(PM) Medium-density 56/64K leased solution?

Does livingston make any equipment that will do SYNC 56 or 64K connections
except for the OR-U?

I'm trying to decide what the next step is for handling a moderate number
of 56k leased line connections. The "Office Router" is a good product but
only offers a single sync serial port per unit, I'm hoping somebody can
suggest a slightly higher-density solution (2,4 or 6 ports), something
under the $800/port cost of the only current alternative, adding a high-speed
serial port to an existing Cisco router.

If I was looking at doing a dozen or more of these leased line connections
I'd just bit the bullet and move to frame relay, but ISDN has really done
a number on the interest in low-speed permanent circuits...

If only the Portmaster-2e could do Sync-serial I'd be set-

There is an Adtran CSU/DSU that will do the sync->async conversion,
but it appears that it is really meant to carry a 57.6 async data stream
over a 64K leased line when used in pairs, not to just convert the ISP side
into async for a terminal server while the other end has a Livingston-OR,
Pipe-130, or Cisco-100x?
