Universal Analog Voice Module
The Universal Analog Voice Module (UAVM) consists of two channels into which
one of the four voice interface modules (E&M, FXO, FXS, or Voice/Fax Switch
module), is inserted. The Universal Analog Voice Module must be configured
with the correct jumper settings for the types of interface modules you plan to
use before you can connect the modules to the network. Voice interface modules
can be connected with either RJ-11 modular cables or with a direct connection
to a terminal block.
The Universal Analog Voice Module consists of a motherboard and one or two
interface modules (see Figure 6-9 below).
