Product Summary

The ASMi-52 SHDSL modem transmits E1, T1, Ethernet or serial data, and multiplexes combined streams of E1, Ethernet or serial at various data rates over a range of up to 10 km (6.2 miles). The ASMi-52L SHDSL model is optimized for applications requiring a single service. The ASMi-52 SHSDL modem transmits at data rates up to 2.3 Mbps over 2-wire and 4.6 Mbps over 4-wire. The ASMi-52 and ASMi-52L SHDSL modems incorporate TC-PAM technology for extending transmission range, offering carriers and enterprises a cost-effective solution for data transmission at higher data rates over larger distances in the Last Mile. Typical applications include, municipalities, utilities, corporate connectivity, and cellular backhaul.

Benefits

• Operates over 2-wire and 4-wire lines, enabling service over any copper infrastructure• Compatible with SHDSL repeaters, enabling long distance applications• Utilizes TC-PAM line coding for extending the operation range to 10 km (6.2 miles) over 24 AWG without repeaters• Provides extensive diagnostics, including loopbacks, SHDSL and E1 performance monitoring• Supports dry contact applications such as SCADA• Reliable performance over poor quality or noisy lines• Automatic configuration allows plug-and-play installation

Further Product Information

The ASMi-52 and ASMi-52L modems 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 ASMi-52 modem and multiplexer model is equipped with one or two user ports. It can transmit combinations of V.35/X.21/RS-530 data, 10/100BaseT LAN, and E1 traffic over a single SHDSL link at a maximum data rate of 2.3 Mbps.

ASMi-52L version

The economically priced ASMi-52L model is offered for applications requiring a single service, available with a port for E1,V.35, X.21, ,Ethernet or four 10/100BaseT ports with an integral switch. 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, reaching a maximum of 10 km. for 64 kbps data. All models are compatible with 2/4-wire repeaters, such as RAD's S-RPT, for supporting even longer-range applications. The products comply with ITU-TG.991.2 and ETSI 101524 standards for SHDSL. They can also work opposite RAD's 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 supports the SHDSL standard. The ASMi-52 is available as a standalone unit or as a card for the LRS-24 19-inch rack with central SNMP management. The ASMi-52 is also available in a half-19-inch metal enclosure or rugged metal enclosure designed for easy installation on standard cabinet rail mounts that meet the EN 50121-4 industry standard (also for ASMi-52L with four Ethernet ports).

Management options

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)
