The device can extend the service range up to 2.6 km (1.825 miles) for each 5.7 Mbps pair at 26 AWG. The ASMi-53 is part of the AXCESS+ portfolio of multiservice access and First Mile solutions, offering an ideal solution for carriers, service providers and mobile operators, as well as corporate, utilities and transportation companies looking for economical delivery of voice and broadband data traffic in point-topoint or hub and spoke communications.
Featuring a built-in Ethernet switch, the ASMi-53 SHDSL.bis modem includes a 10/100BaseT user port and supports VLANaware and VLAN-unaware bridging. VLAN stacking (Q-in-Q) and stripping functionalities enable transparent traffic delivery over packet switched networks with optimal efficiency. QoS (quality of service) levels are defined according to VLAN priority (802.1p), DSCP, or per port, offering users flexibility in differentiating traffic handling depending on application requirements. Up to four priority queues are supported using Strict Priority (SP) scheduling.
Fault propagation enables the unit to shut down the Ethernet user port when an SHDSL line failure is detected and to switch traffic to an alternate route. EFM bonding capabilities ensure that a failure or addition of a link does not drop the traffic being transmitted over the other wires in the group. Capacity is also maintained when a new link is added at a lower rate during Ethernet transmission.
The ASMi-53 can be managed inband via the SHDSL channel (Ethernet over copper) for configuration, monitoring and diagnostics. Some management functions can be performed via a local RS-232 terminal.
