ITNM Systems ALC100 DVB Audio Level Control
Integration in networks
The ALC100 is applicable in several kinds of network architecture.
Normally the system is placed at the location where centralised processing of digital radio and television services is performed; the head-end or digital play-out centre. There are many ways to connect, depending on the construction of the existing multiplexer and receiver equipment.
The DVB transmission is done by electrical or optical Gigabit Ethernet, or by ASI interfaces. Communications with the ALC100 for maintenance and SNMP is done by common Ethernet.
The drawings below show examples of implementation of the ALC100 in several kinds of network design. However, the possibilities are not limited to these examples.

Application fed by the receivers
In case it is not possible or not desired to connect through the multiplexer, then the ALC100 also accepts ASI input signals directly coming from the satellite receivers. For this, one or more ASI connections can be used.
Application fed by the multiplexer
The ALC100 can also be used behind the multiplexer for processing of the complete transport stream. The connection can be ASI or GbE.
Application fed by two multiplexers
Thanks to the big processing capacity of the ALC100, even multiple transport streams can be processed simultaneously by means of up to two ASI connections.
Application in a small multiplexer system
In a configuration of only one or a few transport streams, signals can be exchanged by efficient (Gigabit) Ethernet or one or more ASI connections.
Application in a big multiplexer configuration
Dependent on the composition of the signals and the amount of channels, one or more GbE or ASI connections from and to the multiplexer can be used. It is also possible to divide the traffic by means of an GbE switch. A spare ALC100 can optionally be applied working as a shadow and working as controller and monitor for the diversion of data.
