2. PHYSICAL DESCRIPTION OF THE UNITS.
In order to understand the installation and cabling process associated to each unit, first you
need to be familiar with the connectors and other specific elements of the AoIP solution
described in this manual and the equipment front and back panels.
2.1. NETBOX 32 AD interface physical description.
2.1.1. Description of the front panel.
There are indicators related to the unit status, communications and audio levels.
POWER ON LED: indicates the status of the unit power supply.
•
Off: no mains input.
•
Green: power supply ON.
LAN LEDs: indicate the status of the audio local area network: LAN 1 (main interface)
and LAN 2 (secondary interface).
Status:
•
Off: no local network connection.
•
Blinking green: link is established at data level.
If the boards are wired to a dedicated audio network using a switch, only LAN 1 should
be blinking. If the wiring is connected in "Daisy Chain" mode, without switches, or there
is a redundant network, both LEDs should be blinking. IMPORTANT NOTE: When there
is a redundant network, primary and secondary interfaces must be connected to
separated networks.
AUDIO LEVEL LEDs: Each LED indicates the level of the corresponding device audio
input / output:
•
LED off: the channel is muted, or transmits or receives (depending on whether
it is an output or an input) at a level below -60dBFS.
•
Green LED: channel is transmitting or receiving audio (depending on whether it
is an output or an input) at a level between -60dBFS and -20dBFS.
•
Amber LED: channel is transmitting or receiving audio (depending on whether it
is an output or an input) at a level between -20dBFS and -6dBFS.
•
Red LED: the channel is saturated or "clipping" (above -6dBFS).
On / Off switch.
