An N3DX1 board does not support E&M signaling when the NE uses UPM boards.
N3DX1 supports the association of signaling and services.
None: not associate.
Signaling Reception: When the port reception status M wire is idle, the audio services sent to the cross-connection side are invalid; when the M wire is busy, the audio services are valid.
Signaling Transmission: When the audio services received from the cross-connect side are invalid, the port transmission status E wire is idle; when the services are valid, the E wire is busy.
Signaling Reception and Transmission: associates signaling with services in both the receive and transmit directions.
