NovaTec Network Multiplexer – NNM

The NovaTec Network Multiplexer NNM enables up to 256 B-channels with max. 6 primary rate interfaces (PRI/ISDN 30) to be split between several basic and primary rate (BRI, U or PRI) interfaces and  NovaTec SIP Gateway. By using CCU6 it will be possible to use up to 512 B-channels. This means pure ISDN or analog connections only.

Following ISDN interfaces are available:

• S0 interfaces for the connection of ISDN end devices or ISDN trunks
• PRI interfaces, e.g. to transfer unneeded B channels to a linked PABX
• U-interfaces in order to connect ISDN end devices with U interfaces to bridge long distances via copper wire.
• Conversion of existing S0 interfaces into U interfaces for networking of ISDN terminals over long distances.
• Analogue interfaces for the connection of analogue end devices

 

The NovaTec Network Multiplexer offers extensive configuration possibilities including:

• Allocating the B channels to all the interfaces listed above
• Preventing internal connections to be made with external connections
• Allows the setting of restrictions on the number of B channels on the respective BRI or U interfaces.

Using NovaTecs’ multiplexer and demultiplexer solutions for network and internet providers, individual client-side connection configurations may be developed from 2 Mbit/s data streams for permanent or dialled connections or a mixture of both.

Nearly every conceivable configuration may be achieved because of the modular construction and the high configurability of the device.

Every system in this series features a central processor. They may be equipped with PRI/ISDN 30, S0, Uk0 or analog interfaces and may be maintained remotely via IP or locally via a USB interface (V.24 in case of CCU3).

 

Possible users:

• Network Providers
• Middle or larger size companies

 

Operational applications:

• For connections of several ISDN 2 (BRI) devices, or from one server via an PRI/ISDN 30 interface to another server
• For multiple users in one building
• For the connection of fax servers, call centers, voice servers, etc.
• As a middle-box to solve compatibility problems on the ISDN level between two devices
• Broadband access divible into required narrowband connections

The individual systems NNM S5+, S6, S20 differ by the number of modules and thus the number of interfaces. All systems have the following features:

• IP access for service, maintenance and diagnostics
• NAMES can be used on all systems.
• Easy to install and to put into operation
• Modular construction concept, thereby individually profiling and changeable
• Future-proofed due to modular design concept, e. g. by using newly developed interfaces and networks.
