Installation and Programming
IP phone firmware is automatically downloaded from the 3300 controller to
the IP Phones (requires a DHCP server configured with options 128-133).
You can also download firmware to the telephone by plugging it directly
into an Ethernet port on the 3300 controller. The controller must be running
Release 7.0 or later to provide LLDP-compliant firmware to the telephone.
Install Line Interface Modules
The Line Interface Module (LIM) provides analog operation to the 5220 IP
Phone (Dual Mode), 5224 IP Phone, 5235 IP Phone, 5330 IP Phone, 5340
IP Phone, or 5360 IP in the event of an IP connection failure. Follow the
instructions in the Installation Guide that is included in the module package
to install a Line Interface Module. Refer to “Program Emergency Services
for a Line Interface Module” in the System Administration Tool Help.
Install and Configure Music on Hold
There are three types of Music on Hold available to the system,
embedded, analog, and digital. Program music on hold in the System
Administration Tool. Refer to the online Help for instructions.
Embedded Music on Hold is provided by audio files that are imported into
a single controller using the System Administration Tool or into multiple
controllers using Enterprise Manager.
An Embedded Music on Hold (MOH) source in use consumes an E2T
resource and each MOH session consumes an E2T resource.
Analog Music on Hold is provided by an external music source
connected to any one of the following:
Music on Hold connector on the back of a Universal ASU (see
Table 44 on page 264)
Music on Hold connector on a peripheral cabinet E&M trunk card
Digital Music on Hold is provided by an external music source connected
to a DNIC Music on Hold/Pager Unit (DMP). A peripheral cabinet is
required. The DMP is connected to a DNI line card.
Note: When a resilient hot desk device rehomes to a switch that has newer
device firmware, the user (including hot desk ACD agents) is automatically
logged out toallow the firmware upgrade to proceed
Note: The MXe Server supports embedded MOH only.
