timeslots;need 3 extra dsps to support the requested configuration
我的slot里面已经放了3条了，不知道为啥还不够。 |

发帖数: 1985 | 2 Why did you put 3 dsps for 2 PRI?
How many signal channels each PRI? What's the rate of each signal channel?

发帖数: 28013 | 3 After I put 3 dsps,put switch-type,pri-group, one pri is fine, when I config
the other one, error message shows only support 13 channels something like
that.
After increased dsps to 4, everything is fine.
Totally, there are 48 channels,the rate is by default,G.711? 64kbps?

发帖数: 1985 | 4 Actually the error msg already told us the answer. One DSP can only support
13 channels. So one T1 requires 2 DSPs to cover 24 channels. Two T1s means
4 DSPs.

1. DSP模块不同的型号差别很大，下面两个处理能力差8倍。
PVDM2-8: 0.5 DSP chip
PVDM2-64: 4 DSP chips
2. 不同的编码和业务对DSP的需求量也不同。
G711 属于medium complexity
G729 属于high complexity
cisco website有个地方可以根据应用情况计算需要的DSP模块。

发帖数: 1985 | 7 Yes, it definitely depends on what kind of DSP, and the codec required.
