McTi-MR Telephony Interface Pin Assignments
To test internal McTi-MR connections, jumper the following pins together on the
Digital Connector Block for the McTi-MR boards installed in the slots indicated:
Slot 2
pins 1-2
pins 26-27
Another way to test McTi-MR connections is to use a loopback connector (DB15P
male) attached directly to the digital connector with pins 1 & 3 and 9 & 11 jumpered
together. A successful test will result in all McTi-MR board front panel LEDs off with
the exception of the "Active" LED which should be blinking.
Refer to MOP 308 for detailed McTi-MR loopback instructions.
