• The AMC-M/10BT/B modules require the modules of the same type installed at
the local and remote sites of the application (AMC-101 only).
• 135m range of the AMC-M/CX/BNC/155 and AMC-M/CX/DIN/155 is attainable
when using RG-59 B/U (at 78 MHz, in accordance with the square root of
frequency law).
Controls
AMC-101 includes a rate selector for retimed modules (51, 100, 155 Mbps). For
transparent modules, the rate selector is set to the OTHER position.
If the rate selector is set to OTHER, retimed modules operate in transparent mode.
Diagnostics
AMC-101 supports activation of simultaneous loopbacks towards the user and
network sides. The loopbacks are activated via a front panel WRAP pushbutton.
Alarm Relay
AMC-101 includes a D-type 9-pin dry contact female connector, which serves for
relaying major and minor alarms.
Compliance
AMC-101 operation complies with ATM Forum and ITU-T G.957 and G.958
specifications.
