Physical connections to the components
Connections to the LPMs
The LPMs connect their associated LIMs to physical line facilities. In the Stinger CR
ATM DSLAM, the LPMs are connected directly to three sets of protection blocks
located to the left of the Stinger chassis in the enclosure.
The 48-port LPMs with splitters also connect to facilities providing analog voice
service (dial tone) from the central office. The integrated splitters combine analog and
DSL data service on a single copper pair for delivery to the subscriber. For specific
information connections from the LPMs, through the protection blocks, and to the
copper telecommunication facilities, see “Cabling for the 48-port LPM with splitters”
on page C-3.
Connecting the LPM
The 48-port LPM with splitters is designed to provide access to subscriber facilities for
DSL service and connection points for analog voice service. The splitters in this unit
allow both services to be combined on the same subscriber facilities. Information
about LPMs that are used with other Stinger units is provided in the Getting Started
Guide for each unit. Additional details about the connection points for the 48-port
LIM with splitters is provided in “Cabling for the 48-port LPM with splitters” on
page C-3.
Connections to the 48-port LPM with splitters are shown in Figure 3-30.
