codirectional

•

Optional built-in router

•

Works opposite Megaplex and DXC IDSL

cards

The ASMi-31 manageable IDSL modem operates

full duplex over twisted pair, 2-wire unconditioned

lines. It has a transmission range of up to 8 km

(5 miles) over 24 AWG cable and operates at

user-selectable rates from 1.2 kbps to 128 kbps.

The ASMi-31 can also work opposite the DXC

with D8U card, or opposite the Megaplex with

the U interface module.

SNMP management is available for the cards

inside the rack via the management channel

and for the customer premises standalone units.

The RADview SNMP application running on an

HP OpenView UNIX or PC platform supports

management of the ASMi-31 and other RAD

modems.

The ASMi-31 is an IDSL modem based on 2B1Q

technology, which is common to both ISDN and

DSL technologies. This line code enables

efficient transmission over poor quality lines.

Transmit timing is provided internally or

recovered externally from the received signal. It

can also be derived externally from the digital

interface, enabling tail-end applications.

ASM-61

2-Wire Symmetrical VDSL-Based Modem

A complete solution for high speed services over

existing copper lines, the ASM-61 provides full

duplex, symmetrical 10 Mbps Ethernet traffic

over 2-wire 24 AWG (0.5 mm) copper cable, for

distances of up to 1 km (0.6 miles).

The ASM-61 extends the range of internal LANs

using VDSL technology, based on ETSI QAM line

coding requirements for the physical medium.

The ASM-61 compensates for line impairments

and mixed cabling by using advanced

equalization, adaptive filtering and echo

cancellation technology.

An internal clock is available. In this mode, the

internal clock generator provides the clock for

the digital interface and the line.

The ASM-61 is powered by AC voltage. It is

available as a standalone unit that can be

mounted in a standard 19-inch rack using

special hardware.
