Frame relay can be a "full T1". I believe you want to ask if Chris is
running "PtP T1s". ;-)
Some providers do something like this:
* Order PtP T1 from telco
* Terminate on "magic box" that speaks FR to downstream
* "Magic box" speaks ATM to ISP core network via uncongested OCx.
Note that this is totally different than running over a telco-provided
frame cloud. Providers can offer/deliver 100% CIR. One can verify
100% CIR by confirming lack of FR drops on the router interface.
OTOH, consider that an HDLC T1 could secretly be converted to ATM or
MPLS, statmuxed, and oversubscribed. Search for:
AToM HDLC
for more information.
Bottom line: "Frame Relay" isn't _ipso facto_ evil. Check your
interface statistics, regardless of line protocol. :-)
