What’s the meaning of TDM bus 2k*2k?
Q: What’s the meaning of TDM bug 2k*2k?What’s the condition one analog card calling need CPU process?
A:
MSR2040,30 and 50 routers all have TDM bus. TDM bus consists of 32 8Mbps HO bus, and PSTN use 64kbps ADPCM coding/decoding, then bidirectional calling need 128kbps, so TDM bus can support 2048(32*8M=2048*128k).
2K*2k means can support 2k tunnel calling. The calling between one analog card interfaces like 4FXS will need PU process, and two different card don’t need CPU process.
