads after
X number of connect failures on a modem. I'm not sure why re-downloading
firmware to the DSP is going to improve connect performance. I guess the
the Cisco MICA DSPs corrupt their own code, leak memory, or just lockup
once in a while. Anyhow, since each DSP provides 6 modem channels, the
auto-download procedure will take down 5 channels over and above the one
that was causing problems. If some of the other 5 channels are in use, it
will wait and busy out the channels until they are all free, and then
proceded re-downloading the firmware. Now if this means that you don't
have enough modems to handle calls, the Cisco will helpfully return busy
signals. This is why you should always have 6 extra modems in a Cisco.
