Features
Each Inverse Multiplexer system requires at least two different
modules: the IMUX 2160 and the QUAD 2164. When more than 4 E1
or T1 circuits are supported, two of the QUAD 2164 modules are
used.
System The IMUX 2160 interfaces to data terminal equipment (DTE), and
the QUAD 2164 accesses a T1 or E1 network. These modules form a
single system for distributing data from a high-speed source over
multiple T1s or E1s for a maximum of 12 Mbit/s over 8 T1s or 16
Mbit/s over 8 E1s.

The IMUX 2160 rear connector module is available with a V.35, EIA
530, EIA 530A, RS-449 or HSSI data port. The V.35, EIA 530, EIA
530A and RS-449 interfaces support up to 4 T1s or 3 E1s for a data
rate slightly over 6 Mbit/s, whereas the HSSI interface supports up
to 8 T1s at a data rate of 12 Mbps or 8 E1s at a data rate of 16
Mbit/s.
The QUAD 2164 rear connector module determines whether a given
QUAD 2164 module will handle E1 or T1 lines.
The Inverse Multiplexer system can operate with or without an NCM
2000 (Node Controller Module). Simple point-to-point applications
can operate in standalone mode. With multiple applications at an
AS2000 node, the Inverse multiplexer is managed using the NCM
2000.
The QUAD/IMUX provides the following features:
T1 Interfaces The DS-1 (long-haul) and DSX-1 (short-haul)
QUAD interfaces are fully compatible with
industry-standard framing and line coding
options (ESF, SF, AMI, B8ZS).
E1 Interfaces The 75 ohm and 120 ohm E1 QUAD interfaces
support HDB3 line coding.
Data Rates The Inverse Multiplexer has selectable data
rates: nx1.336 Mbit/s (in 56K mode), nx1.528
Mbit/s (in 64K T1 mode), or nx1.976 Mbit/s (E1
mode), where n=1 to 8.
