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.
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.
