The Voice mode in the system menu (Figure 10 and Figure 11) controls whether
the SHARK™ IAD is in a Central Office (CO or network) environment or a
Customer Premise Equipment environment (CPE). Only a user who has logged
in using the system administrator password can change this mode. The
SHARK™ IAD is factory shipped in the NETWORK Mode.
Note on Network or
CPE Voice mode To comply with specific FCC requirements the functionality of the Voice
modules has been separated into network and CPE modes.
Do not operate the SHARK™ IAD in the Network Voice mode while it is
installed as CPE equipment at a customer's premise.
Doing such is a violation of your SHARK™ IAD's FCC licensing
E&M System
Settings The Voice system menu also configures the common E&M parameters for the
voice modules. NOTE: The following E&M settings apply to only and all
channels configured to an E&M signaling mode. See Voice Configuration
Pages (page 5-57).
