The ASMi-54 SHDSL.bis modem is a cost-effective, dedicated managed device for offering mid-band Ethernet connectivity based on multi-pair bonding technology. Using TC-PAM 16 or TC-PAM 32 line coding SHDSL.bis technology, the ASMi-54 G.SHDSL.bis modem can operate in full duplex mode over 2-wire, 4-wire or 8-wire lines, achieving variable data rates up to 5.7 Mbps over 2-wire, 11.4 Mbps over 4-wire, and up to 22.8 Mbps over 8-wire.
The ASMi-54 SHDSL.bis modem supports point-to-point Ethernet connection of up to 22.8 Mbps over 8 wires (4 pairs) using bonding of multiple copper pairs.
Multi-pair bonding ensures that a failure or addition of a link does not drop the traffic being transmitted over the other wires in the group nor is the capacity of the group decreased when a new link is added at a lower rate.
Monitoring, control and diagnostics of local and remote units are available via a supervisory port.
The unit supports up to four 10/100BaseT ports with half/full-duplex auto-negotiation and flow control. Fault propagation enables the unit to shut down the Ethernet user port when an SHDSL line failure is detected.
For LAN-to-LAN connectivity, the modem supports a built-in 10/100BaseT switch and VLAN transparent support.
The ASMi-54 SHDSL.bis modem supports both Quality of Service (QoS) priority queues according to 802.1p and IP Precedence, enabling users to define different levels of QoS according to the application requirements.
The ASMi-54 SHDSL.bis modem can be ordered with a plastic box (2W, 4W) or a metal enclosure (8W).
The management connection to the standalone unit is via:
-
Virtual terminal, in-band and out-of-band Ethernet port
-
Local terminal, Telnet server, SNMP, Web server (ConfiguRAD)
-
Dedicated VLAN for management
Up to eight SHDSL repeaters can be installed in line to increase the operation range of E1- and Ethernet-based modems. RAD offers three types of repeaters: 2-wire, 4-wire indoor and 4-wire outdoor. All three types support SHDSL.bis technology and can work opposite ASMi-54 over 2-wire and 4-wire lines.
ASMi-54 is interoperable with RAD’s LRS-102 high-density SNMP managed transparent rack, which operates over copper or fiber. The LRS-102 chassis has slots to accommodate up to 12 individual ASMi-54C modules, transmitting up to 96 E1 links over copper or up to 24 Ethernet ports that can operate opposite up to 96 modems.
Each ASMi-54C module features two Ethernet ports for transmission over 16 wire SHDSL lines and can work opposite remote devices in the following combinations, depending on the application requirements:
-
2 x 8-wire ASMi-54 standalone modems
-
4 x 4-wire ASMi-54 standalone modems
-
8 x 2-wire ASMi-54 standalone modems
