Hi,


We have two PRI and 4 BRI lines installed in our Cisco 7206. But we are using only 45 channels live in our PRI lines. Now when i tried to increase the time-slot from 15 channels to 30 channels for 1 PRI line, its giving error message. I like to know how many DSP channels/slots will be available in Cisco 7206 Router board. Please find below our router and dsp details.


Error Message:-


Cisco7206Router(config-controller)#pri-group timeslots 1-31



Current dsp resources can support 26 timeslots;need 2 extra dsps to support the requested configuration


Cisco Router 7206:-


cisco 7206VXR (NPE225) processor (revision A) with 114688K/16384K bytes of memory.

Processor board ID 23677191

R527x CPU at 262MHz, Implementation 40, Rev 10.0, 2048KB L2 Cache

Querying dsp status......

Do you have dspfarm configured currently ?

Do you have other E1 ports doing voice in the same router ?

You have two dsps shutdown. Take them out of that condition and if they prove faulty RMA the PA.
