Configuring analog E&M line failure tone

As shown in Figure 12, E&M analog control signals pass-through is enabled for the analog E&M line on Router A. To notify an IP network failure or a peer failure to the Tone Generator, configure Router A to play busy tones for analog E&M line failure by using the em-failure busytone command.

Before performing this task, make sure that both the E&M non-signaling mode and the E&M analog control signals pass-through are enabled for the E&M line. For more information, see "Enabling E&M non-signaling mode" and "Enabling E&M analog control signals pass-through."
