RAD Data comm 4-Wire Symmetrical VDSL Modem ASM-60 - Manual (Page 20)

Chapter 1 Introduction ASM-60 Installation and Operation Manual
1-2 Overview
Features
ASM-60 utilizes the QAM VDSL technology to extend the range of data
transmission over 4-wire 24 AWG line up to 2.0 km (1.2 miles). ASM-60 operates
at the following data rates: 4.096 Mbps, 6.144 Mbps and 10.24 Mbps.
Table 1-1
lists typical ASM-60 ranges over 24 AWG STP Cat. 5 wire.
Table 1-1. Typical ASM-60 Ranges
Data Rate 24 AWG
(Mbps) km miles
4.096 2.0 1.2
6.144 2.0 1.2
10.24 1.8 1.1
DTE Interface
The ASM-60 DTE interface supports the following interfaces:
• HSSI
• IR-ETH module with built-in Ethernet bridge
• IR-ETH/QH module with built-in Fast Ethernet bridge and VLAN support
• IR-IP module with built-in IP router.
Management
Setup, control, monitoring of status and diagnostics can be performed using an
ASCII terminal connected to the ASM-60 async DCE control port.
Test Capabilities
ASM-60 performs an extensive self-test at start-up. During the self-test, ASM-60
checks its CPU, internal framer, DTE and interfaces and power supplies. The
self-test results are displayed on the supervisory terminal.
Real Time Alarms
Real time alarms provide real time information on system status indicating loss of
synchronization on line A and line B, DCD status etc.
ASM-60 also features a log file that stores all alarms and events that occurred in the
unit. These alarms can be displayed and cleared.
Statistics Collection
ASM-60 stores the VDSL statistics for the line performance monitoring.
