There are CSU/DSU's that will also act as a sniffer for frame-relay ckts.
They usually are ungodly expensive unless your carrier provides it for you.
Visual Networks comes to mind as as a manufacturer of these little toys.
The amount you can capture is dependent upon the amount of mem in the csu.
Not the best one out there but works very well.
Good Luck,
Ben Parrish

RJ45 does not equal Ethernet. Are you thinking of placing an ethernet
hub there? If so, you have completely incompatible physical layers to
begin with. A T-1 signal from a csu/dsu or an NIU is going to wreak all
sorts of havoc on an ethernet hub, most likely.
You also have completely different datalink layers, so you can't expect
an ethernet sniffer to have the slightest idea what is going on inside a
frame relay frame on a DS1. This not unlike asking "Can I connect a
regular phone to an ethernet hub and listen in on a VoIP call?"
Completely incompatible technologies. You'd have to find a hardware
sniffer designed for frame relay.

The RJ45 connection between the DSU/CSU and the wall jack. Would
putting a
hub between the two work? Then I could place a sniffer on the hub.

Frame over serial? (T1/Ds1/Ds3) They would have to plug into a
Network
analyzer with a compatible interface, not a hub. Most hardware
network
analyzers have pass-through connections that let you plug through the
analyzer to the router.
Good Luck,

Quick question for you all. If you were to break a Frame Relay
connection going into a router by first plugging it into a hub, then
connecting it to the router, for the purposes of plugging a sniffer
into
that hub to monitor all frame traffic, would this scenario work or not
so
much? Thanks for your input!
