Chapter 1 Introduction Installation and Operation Manual
1-12 Functional Description ASMi-54C LRS-102 Ver. 2.0
• 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).
Timing Subsystem
The timing subsystem generates the clock and timing signals required by the
transmit paths of the module.
Local Management Subsystem
The local management subsystem performs three main functions:
• Controls the operation of the various circuits located on the ASMi-54C module
in accordance with the commands received from the CL module through the
LRS-102 management channel.
The management subsystem in an ASMi-54C module cannot manage remote
units connected to SHDSL ports through the
eoc .
• Stores the application software of the ASMi-54C module. The software can be
updated through the CL module.
• Controls the routing of management traffic through the desired link
interfaces, in accordance with the management mode selected by the user for
each link interface.
ASMi-54C Ethernet ports and bundles can also support inband management,
when attached to the LRS-102 management flow.
Diagnostics
Performance statistics for the SHDSL and Ethernet ports may be obtained and
analyzed via the LRS-102 management system.
The ASMi-54C ports support the collection of performance diagnostics in
accordance with the requirements of ITU-T Rec. G.991.2.
