Version 6.6 687 Mediant 2000
User's Manual 45. Configuration Parameters Reference
45.15 IP Media Parameters
The IP media parameters are described in the table below.
IP Media Parameters
Parameter Description
Web: Number of Media
Channels
EMS: Media Channels
[MediaChannels]
Defines the maximum number of DSP channels allocated for various
functionalities such as IP-to-IP sessions.
The RTP streams for IP-to-IP calls always transverse the device and
two DSP channels are allocated per IP-to-IP session. Therefore, the
maximum number of media channels for IP-to-IP calls is 240,
corresponding to 120 IP-to-IP calls.
The default is 0.
Notes:
 For this parameter to take effect, a device reset is required.
 Other DSP channels can be used for PSTN interfaces.
Automatic Gain Control (AGC) Parameters
Web: Enable AGC
EMS: AGC Enable
[EnableAGC]
Enables the AGC mechanism. The AGC mechanism adjusts the level
of the received signal to maintain a steady (configurable) volume
level.
 [0] Disable (default)
 [1] Enable
Notes:
 This parameter can also be configured in a Tel Profile.
 For a description of AGC, see Automatic Gain Control (AGC) on
page 175.
Web: AGC Slope
EMS: Gain Slope
[AGCGainSlope]
Determines the AGC convergence rate:
 [0] 0 = 0.25 dB/sec
 [1] 1 = 0.50 dB/sec
 [2] 2 = 0.75 dB/sec
 [3] 3 = 1.00 dB/sec (default)
 [4] 4 = 1.25 dB/sec
 [5] 5 = 1.50 dB/sec
 [6] 6 = 1.75 dB/sec
 [7] 7 = 2.00 dB/sec
 [8] 8 = 2.50 dB/sec
 [9] 9 = 3.00 dB/sec
 [10] 10 = 3.50 dB/sec
 [11] 11 = 4.00 dB/sec
 [12] 12 = 4.50 dB/sec
 [13] 13 = 5.00 dB/sec
 [14] 14 = 5.50 dB/sec
 [15] 15 = 6.00 dB/sec
 [16] 16 = 7.00 dB/sec
 [17] 17 = 8.00 dB/sec
 [18] 18 = 9.00 dB/sec
 [19] 19 = 10.00 dB/sec
 [20] 20 = 11.00 dB/sec
