This topic presents examples of port densities that can be achieved when configuring AG boards for developing voice, fax, and conference applications:
The following AG board port density examples assume:
IVR requires:
|
Capabilities |
MIPS |
DSP modules |
|---|---|---|
|
Echo cancellation (16 ms window length, 400 ms adapt time) |
3.63 |
echo.m54 |
|
DTMF and silence detector |
1.94 |
dtmf.m54 |
|
Call progress |
1.06 (AG 2000 only) |
callp.m54 |
|
Precise tone filter (2 single frequency or 1 tone pair) |
1.25 |
ptf.m54 |
|
NMS record 32 Kbit/s |
3.38 |
voice.m54 |
|
|
Total: 11.26 MIPS per channel |
|
For a 100 MIPS device (90 MIPS effectively), the required number of IVR channels is eight (90 divided by 11.26 and rounded to the nearest whole number).
Fax could be used either in reception or transmission in V17, V27, or V29, requiring eight channels per DSP.
NaturalConference can support 16 members per DSP with all capabilities activated (10 ms echo cancellation window length).
The following table provides AG board port density examples:
|
Board name |
Channels |
NaturalConference ports |
|---|---|---|
|
AG 2000/200-8L AG 2000C/200-8L AG 2000-BRI/200-8L |
8 IVR channels |
16 ports of NaturalConference with echo cancellation, DTMF clamping, and tone clamping. |
|
AG 2000/200-8L AG 2000C/200-8L AG 2000-BRI/200-8L |
None (when using a dedicated conferencing resource board.) |
48 to 92 ports of NaturalConference. |
|
AG 2000/400-8L AG 2000C/400-8L AG 2000-BRI/400-8L |
8 IVR channels and 8 FAX channels |
32 ports of NaturalConference with echo cancellation, DTMF clamping, and tone clamping. |
|
AG 2000/400-8L AG 2000C/400-8L AG 2000-BRI/400-8L |
None (when using a dedicated conferencing resource board.) |
48 to 96 ports of NaturalConference. (Due to memory limitations of the coprocessor program of the AG 2000/C and AG 2000-BRI boards.) |
