Service Interface (Line) Cards 5-17
ASI-155 Line Module, LM-2OC3-SMF
ASI-155 Line Module, LM-2OC3-SMF
The LM- 2OC3 -SMF (Model SMF-2-BC) line module for the ASI-155 Front Card is a backcard
that provides a SMF intermediate range service interface. The line module connects to the ASI-155
through the StrataBus midplane. Two adjacent cards of the same type can be made redundant by
using a Y-cable at the port connectors. This is the same LM-2OC3-SMF backcard (Figure 4-8) that
is used for the BNI-155.
ASI-155 Line Module, LM-2OC3-SMFLR
The LM- 2OC3 -SMFLR (Model SMFLR-2-BC) line module for the ASI-155 Front Card is a
backcard that provides a SMF long range service interface. The line module connects to the ASI-155
through the StrataBus midplane. This is the same LM-2OC3-SMFLR backcard that is used for the
BNI-155.
ASI-155 Line Module, LM-2OC3-MMF
The LM-2OC3 -MMF (Model MMF-2-BC) line module for the ASI-155 Front Card is a backcard
that provides a MMF service interface (Figure 4-9). The line module connects to the ASI-155
through the StrataBus midplane. This is the same LM-2OC3-SMF backcard that is used for the
BNI-155.
Y-Cabling of ASI Backcard, SMF-2-BC
The LM-OC3-SMF (Model SMF-2-BC) backcards may be Y-cabled for redundancy using the
Y-Cable splitter (Model SMFY) as shown in Figure 4-10. The cards must be configured for Y-Cable
redundancy using the addyred command
BXM Cards, Access (UNI) Mode
The BXM card sets support OC-12c/STM-4 or OC-3C/STM-1 interfaces, and provide the capacity
to meet the needs of emerging bandwidth driven applications. The BXM provides high speed ATM
connectivity, flexibility, and scalability. The card sets are comprised of a front card that provides the
processing, management, and switching of ATM traffic and of a back card that provides the physical
interface for the card set.
A BXM port may be configured to operate as either a trunk or UNI port. The BXM OC-12 back cards
support either Single Mode Fiber (SMF) or Single Mode Fiber Long Reach (SMFLR). The BXM
OC-3 back cards support either Multi-Mode Fiber (MMF), Single Mode Fiber (SMF), or Single
Mode Fiber Long Reach (SMFLR).
For a further description of the BXM cards refer to, Chapter 6, BXM T3/E3, 155, and 622.
