ASMi-53 SHDSL.bis CPE Modem
Key features ASMi-53 SHDSL.bis CPE Modem from RAD include:
ASMi-53 is a cost-effective, dedicated, managed SHDSL.bis modem that extends the range of high-speed services over existing copper pairs. The modem is used for Ethernet, E1 and V.35 service extension at rates of up to 11.4 Mbps over 4-wire lines using bonding technology.
The modem features an Ethernet, E1 or V.35 user interface. ASMi-53/Type1 can be ordered with:
RAD ASMi-53 Market Segments and Applications
ASMi-53 targets the following market segments:
Interoperability of the ASMi-53
ASMi-53 is interoperable with the following CO devices:
SHDSL with ASMi-53
ASMi-53 features one Ethernet 10/100BaseT port with half/full-duplex, autonegotiation and flow control. LAN is connected to network by bridging. The Ethernet port operates in a VLAN unaware mode (802.1d unaware). In this mode, all the Ethernet traffic reaching the port is forwarded to the network port and vice versa.
EFM Bonding When using Ethernet service, EFM (Ethernet Fist Mile) bonding is applied. EFM bonding allows multiple pairs to be used as a single, high capacity link, providing more bandwidth over the existing copper infrastructure. EFM bonding shares Ethernet payload between the connected SHDSL lines, ensuring user traffic reliability in case of one pair failure.
Traffic Management/QoS on the ASMi-53
Traffic Management/QoS The DSCP priority schemes, and 802.1p priority classification allow users to define different QoS levels according to application requirements.The modem implements the IEEE's 802.1q standard to provide four levels of prioritization, enabling carriers to offer differentiated Ethernet services. Management traffic can be transferred via a separate VLAN, ensuring transparency of the customer traffic and enhanced management security. The user can activate or deactivate the priority mechanism. The priority can be configured and mapped to one of four priority queues. Ethernet port ingress and egress data rates can be limited.
