Further Product Information
The ASMi-52 SHDSL modem and ASMi-52L SHDSL modem use TC PAM-16 line coding SHDSL technology to extend the range of digital interfaces. These devices offer longer distances and variable data rates up to 2.3 Mbps over 2-wire and 4.6 Mbps over 4-wire.

ASMi-52 multiplexer version

The high-end ASMi-52 SHDSL modem model is available with a multiplexer capability, including two user ports. It can transmit combinations of V.35/X.21/RS-530 data, 10/100BaseT LAN and E1 traffic together over a single SHDSL link at a maximum data rate of 2.3 Mbps. The attractively priced ASMi-52L model is offered for applications that require only a single user port. 

The ASMi SHDSL modems extend the range of 2 Mbps data transmission up to 4 km (2.5 miles) over 2-wire cable and even farther over 4-wire cable. They support E1 and T1, V.35, X.21 and RS-530 data, Ethernet bridge, and IP router user interface options. The ASMi-52L SHDSL modem is also available with optional four 10/100BaseT user ports with an integral switch. All models are compatible with 2/4-wire repeaters, such as S-RPT, for supporting even longer-range applications.

They also work opposite LRS-52 SHDSL modem rack, the LRS-24 modem rack, DXC, and Megaplex SHDSL modules. Monitoring, control and diagnostics of local and remote units are available via a supervisory port. Standards compliance enables the ASMi modems to work opposite third-party TDM equipment that support the SHDSL standard.

The ASMi-52 SHDSL modem is available as a standalone unit or as a card for the LRS-24 19-inch rack with central SNMP management.

The management connection to the standalone unit is via: 

• V.24/RS-232 port using SLIP protocol 

• Out-of-band Ethernet port (ASMi-52 only) 

• Dedicated timeslot using E1/T1 port (ASMi-52 only)

Easy Config accessory
Easy Config is a hand-held battery powered configuration accessory that enables the user to configure the ASMi-52 SHDSL modem from the RS-232 port without requiring a laptop or computer terminal. The ASMi-52 SHDSL modem configuration parameters appear on the Easy Config screen for instant viewing.
