Introduction 8 4 Introduction The AES-VMUX is used to transport a large number of digital audio signals. The module is both a multiplexer and demultiplexer and has 16 AES audio ports which may be used as inputs or outputs. The module forms the core of a highly flexible audio transport and routing concept. The audio transport has a fixed embedding and de-embedding delay of 64us. The audio signals are transported completely asynchronously and bit transparently.
Introduction 9 • PIN/Standard laser tranceiver The following Nevion video SFPs may be used but only one of the channels will be utilised. • PIN dual receiver • APD dual receiver • Standard short haul dual laser • CWDM dual laser The optical input provides an extra input and the actual input may be chosen automatically or set manually to the required input. In “Auto” mode, the input switches if a suitable signal is not present, or if the signal disappears.
Introduction 10 4.1.1 HW 1.1 enhancements Extra VCXO to allow input locking independant of output frequency. This gives the following:• Wider input jitter tolerance. • Master mode module will de-multiplex audio to its AES outputs regardless of loop status. i.e. System is more resiliant as a module may fail but the remaining chains of modules still present will still work. • More stable frequency of SDTI as the output frequency will not change until full lock is achieved. i.e.
Specifications 11 5 Specifications 5.1 Electrical SDTI Video standard 576/25i ITU-R BT.656 Error detection EDH according to SMPTE RP165 Input cable length Greater than 250m All other SDI parameters conform to ITU-R BT.656 5.2 Optical SDTI Optical range depends on the output power of the transmitter and the sensitivity of the receiver of the next module. See Nevion SFP datasheet available from support or the Nevion web site. 5.
Specifications 12 5.4.1 Slave modules HW 1.0 1.1 Video latency 0.56 us 0.85 us 5.4.2 Clock master module The master module has a buffer which may be up to 2 video lines or 128 us. The actual latency will depend on the latency due to the round trip which may be large if packetizing transports have been used or if the stream has been received via satellite. The Clock master module will then add as little latency as possible to round the total latency up to a multiple of two video lines.
Specifications 13 5.6 Input wander and jitter tolerance Slave mode Wander locks to the input clock so wander is not relevant. < 1 UI p-p. Jitter Master clock mode HW 1.0 Wander plus Jitter < 1 UI p-p. Master clock mode HW 1.1 Suitable for use with IP bridges etc. Wander 512 UI p-p. Jitter < 1 UI p-p. AES-VMUX/-SFP User Manual Rev.
Configuration 14 6 Configuration ON ON 1 Figure 6.1 8 1 8 Module DIP switches. The module DIP switches must be set up correctly. The module has 16 audio ports and the first thing to consider is the port directions. This influences all of the following steps. The three things that must set with the DIP switches are: 1. AES port direction 2. Input port embedding start address + Routing to the output ports may be controlled with Multicon GYDA if the ’DIP config mode’ is off.
Configuration 15 contain errors, if the wander is very large or periodically when the loop is not complete. This hardware version may be used for looped configurations where one or more of the module connections is over a link where wander is present on the output signal, i.e. IP or SDH video links. 6.1.1 SW2.6 Clock Master mode • On: Module is the clock master • Off: Module is a clock slave 6.2 Audio port direction The 16 audio ports are controlled in blocks of four ports.

Configuration 18 6.3.3 System address planning The number of timeslots in the multiplex used by the module depends on the number of input ports in the module. It is up to the user to ensure that the addressing is consistent and timeslots are not overwritten (unless this is intended). 6.4 Method 1. First define the port directions on each module. 2. Arrange each site so that the modules with de-multiplexing channels come first in the SDTI chain. 3.

Configuration 21 6.5.2 Example 2 Figure 6.4 Point to point 8 out and 8 back.- 2 Modules, 2 sites. Both modules are used for embedding and de-embedding and the SDTI signal is connected in a loop so one of the modules must be the clock master.

Configuration 22 6.5.3 Example 3 Figure 6.5 Point to point 16 out 16 back. 4 modules, 2 sites. The two signal directions do not share any channels so keep the SDTI chains separate. The two chains may then be configured identically. Table 6.9 Modules 1 and 3, demux 1-16 Port Directions SW2 1-3 on ,on ,on Demux start address SW1 1-4 off, off, off, off Mux start address Table 6.
Configuration 23 6.6 SDTI input control If an optical is present on the module the input selector may be manually set to one of the inputs or allowed to switch automatically. If in DIP configuration mode:- 6.6.1 SW2.4 Manual/Auto • On: Manual, input is fixed. SW2.5 setting is used • Off: Auto, input will search for a Network SDTI audio signal. SW2.5 is ignored 6.6.2 SW2.5 Optical/Electrical • On: Optical input is used • Off: Electrical input is used 6.
Configuration 24 6.8 Multicon control The module may be monitored and controlled with the Multicon system controller. Port direction and multiplexing time-slots may be monitored. Each de-multiplexer port / AES output is present in the audio matrix which may be controlled by the system controller. 6.9 Status Monitoring The AES digital audio signal presence for both multiplexer and de-multiplexer ports and the on-board power levels are presented on the info page.
