B1 CNV
The B-channel 1 Conversion parameter allows you to choose Pulse-Code Modulation (PCM)
coding for B-channel 1 voice traffic. The values are off, ad-u, and ad-A. Use ad-u (µ -law)
when converting from T1 carriers, and use ad-A for E1 carriers (this signal is inverted A-law,
not regular A-law).
B1 RATE
The B-channel 1 Rate parameter allows you to choose both the speed of the B-channel traffic
and the position on the ADPCM time slot.
Two ADPCM engines must be assigned to each WAN time slot, and the rate combination of
both engines must be 64 kbps.
The values are n/a, 24k,1 (64 kbps to 24 kbps on the first ADPCM engine), 32k,1 (64 kbps to
32 kbps on the first ADPCM engine), 40k,1 (64 kbps to 40 kbps on the first ADPCM engine),
24k,2 (64 kbps to 24 kbps on the second ADPCM engine), 32k,2 (64 kbps to 32 kbps on the
second ADPCM engine), and 40k,2 (64 kbps to 40 kbps on the second ADPCM engine).
B1 ADPCM
The B-channel 1 ADPCM parameter allows you to choose the ADPCM card to which you
would like to assign this B-channel. The options are n/a, P1 (the ADPCM card in slot P1), P2
(the ADPCM card in slot P2) and P3 (the ADPCM card in slot P3).
B2 CNV
The B-channel 2 Conversion parameter allows you to choose PCM coding for the B-channel
2 voice traffic. The values are off, ad-u, and ad-A. Use ad-u (µ-law) when converting from
T1 carriers, and use ad-A for E1 carriers (this signal is inverted A-law, not regular A-law).
B2 RATE
The B-channel 2 Rate parameter allows you to choose both the speed of the B-channel traffic
and the position on the ADPCM time slot.
Two ADPCM engines must be assigned to each WAN time slot, and the rate combination of
both engines must be 64 kbps.
The values are n/a, 24k,1 (64 kbps to 24 kbps on the first ADPCM engine), 32k,1 (64 kbps to
32 kbps on the first ADPCM engine), 40k,1 (64 kbps to 40 kbps on the first ADPCM engine),
24k,2 (64 kbps to 24 kbps on the second ADPCM engine), 32k,2 (64 kbps to 32 kbps on the
second ADPCM engine), and 40k,2 (64 kbps to 40 kbps on the second ADPCM engine).
