How to understand and configure E1 R2 signaling

[TCC_2]

Resolution

These are two main elements to R2 signaling:

• Line signaling: supervisory signals
• Interregister signaling: call setup control signals

For an introduction to E1 R2 signaling, refer to E1 R2 Signaling Theory.

This information can be found in the E1 R2 Signaling Theory document:

• Three types of E1 R2 line signaling are R2-Digital, R2-Analog and R2-Pulse.

  For more information, refer to the Line Signaling (Supervisory Signals) section.

• Three types of E1 R2 interregister signaling are R2-Compelled, R2-Non-Compelled and R2-Semi-Compelled.

  For more information, refer to the Interregister Signaling (Call Setup Control Signals) section.

For more information on configuring E1 R2 signaling, refer to these documents:
