NOTE 1 — flow control problem. Both the MTDM and the 7400A expect XON/XOFF flow control when
running 19.2 Kbps.

NOTE 2 — works but not cost effective (RS232 modems should be running 19200 also).

NOTE 3 — not tested and not cost effective (modems should be running 19.2). Voice messages can
emulate XON/XOFF. This results in lost data and dropped connections.

NOTE 4 — not tested because not cost effective (424 not off the shelf compatible with 7400A in a rack
mount).

NOTE 5 — not recommended since MTDM is being manufacture discontinued.
