Chapter 1 Introduction 1.1 Overview This manual describes the technical characteristics, applications, installation and operation of the ASMi-54C SHDSL.bis I/O modules for the LRS-102 high-density SNMP managed modem rack. ASMi-54C modules are primarily intended to operate in a link with the ASMi-54 G.SHDSL.
Chapter 1 Introduction Note Installation and Operation Manual ASMi-54C modules can also be used to interconnect different LRS-102 units by means of SHDSL links. In this case, one ASMi-54C module must be configured to operate in the STU-C (central) mode, and the other ASMi-54C module(s) must be configured to operate in the STU-R (remote) mode. The traffic handling capabilities are similar to what is available with ASMi-54 standalone modems.
Installation and Operation Manual Chapter 1 Introduction The type of SHDSL interfaces provided by the module: central (STU-C: SHDSL terminal unit – CO) or remote (STU-R: SHDSL terminal unit – remote), as well as the transport bandwidth, are selected by software, and the module handles all the signal processing, framing and signaling processing tasks necessary for SHDSL.bis interoperability. ASMi-54C modules can be configured by the user to operate either in accordance with ITU-T Rec. G.991.
Chapter 1 Introduction Installation and Operation Manual As mentioned above, PAF can be used to bond several SHDSL lines, where each line can operate at a different rate. Bonding is possible only for lines handled by the same SHDSL section (either the section handling ports 1 to 4, or ports 5 to 8). A significant advantage of bonding per IEEE 802.3-2005 is that a failure of a SHDSL line does not drop the traffic being transmitted over the other wires in the bonded group.
Installation and Operation Manual Note Chapter 1 Introduction When only up to 8 ASMi-54C cards are planned for the chassis operation, a separate low-consumption power supply can be ordered from RAD (see ASMi-54C Data Sheet). The total Ethernet traffic handling capacity of each ASMi-54C depends on the SHDSL line rates. The maximum is always 2 × 22.8 Mbps each (approx. 45 Mbps), irrespective of the number of pairs used for SHDSL transmission.
Chapter 1 Introduction Installation and Operation Manual 1.2 Physical Description ASMi-54C modules occupy one I/O slot in the LRS-102 chassis. Typical panels are shown in Figure 1-2. ASMi-54C ASMi-54C S H D S L . b i s S H D S L . b i s Figure 1-2.

Chapter 1 Introduction • Installation and Operation Manual Ethernet subsystem, including the following functions: Main Ethernet switch Ethernet switch for access to the SHDSL subsystem External Ethernet port interfaces (transceivers) • Timing subsystem, including the internal timing generator • Local management subsystem.
Installation and Operation Manual Chapter 1 Introduction In general, the line rate is determined by the number of payload timeslots that need to be transmitted over the line served by the corresponding modem, which is user-selectable from a minimum of 3 timeslots to a maximum of 89 timeslots. Note If the number of timeslots routed to the corresponding port is lower than the maximum rate, any unused timeslots in the SHDSL signal frame is filled with the idle timeslot code.
Chapter 1 Introduction Installation and Operation Manual Ethernet Traffic Processor Each Ethernet traffic processor provides four independently-configurable Physical Coding Sublayers (PCSs as defined in IEEE 802.3-2005), one for each SHDSL line in the corresponding group (1 to 4 or 5 to 8). In IEEE 802.3-2005 terminology, each PCS is associated with a PME (Physical Medium Entity): for ASMi-54C modules, the PME is an SHDSL line (when using the M-pair mode, the PME is the SHDSL master line).
Installation and Operation Manual • Note Chapter 1 Introduction SHDSL Ethernet switch: a layer 2 switch that handles the traffic directed to SHDSL lines, through the PCS ports (the traffic handled by this switch is forwarded by the main Ethernet switch). Using a separate switch provides the flexibility needed to operate the required number of PCS ports. LRS-102 supports traffic and management flows. ASMi-54C bridge ports can also serve the management flow.
Chapter 1 Introduction Installation and Operation Manual • 10/100BASE-TX interfaces terminated in RJ-45 connectors. In addition to auto-negotiation, MDI/MDIX polarity and cross-over detection and automatic cross-over correction are also supported. Therefore, these ports can always be connected through a “straight” (point-to-point) cable to any other type of 10/100BASE-T Ethernet port (hub or station).
