L2TP between Cisco and Juniper

Hi, our customers with remotes site connecting back to their HQ thru MPLS connection as a primary. They have a single PRI which will dial-back to the our MPLS backbone (AS5400 Universal Gateway)...I've a question to clear at this stages.

i. Since the ISDN PRI dial-up are dialing to a Cisco AS5400...there's a problem whereby our MPLS backbone is built on Juniper platform, in order to re-establish all the existing remote site's connection, the AS5400 need to have either a L2TP or a VPDN to the Juniper that right? and if so, how shall I implement the AS5400 so that it can work in conjunction with the Juniper PE? I tried to look at the Juniper PE (either a M10i or ERX700), it just support l2tp dialout whereby i can't see any dial-in options available? does that means that the ERX700/M10i does not support the L2TP dial-out from the AS5400?

I'm very new to these kind of ISP backbone thingy, but would like to know if you guys face the situations like this, what's the best practice?

Thanks and appreciate if someone here could help
