High flexibility with daisy-chain and ring

topologies

The ASMi-54 supports drop-and-insert (daisy-

chain) applications, enabling bi-directional delivery

of high rate Ethernet traffic over DSL lines by

connecting multiple locations in a multidrop

network.

Alternatively, the device can be deployed in ring

architecture, featuring spanning tree protocol

(STP) support to ensure high availability and

service resiliency in the event of link failure. The

ASMi-54L meets EN-50121-4 industry standard for

high electromagnetic reliability.

Card version for modem rack

The ASMi-54C is a card version for mounting in a

central LRS-102/Megaplex-4100 rack. The

ASMi-54C SHDSL.bis module multiplexes E1 and

Ethernet over one, two or four pairs of SHDSL.bis

copper lines. It is installed in an LRS-102 chassis

which can contain up to 12 card modules, each

with eight E1 interfaces and/or two 10/100BaseT

Ethernet ports, to provide a cost-effective central-

site solution for up to eight ASMi-54 standalone

units over 2-wire or any other combination up to

8-wire. Alternatively, the ASMi-54C can work

opposite remote ASMi-52/52L 2/4-wire SHDSL

modems in applications requiring lower rates

over SHDSL lines. Management traffic for all

remote units is delivered via one of the

ASMi-54C’s Fast Ethernet ports, using a

dedicated management VLAN. By supporting

both E1 and Ethernet access at the central

office (CO), the ASMi-54C modules enable an

easy migration from TDM to IP networks.

Management options

The ASMi-54 standalone units support the

following management connections for

configuration, monitoring and diagnostics:

• Local RS-232 terminal

• Telnet server, SNMP (ver.1)

• RADview-EMS Web server

• Network links for Inband management with a

dedicated VLAN
