1. DESCRIPTION
1.1. The IMB2000C01
The IMB2000C01 module is a 256 input by 192 output digital audio matrix with AES10,
commonly known as MADI, and AES67 interfaces integrated into the module. Optional
AES/EBU and analog interfaces are available via additional modules installed in the same
mounting frame. The digital audio format managed by the matrix is 24 samples per
second at 48kHz.
The module provides one input and one output for MADI audio via BNC connectors
labelled MADI IN and MADI OUT through which up to 64 channels of audio can be
transmitted and received. There are also two 1Gbit/s Ethernet ports labelled ETHERNET
1 y ETHERNET 2 through which up to eight streams of AES67 audio can be transmitted
and up to 16 streams of AES67 audio can be received with a maximum of eight audio
channels per stream. Finally, the module has a connection to the AUDIOFLEX bus of a
UR2000 mounting frame over which up to 64 channels of audio can be transmitted to
and received from other modules installed in the frame.
AUDIOFLEX is a bus provided by the UR2000 mounting frame and formed by two lines,
M2S (Master to Slave) and S2M (Slave to Master), that interconnect all the slots of the
frame. Each of the two lines can multiplex up to 64 audio channels sampled at 24 bits
and 48kHz, grouped into eight time slots of eight audio channels each.
The IMB2000C01 module has been designed to operate together with the ADB2008C01,
DAB2008C01, DDB2008C01 and DEB2008C01 modules. They use the two lines of the
AUUDIOFLEX such that, when properly configured they create a switching matrix for
audio signals in multiple formats: analog, AES/EBU, AES67 and MADI.
Synchronization of the IMB2000C01 module is performed via any of its Ethernet
interfaces using IEEE std 1588, also known as PTP, as per the specifications of the AES67
standard. The IMB2000C01 has predefined profiles for the most common applications,
and a custom profile can also be defined with the key parameters of the protocol for a
specific application.
It is possible to monitor the IMB2000C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The IMB2000C01 is a TL2000 terminal line module and can be housed in a two rack unit
(2 RU) UR2000 mounting frame.
