ASM-60
4-Wire Symmetrical VDSL-Based Modem• ASM-60 is managed via an ASCII

terminal connected to thefront-panel supervisory port. The
embedded menu-driven software
allows to perform the following
activities:
Data rate selection
Modem's status display
VDSL statistics collection
Real time alert of fault
conditions.

FEATURES• 4-wire VDSL-based modem,
enabling symmetrical full
duplex data transmission forranges of up to 2.0 km(1.2 miles)• Supports data rates of up to10.24 Mbps (depending onapplication)• Employs VDSL QAM line
coding for better bandwidthutilization• Supports Ethernet and highspeed DTE interfaces• Setup, control andmonitoring via an ASCII
terminal connected to thesupervisory port
• Diagnostics include LED
testing and VDSL
performance monitoring

DESCRIPTION• ASM-60, a VDSL-based modem,

operates in full duplex over 4-wire
19–26 AWG lines.

• Transmitting data at 4.096 Mbps,
6.144 Mbps or 10.24 Mbps,
ASM-60 eliminates the need forfiber optic cables in the last mile(local loop) or campus network
environment.

• ASM-60 uses the VDSL QAM

technology to improve thebandwidth utilization and ensure
efficient transmission, even overpoor quality lines.

• Two versions of the modem areavailable:
ASM-60/CO, for installation at
central officeASM-60/CPE, for installation atcustomer premises.

• DTE interfaces supported:
HSSI
Ethernet bridge (IR-ETH)
10/100BaseT bridge with VLAN
support (IR-ETH/QH)
IP router (IR-IP).
