Cross connecting two routers with channelized interfaces

[diogo.montagner at gmail.com (Diogo Montagner)]

Hello,

sorry for this dumb question.

Is it possible to connect two routers like below ?

RouterA/cstm1 ---- dark fiber ---- cstm1/RouterB

The interfaces used in this case are channelized STM1 in both sides.
Between RouterA and RouterB I would like to create many low-speed
interfaces ranging from 64Kbps up to 2Mbps. Between these two routers
there is no MUX.

The framing mode has to be SDH.

Thanks in advance!
