Can I run 56K RS-232 with a General Datacomm 500F AXR CSU/DSU?
A. The General Datacomm 500F AXR CSU/DSU has both a V.35 and RS-232 connector. As per the Technical Support of the GDC, the RS-232 port can only be used on 19.2 and slower lines. The V.35 can be used at 56K and 64K. The RS-232 port cannot handle a 56K line. If customers need this capability, they should get a 500C UXR.
