I would suggest also different provider equipment. If one provider uses J find your second provider that uses C.
Also don't be seduced by a provider that offers 2 disparate paths, using two totally different systems. I remember years ago AT&T's ATM and FR systems both died nationwide due to some equipment bug.
Also providers lie either intentionally or by mistake. If they state a circuit is protected, it might be this month, but next month it may not be. You may only discover this 3 years from now when the circuit dies, and the provider is happy to pay the SLA penalty which is far less than the 3 year cost of a protected vs a non-protected circuit.
