512 kbps ISDN connection
on demand		 The inverse multiplexer can establish a 512 kbps link between two ISDN subscribers worldwide (four BRIs are required for 512 kbps).
The channel is opened by dialling the number of the appropriate correspondent.
   
Transparent transmission comparable to the service
on a leased line
Once communication has been initiated between two inverse multiplexers, they are invisible to the protocol being carried. The resulting service is consequently comparable to a 512 kbps leased digital line.
   
Compatible BONDING The IM 512 uses the BONDING synchronization standard to "aggregate" ISDN channels. As a result it is compatible with most equivalent products on the market.
   
   
Compatible with most network equipment and videoconferencing codecs The IM 512 interfaces with the data terminal via a V11 or V35 link.
It is compatible with all network equipment fitted with this interface (routers, FRAD, TDM multiplexers, etc.).
It is also compatible with most videoconferencing codecs.
   
Flexible operations The multiplexer is simple to set up. In addition, the operator can consult a detailed log for trouble-shooting.
Calls can be made in a number of ways:
- Manual dialling using the keypad on the front panel or via a VT100 terminal,
- Command signal (DTR or C),
- Synchronous or asynchronous V25 bis commands,
- X21 commands.
   
Remote management Multiplexer settings can be changed from a remote workstation, with an ISDN connection, using IATERMINAL software.
