Model ASM-61
available for 2-Wire applications
Using symmetrical VDSL
technology, ASM-60 operates at rates up to 10 Mbps over 4-wire lines. The
ASM-60 extends the range of digital equipment up to 2 km (1.2 miles) over 24
AWG (0.5 mm) 4-wire copper cable. This eliminates the need for optical cable
in the Last Mile (Local Loop) or in the campus network environment.
The ASM-60 compensates for line impairments and mixed cabling by using
advanced equalization, adaptive filtering, echo cancellation technology and
QAM line coding.
Setup, control and monitoring of status and diagnostic information can be
performed using an ASCII terminal connected to the async control port.
The ASM-60 is available as a standalone unit which can be mounted in a
standard 19" rack using special hardware. Two ASM-60 units can be mounted
side-by-side.
The ASM-61 (not shown) does 2-wire
lines.
