Configuring R2 signaling
Introduction to R2 signaling
ITU-T recommendations Q.400 through Q.490 define the R2 signaling standards. However, the R2
signaling standards implemented in different countries and regions are ITU variants.
R2 signaling includes two categories: digital line signaling and interregister signaling. Digital line
signaling conveys status information about E1 trunks to describe whether the trunks are occupied,
released, or blocked. Interregister signaling transmits such information as address in multi-frequency
compelled approach. Generally, the calling side serves as the originating PBX and the called side serves
as the terminating PBX. Signals sent by the originating PBX are called forward signals and those sent by
the terminating PBX are called backward signals, as shown in Figure 18.

ITU-T digital line signaling
Digital line signaling is responsible for changing call statuses and conditions of a line. It functions to
identify and detect these four states: calling party goes off-hook and seizes the line, called party goes
