IMX-2 Inverse Multiplexer
IMX-2 is an inverse multiplexer that splits a data channel between a leased
line and an ISDN switched circuit connection depending on mode of
operation, line availability and traffic load. Typical applications for the IMX-2
include high speed leased line backup, Dynamic Bandwidth Allocation and
Bandwidth on Demand.
The
IMX-4T1/E1 Inverse Multiplexer aggregates the bandwidth from up
to four T1/E1 lines to create a logical channel from up to 5.888/7.680 Mbps.
It bridges the bandwidth gap between T1/E1 and T3/E3 by providing
increased bandwidth where services above T1/E1 are either not available or
are too expensive to use. The high transmission rates are provided for
applications such as router inter-networking. Two or four T1/E1 ports are
available and can be ordered with or without CSUs. The IMX-4E1 has
automatic rate fallback to lower speeds. If an T1/E1 line fails, the communi-
cation link remains open at a reduced speed. The IMX-4T1/E1 provides
immediate connection upon installation. DTE interfaces are available for:
V.35, V.36/RS-449, RS-530/RS-422, X.21 or HSSI. The data rate can be any
multiple of 1.472/1.920 Mbps to a total of 5.888/7.680 Mbps.

DXC Digital Inverse Multiplexer Module
DIM is a Digital Inverse Multiplexer module for the modular Digital Cross
Connect units. The DIM module, working in conjunction with dual-port DE1
or DT1 link modules (up to four modules per DIM), enables the DXC to
function as an inverse multiplexer. The DIM module is available with a
variety of serial port options and Ethernet bridge option. Up to 8 T1/E1
trunks can be inverse multiplexed and aggregated to a single user serial or
Ethernet port.

See pages 45 - 46 for ISDN
inverse multiplexing products.
The IMXi-4 Inverse Multiplexer is a user-friendly, easy-to-install, plug-
and-play unit which splits and transmits a high-speed single data channel of
up to 8.04 Mbps, over up to four E1/T1 or SHDSL links. IMXi-4 spans the
bandwidth gap between E1/T1 and E3/T3 services, providing increased
bandwidth where services higher than E1/T1 are either not available or too
expensive. IMXi-4 is a compact standalone unit. A rack mount adapter kit
enables installation of one or two standalone units, side by side in a 19" rack.
