Is it possible to capture all trafic without select timeslots for individual points in a multipoint frame relay link and leter see each individual point?, or I only could have the trafic if I select the timeslots corresponding to each point?.

Regards
 
Can you clarify? Are you referring to having a trace file that shows the state or status of the frame relay traffic at each point through the WAN cloud in between the two end points? I'm not very WAN savvy but it seems unlikely that you could do this unless you get the service provider to perform captures for the various points at which the traffic is handed off as it traverses their network.

nPo Visualizer (the newest release) is supposed to do multipoint analysis but I'm not sure if it's applicable to frame traffic - I'd check with your local NAI SE to verify this.

No, I wasn't clear, there is

When I have a point - multipoint E1 frame relay link, I can see IP traffic when I select the X timeslots of the 31 slots in a E1 link, e.g. I use timeslots 2,3,4, and 5 for a 256 kbps link to a branch in the south and timeslots 6 and 7 to a branch on the north with 128 Kbps, of cuerse my carrier controls this but the sniffer can monitor if I assign this in the WAN tab I can see this, but my question is ¿If I capture all timeslots can I isolate traficc from a specific timeslots?.
 
Again, I'll defer to someone more WAN savvy than me but I believe that if you are using the Sniffer t1/E1 product, you can look at individual DS0's in post-capture mode and separate them for viewing purposes by setting up a display filter. The tap or access kit that sits in the T1 link makes this possible (again - this is my impression only - I can't absolutely verify it but am reasonably sure).

If you're using a WAN serial Sniffer to look at the traffic of a T1/E1 on the analog side in between the router and the CSU.... the WAN Serial Sniffer can NOT see individual DS0's.

Assuming that different timeslots represnet differnt DS0's, hopefully this points you in the direction of an answer.
