Analog Voice Module (AVM)
Prior to connecting the Analog Voice Module (AVM), ensure that the interface
type/signaling convention has been properly strapped (refer to Section 8, “Analog
Voice Modules”). The connection procedure is identical for modules with either
single or dual channels, although modules with the dual channel feature may be
configured for two different types of signaling conventions.
