Hi,
The FDDI PID mentioned that the external bypass switch can be ordered
from AMP and the jack of the switch is MMJ. However, I have checked
with AMP that they only provide the following three types of
interfaces:
1. Modular Plug
2. DIN
3. MTE Receptacle
so none of them is MMJ. So what can we use ? Does anyone know the AMP
part no. ?
What patch cable (from AMP to our DECbridge/DECconcentrator) should we
use ? Pin-to-Pin or Cross-over (how) ?
Thanks in advance.

On a DECbridge 620, the Optical Bypass connector is MJ (RJ12)
not MMJ.
You could find the connector pinout in the DECbridge 620
installation manual. I copied below the pinout from the manual.
Pins
