LBRCodec
Description
This parameter is used for selecting the low-bit-rate codec. The following values are valid:
• 0—Select G.723.1 as the low-bit-rate codec (available only for connections 0 and 2).
• 3—Select G.729A as the low-bit-rate codec (available only for connection 0).
If LBRCodec=0, then both Cisco ATA FXS ports can operate with the following codecs:
• Number of codecs=3
• Codec[0]=G.711µ -law
• Codec[1]=G.711A-law
• Codec[2]=G.723.1
If LBRCodec=3, check the setting of bit 21 in the ConnectMode parameter (see the “ConnectMode”
section on page 5-13) to determine if G.729 is enabled for the Phone 1 or Phone 2 FXS port.
If LBRCodec=3, then the Phone 1 FXS port can operate with the following codecs:
• Number of codecs=4
• Codec[0]=G.711µ-law
• Codec[1]=G.711A-law
• Codec[2]=G.729 (only if Bit 21 of the ConnectMode parameter is set to 0)
• Codec[3]=G.729A
If LBRCodec=3, then the Phone 2 FXS port can operate with the following codecs:
• Number of codecs=3
• Codec[0]=G.711µ-law
• Codec[1]=G.711A-law
• Codec[2]=G.729 (only if Bit 21 of the ConnectMode parameter is set to 1)
