The ASMi-52L SHDSL modem uses TC PAM-16 line coding SHDSL technology to extend the range of digital interfaces. The ASMi-52L SHDSL modem offers longer distances and variable data rates up to 2.3 Mbps over 2-wire and 4.6 Mbps over 4-wire.

Cost-effective Ethernet extension

The attractively priced ASMi-52L SHDSL modem has been optimized for applications requiring only a single user port. The modem offers a variety of interfaces: V.35, X.21, E1, 10/100BaseT bridge with VLAN support or four-port 10/100BaseT bridge with VLAN support).

The ASMi-52L SHDSL modem extends the range of 2 Mbps data transmission more than 4 km over 2-wire or 4-wire cable. The maximum transmission rage is 10 km (6.2 miles) over 24 AWG.

The ASMi-52L is compatible with 2/4-wire repeaters, such as RAD’s S-RPT, for supporting even longer-range applications.

It also works opposite RAD’s LRS-24 modem rackDXC, and Megaplex SHDSL modules. Monitoring, control and diagnostics of local and remote units are available via a supervisory port. Standards compliance enables the ASMi-52 modem to work opposite third-party TDM equipment that supports the SHDSL standard.

The ASMi-52L SHDSL modem is available as a standalone unit or as a card for the LRS-24 19-inch rack with central SNMP management.
It is also available in a rugged metal enclosure designed for easy installation on cabinet rail mounts that meet the EN 50121-4 industry standard.

The management connection to the standalone unit is operated via the V.24/RS-232 port using SLIP protocol.
