Monitoring the E1 lines with bantam jacks
Each E1 card provides transmit and receive bantam jacks to monitor the status of the E1 lines.
The Tx line carries what the MAX TNT unit transmits to the network. The Rx line carries what
the unit receives from the network. The bantam jacks do not interfere with the signal either
coming into or going out of the unit.
