SHDSL Ethernet Modem & Mux

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.

• 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

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.

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.

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).

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)
