Feature description

In some situations, customers require special auxiliary devices such as
bells, buzzers, or lights to be connected through the system. These devices
are activated through a regular 500/2500 Line Card and its associated
data block.

Operating parameters

A C4A ringer, or any other special signaling device that can be activated by
a 20 Hz ringing signal, can be equipped through the 500/2500 Line Card.

A maximum of five C4A ringers or equivalent devices can be configured
on one Terminal Number. This limit depends on the device’s impedance
to the 20 Hz ringing.

Feature interactions

Mixed DNs

If the DN associated with the signaling device appears on analog (500/2500
type) or Meridian 1 proprietary telephones, the telephone can answer or
connect into an active call.
