8.3.2. Verifying Output Signals from EMR Modules
The EMR AES and analog output modules provide an internal tone generator that can be used to validate
the hardware, rear plate connection, wiring and patch panel (if applicable) of the output path. By using the
internal tone generator it is not necessary to prove the path to an input device and through the crosspoint.
8.3.3. Verifying Input Signals to the EMR-IP16-MADI
The EMR-IP16-MADI provides status information regarding its MADI inputs via front card edge LEDs.
Details regarding the behavior of the LEDs are explained in section
8.4.
MAGNUM CONFIGURATION
8.4.1. Verifying Tieline Definitions
As discussed in section
6.1.4, all TDM connections require an equivalent tieline definition in Magnum. If a
tieline has not been defined, or its definition does not match that of the physical connection then the
corresponding components will not work. It is important that the two are cross-checked to ensure
compatibility as the server does not do any automatic checks to ensure accuracy.
8.4.2. Verifying Source Availability
In order to route any source to a specific destination, the source must be explicitly made available to the
destination using Magnum. This is especially true if the system consists of EMR modules and EQX
modules. The EMR AES and analog sources must be made available to the EQX destinations that are
embedding destinations, and the EQX sources that are de-embedding sources need to be made available
to EMR AES and analog destinations.
When configuring source availability, if the desired source does not appear in the list, it is a good
indication that the tieline has not been defined correctly.
For systems with multiple EMR input and output modules, ensure that sources from every input module
are made available to every output module.

TROUBLESHOOTING CHECKLIST
When encountering any problems, use this checklist to quickly assess the situation:
1. Are all TDM connections secure and solid?
2. Is a common reference being applied to all parts of the system?
3. Does the input signal reach the input module in question?
4. Does the output signal reach the final destination in question?
5. Are the tielines defined?
6. Is the source available to the destination in question?
