Introduction
These modules consist of extensions and external analog lines for expanding the number of
analog interfaces (A/B) for standard telephones, analog trunks and additional equipment (TFE
interface, and others).
There are modules with only trunks, trunks and extensions and only extensions. For modules
with trunks and extensions, in the event of a power outage, there is a circuit that switches the
available trunks to their respective slots on the extensions.
