Register Signaling
In the R2 protocol, register signaling is used during the call setup process to exchange
information about the calling and called party numbers and the calling party category. You can
use IMAT to define any of the specific tones used in R2 register signaling.
R2 register signals are defined as either forward or backward signals. Forward, or outgoing,
signals are generated by the originator of a call. Backward, or incoming, signals are generated
by the terminating end of a call. Forward and backward signals are grouped into the categories
shown in the following table.
When you are defining the specific signals in each group, the IMAT menus list each tone number
and the corresponding signal token. The following tables list the tokens in each group, and their
meanings.
