Introduction
1.1  General
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.

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).

Procedure
Power
Front and Rear 
Panel Clearance
Inspect the equipment container before unpacking. Note and report 
evidence of damage immediately.
•    Place the container on a clean flat surface. Cut all s traps and open or 
remove top.
•   Remove the unit carefully and place it securely on a clean surface. 
•   Remove all packing material. 
•   Inspect the unit for damage. Report any damage immediately. 
2.2  Site Requirements
AMC-101 is powered by 100 to 240 VAC or -48 VDC. 
The unit should be installed within 1.5m (5 ft) of an easily accessible
grounded AC outlet capable of supplying 230 V (115 V). 
Allow at least 90 cm (36 in) of clearance at the front of the unit for operator
access. Allow at least 10 cm (4 in) clearance at the rear of the unit for power 
cord connection.
Ambient 
Requirements
The ambient operating temperature of AMC-101 should be 0-40oC 
(32-122
o
F) at a relative humidity of up to 90%, non-condensing.
Site Requirements  2-1

Installation of a 
Single Unit
Figure 2-2 AMC-101 Rear Panel DC Version
Rack adapter components for installing a single unit include one short 
bracket and one long bracket. Each bracket is fastened to the side walls of 
the unit by two screws (with flat washers) which are inserted into the two 
front holes on the side wall (The unit is supplied with nuts already in place 
on the inner side wall). Note that the short bracket fastens to the left side of 
the unit, and the long bracket to the right side of the unit (see Figure 2-3 ).
Once the brackets are fastened to the side walls, the unit is ready for 
installation in the 19" rack. Place the unit in the rack and fasten the brackets 
to the side rails of the rack by means of the two screws situated on each side 
(not included in the kit).

Installation of 
Two Units
Rack adapter components for installing two units include two long side rails 
(one for each unit) which slide one into the other fastening the two units 
together, and two short side brackets which hold the two units in the 
19'' rack (see Figure 2-4 ).
Figure 2-4 Installation of Two Units (a)
To install two units follow these instructions:
1.  Fasten one lon 
the other unit) usin 
rails must be attached in o
 side rail to each unit (right side to one unit, left side to
 the four screws and flat washers supplied. The side
osing fashion, the narrow flange of the first
rail opposite the wide flange of the second rail.
2.  Attach one short bracket o
osite the side rail on each unit using the
four screws and flat washers supplied.
3.  Slide the side rail of one unit into the side rail of the other unit, fastenin 
the two units together (see Figure 2-5). 
4.  Secure the su
lied plastic caps to the ends of the rails, to prevent the
units moving and to protect the rail ends.
5. Place the assembled units in the rack and fasten the brackets to the side 
rails of the rack, by means of the four screws situated on each side 
(not included in the kit).

2.3  Cable Connections
AC power should be supplied to AMC-101 through a 1.5m (5 ft) standard 
power cord terminated by a grounded 3-wire plug.
When applying AC power, first connect the plug of the AC cable to the 
power connector on the rear panel of AMC-101 and then to the mains 
outlet.
Interrupting of the protective (grounding) conductor (inside or outside 
the instrument) or disconnecting the protective earth terminal can make 
this instrument dangerous. Intentional interruption of the grounding 
conductor is prohibited.

In order to protect the AMC-1 from electrostatic discharge (ESD), use a DC 
adapter where the (-) DC pole is connected to the protective earth.
3.3  Dry Contact Circuit and Connector for Alarms
A dry circuit with a 9-pin D-type connector on the rear panel, has been 
added to the unit to signal minor and major alarms. The dry contact ci rcuit 
is used to signal the following alarms:
Alarm type  Description
RED ALARM  Power Failure (DC voltage on board) 
YELLOW ALARM  Signal Detect Failure (to any of the unit modules)
CONFIG ALARM  Improper Configuration (incompatible modules
and/or data rates selected)
Three pins are dedicated for each alarm: Common (COM), OK and FAIL. 
The COM pin is the input for each alarm. The user can drive the COM pin 
with any signal (0 to 5v). If the signal is received OK, the COM pin is 
connected to its corresponding OK pin; If there is a failure, the COM pin is 
connected to its c orresponding FAIL pin. See Table 3-4  and Figure 3-3  for 
the connector pin assignments.

Alarm Type  COM  OK  FAIL
RED  9  4  5 
YELLOW  3  8  7 
CONFIG  6  2  1

Chapter 3 - Operation  AMC-101  Installation & Operation Manual
Example:
For the RED ALARM the common input (COM) pin is 9. If there is no power 
failure, it connects to pin 4 (OK). If there is a failure, pin 9 connects to pin 5 
(FAIL).
3.4  Turning on the AMC-101
Connect the AC cable of AMC-101 to the mains outlet. The POWER 
indicator on the front panel should light up.

3.5  Normal Operation
Once powered on, the POWER indicator should light up and the FLT should 
be turned off. If the FLT indicator blinks, a configuration error exists: the 
combination of the card types and the selected data rate is illegal.
Each AMC-101 module contains a SIG indicator. If the SIG indicator is 
turned off; no signal is received by the module. If the SIG is turned on; a 
signal is received by the module, and if the re-timing option is in use, the 
PLL is synchronized to the receive signal. If the SIG blinks, a signal is 
received by the module but the PLL is out of sync.
A special circuitry can be configured to transmit idle signal in case of not 
receiving any signal from the other side. This option is enabled by the idle 
jumper (JP-6) and can be used for power measurements in case of absence 
of "real" data.
The WRAP function can be locally activated at any time and causes the 
signal received by the module to be transmitted by the same module. If the 
module features retiming, the looped back signal is retimed and re-clocked.

3.6  Turning off the AMC-101
Disconnect the AMC-101 AC cable from the mains outlet.
3.7  Troubleshooting Procedures
Check the power cord connection on the back of the unit and at the mains 
outlet.
•    Verify power availability at the mains outlet.
Ensure that the plugged-in modules are compatible with the protocol used 
(media, data rate).
Ensure that the FLT LED is off. (If the LED blinks, a configuration error exists: 
the combination of the module types and the selected data rate is illegal).
Verify that the SIG LED is on and fixed. If the LED is off, no signal is being 
received by the module. If the LED is blinking, the module PLL is out of 
sync.
Use the WRAP option to localize the problematic segment.
