Introduction
1.1 Overview
ASMi-52CQ is a card containing four independent 2-wire Synchronous High Bit
Rate Digital Subscriber Line (SHDSL) modems operating in full-duplex over 2-wire
lines. It offers a cost effective solution delivering digital data to customer
premises over existing copper cables. ASMi-52CQ handles multiples data rates in
the range of 64–2304 kbps. The modem card includes four modems, supporting
RS-530, V.35, X.21 and E1/T1 DTE interfaces. ASMi-52CQ uses TC-PAM coding and
complies with the ITU-T G.991.2 requirements.
ASMi-52CQ is housed within RAD's compact 12-slot LRS-24 Access Rack, enabling
up to 48 modems in one rack and drastically reducing port price. LRS-24 is
managed by the RADview SNMP management tool, Telnet or an ASCII terminal.
A card can be removed and re-inserted without powering down the system and
without affecting operation of other modules in the system.
