500 MGI Card & Procedure
Note that some of the following options may not apply to the card being programmed (MGI1,
2 or 3).
AUDIO CODEC
Selects which audio codec compression to use. Selections are G.711
(64K), G.723.1 (6.4K), G.729A (8K) and G.729.
ECHO CANCEL
Enables or disables echo cancellation (0: disable, 1:enable). This
function removes echo that is generated by voice reflection and
packet delay.
SILENCE SUPPRESS
Determines whether silence suppression is used (0: disable, 1: en-
able). This prevents transmission during the silence period of a call.
INPUT FILTER
Selects input filtering of the DSP (0: disable, 1: enable). This should
be set to ON.
OUTPUT FILTER
Selects output filtering of the DSP (0: disable, 1: enable). This should
be set to ON.
INPUT GAIN
PCM input gain value of DSP. The range is -31dB to 31dB (0–63).
This sets the volume of PCM voice from the VOIP DSP to the site.
VOICE VOLUME
Selects the voice volume. The range is -31dB to 31dB (0–63).
FRAME COUNT
This option selects the number of frames the MGI will consolidate in
the packet message. The voice packets are buffered to the set num-
ber and sent as a single packet. The range is 1–12.
JITTER OPTION
Selects the dynamic jitter specific value. Value determines whether
the focus is on packet loss or packet delay. The range is 00–12.
MIN JITTER
Sets minimum value for jitter buffer.
MAX JITTER
Sets maximum value for jitter buffer.
FAX ECM
Sets additional recovery function for FAX transfer errors when using
T.38 Fax.
MAX FAX COUNT
Sets maximum number of allowed Internet FAX channels.
DTMF TYPE
Sets whether to transmit the DTMF signal through the voice channel
(INBAND) or through a separate message (OUTBAND).
TOS FIELD
Defines Type of Service packets.
