Regulatory Information
FCC-15 User Information
This equipment has been tested and found to comply with the limits of the Class A digital device,
pursuant to Part 15 of the FCC rules. These limits are desi gned to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses and can radiate radio frequency ene rgy and, if not installed and used i n accordance
with the instruction manual, may cause harmful interference to the radio communications. Operation
of this equipment in a residential area is likely to cause harmful interference in which case the us er will
be required to correct the interference at his own expense.
Warning per EN 55022
This is a Class A product. In a domestic environment, this product may cause radio interference, in
which case the user may be required to take adequate measures.

The AMC-101, a Universal Converter and Repeater, provides retimed or
transparent conversion of optical and electrical signals for ATM, FDDI, Fast
Ethernet and other protocols at data rates up to 155 Mbps. The modularity
of the AMC-101 interfaces enables field-changeable conversion between
any two media.
Transparent modules provide cost-effective media conversion without
reclocking. Retimed modules provide media conversion with reclocking,
which enables the AMC-101 to be used as a repeater. These modules can
also be set for transparent operation.
AMC-101 is supplied as a standalone unit. Special hardware for mounting
either a single unit or two units side-by-side in a 19" rack can be ordered
separately.
Retimed Modules
Transparent
Modules
The AMC-101 provides retimed media conversion for the following ATM
interfaces:
• TAXI (100 Mbps)
• STM-1
• STS-3c
• STS-1 over optical and electrical interfaces.
Retimed conversion is also available for FDDI and Fast Ethernet between
single mode and multimode fiber, and for extending FDDI UTP
connections over fiber. The retimed modules provide rate selection for 51,
100 or 155 Mbps. When set to one of these rates, the retimed module
regenerates and reclocks the incoming signal and acts as an ATM or FDDI
repeater. When the switch is set to "OTHER", the modules regenerate the
signal without reclocking as transparent modules do.
The AMC-101 provides transparent conversion for any two-level optical
protocol. Transparent modules are recommended for short distances and
for all fiber and copper applications at less than 100 Mbps.
A special WRAP button activates loopbacks at the two interfaces. This can
be used for test purposes or for special applications as explained later.

1-2Features
Multiple connector types are available for both electrical and optical
interfaces.
A single AMC-101 in WRAP mode can be used for double conversion
between single mode and multimode fiber for a dual attached FDDI station
or concentrator (see Figure 1-3).
Figure 1-3 WRAP: Dual Single Mode (SM) to Multimode (MM) Conversion
ATM Switch
A single AMC-101 equipped with a single interface in WRAP mode can be
used for conversion between single mode and multimode fiber
(see Figure 1-4).
The FDDI applies scrambling to data when operating over UTP, but not
doing so when operating over fiber. Because of this, AMC-101 can only
work in pairs for extending FDDI connections over fiber (see Figure 1-5).
