Dynamic Modem
Dynamic Modem is a new configuration parameter created to Enable or Disable DSP
dynamically, switching to codec G.711 after a high speed or fax modem is detected.
An example of various high speed modems (which utilizes phase reversal in the
answer tone) are the V.32, V.34 and V.90.
Warning
The Dynamic Modem parameter is only supported on Texas Instruments (TI) DSP,
this includes:
• Vanguard 6560 - HDSM
• Vanguard 6400 Series - T1/E1 with DSP
• Vanguard 7300 Series - T1/E1 with DSP
• Vanguard Quad FXS/FXO cards
The enabling and disabling of the dynamic switching to G.711, after modem
detection, is configured at the voice port.
