Configuring E&M non-signaling mode

The E&M non-signaling mode is applied when the E&M interface of the peer device does not provide the

M line and E line. In this mode, the E&M interface communicates with the peer device without signaling.

You can configure the PLAR function by using the private-line command to form a three-segment E&M

virtual private line (E&M-VoIP-E&M). When a subscriber picks up the phone, the originating device

directly dials the number specified by using the private-line command.

To configure E&M non-signaling mode:

Enabling E&M control signals pass-through

This feature operates only when the E&M non-signaling mode is enabled. As shown in Figure 6, an E&M

virtual private line is set up between the tone generator and the radio. Enable E&M control signals

pass-through for Router A and Router B so that they can send seize and idle signals for the E&M virtual

line over the IP network.
