IMX-2

Inverse Multiplexer and Leased Line Backup Unit

• ISDN backup of leased lines and dynamic bandwidth allocation
• Provides bandwidth-on-demand (smart terminal adapter)
• Can operate over a combination of one or two switched B-channels and one leased line
• Integrated terminal adapter supports Euro-ISDN, 5ESS, National ISDN (Ni1), DMS-100 and NTT
• Supports BONDING protocol specification (modes 1, 2 and 3)
• Configuration via front panel or control port

The IMX-2 is an inverse multiplexer that splits incoming data between a leased line and an ISDN link, according to mode of operation, line availability and traffic load.Typical applications for the IMX-2 include leased line backup, dynamic bandwidth allocation and bandwidth-on-demand.The IMX-2 offers a large choice of interfaces on the network side as well as the data ports. It connects to basic rate ISDN (BRI) switched digital service and supports S and U interfaces, as well as S leased line interface (S0). It also supports one dedicated circuit (leased line) with all popular interfaces: V.35, V.36/RS-422, RS-530 or X.21.For applications such as videoconferencing that require switched connections, the IMX-2 can act as a smart terminal adapter and call up to two B channels to provide 128 kbps aggregate bandwidth.The IMX-2 provides command-driven software control of configuration, diagnostics and alarms via a terminal connected to the supervisory port. SNMP over SLIP support is also available.
