Those MTS devices are Memorex 1270 devices (that's what MRXA means) and are not directly compatible with IBM 2703 devices, although similar. There is one DSR in MTS that supports both types, but it has to know which type it is talking to. You might get further if you patch the device type to "TTY " or maybe "2741" but probably not. George Helffrich recently got 2741 support working in D4.1 MTS running on simh emulating a 360/67. This isn't really directly relevant, but his experience might shed some light on how to make this work.

What, exactly, is Hercules emulating? A dial up TTY attached to a 2703? A dial up 2741 on a 2703? MTS supports both but needs to know which it is talking to. The device type in TABLES in MTS needs to be set appropriately. George also found a bug in the DSR that supports these devices. It has assembly parameters controlling whether to include support for 2703 and/or MRXA controllers. However if you turn on both options the 2703 support doesn't work right. By the time of D4.1 we no longer had any real IBM 2703's and so the DSR was never tested with them. Apparently it didn't work. George's solution was to reassemble TSFO with support for MRXA turned off. This made 2703 support work. He also had to fix a few minor bugs in simh which isn't relevant, but you might well find some incompatibilities between Hercules 2703 support and MTS. It would be nice to get this working in D6.0 since a simulated 2741 makes a nice terminal for some purposes. I've CCed you, George. Let me know if I've misrepresented anything you did.
