Key features ASMi-53 SHDSL.bis CPE Modem from RAD include:

  • Managed SHDSL.bis modem transmitting full-duplex at data rates of up to 5.7 Mbps over 2-wire, and 11.4 Mbps over 2/4-wire lines
  • Dual Bearer mode enabling E1 or V.35 service combination with Ethernet
  • High Ethernet performance including QoS and EFM bonding
  • Operating as STU-C (CO) or STU-R (CPE)
  • Full interoperability with Megaplex-4, LRS-102 (ASMi-54C and ASMi-54C/N modules), and third-party equipment
  • Remote power feeding
  • ASMi-53 overview

    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:

  • Ethernet interface
  • Ethernet and E1 interfaces
  • Ethernet and V.35 interfaces
  • ASMi-53/Type2 enables E1 and Ethernet or E1 and V.35 services combination and can be remotely powered by PFH-4 or by the MPF power feed unit, connected to Megaplex-4

    RAD ASMi-53 provides Fast Ethernet and TDM services over SHDSL

    RAD ASMi-53 Market Segments and Applications

    ASMi-53 targets the following market segments:

  • Service providers
  • Corporate, utilities and transportation companies looking for economical delivery of voice and broadband data traffic.

  • ASMi-53 operates as a CO (Central Office) device or CPE (Customer Premises Equipment) in point-to-point applications ( Figure 1 ).

    Interoperability of the ASMi-53

    ASMi-53 is interoperable with the following CO devices:

  • Megaplex-4 or LRS-102 chassis, equipped with ASMi-54C or ASMi-54C/N modules ( Figure 2 )
  • Third-party DSLAMs ( Figure 3 ).
  • SHDSL with ASMi-53

    The RAD ASMi-53 modem employs TPS-TC framing 64/65o for EFM (IEEE802.3) and HDLC (G.991.2) on the SHDSL link.

    In CPE mode, ASMi-53 can be remotely managed by Megaplex-4 or LRS-102 through EOC (Embedded Operations Channel), VT (Virtual Terminal) or Telnet.

    ASMi-53 Ethernet

    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 capabilites of RAD ASMi-53 SHDSL.bis CPE Modem

    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.

    ASMi-53 TDM

    TDM ASMi-53 transports:

  • Framed and unframed E1 traffic
  • V.35 serial data stream with the maximum data rate of 2.048 Mbps
  • E1 and V.35 traffic with the maximum aggregate rate of 4 Mbps.
  • Note: TDM traffic is supported in the HDLC mode only.

    TIMING AND SYNCHRONIZATION ON THE ASMi-53

    In CO mode, ASMi-53 generates an internal synchronization signal or receives it from the E1 channel.

    In CPE mode, ASMi-53 receives the synchronization signal from the CO unit

    RAD ASMi-53 MANAGEMENT AND SECURITY

    ASMi-53 can be managed :

  • Locally, by an RS-232 terminal
  • Inband, via EOC (in CPE mode only)
  • By virtual terminal (in CPE mode only)
  • Via Telnet (in CPE mode via Megaplex only).
  • RAD ASMi-53 MONITORING AND DIAGNOSTICS

    ASMi-53 features an alarm system, physical layer performance monitoring (SHDSL, E1 and ETH statistics collection), and standard loopback diagnostics.


    The fault propagation functionality enables the unit to shut down the Ethernet port when an SHDSL line failure is detected.

    Diagnostic loopbacks and internal BERT are supported.
