3745 and DS-3 support

[news2010a]

Hi, imagine I need to make sure I have a router available to work with DS3 circuit on remote site.

A remote field technician tells me there is a 3745 router with "HSSI" and external Adtran CSU/DSU available.

Is that an indication this can work with DS-3 circuit?
Which specific Adtran CSU/DSU do I need in order to make it work with DS3?

Yes, HSSI is DS-3. If don't have the CSU/DSU, any model will do.
