Cables and Connectors
Line protection connections
in Stinger host units, except the OC3-ATM trunk module, use LC small form factor
connectors. Stinger OC3-ATM trunk modules use SC optical connectors. The
keyways and the transmit/receive orientation of these connectors are illustrated in
Figure B-1.

Line protection connections
All LPMs, except the 48-port LPM with splitters, have one, two, or three, RJ-21X,
50-pin telephone company connectors. The 48-port LPM with splitters has three
64-pin Tyco connectors. Both types of connectors and their pin numbering
assignments are illustrated in Figure B-2.

LPM connectors
Some LIMs include integrated line protection hardware. It is possible to connect
directly to these LIMs. Dedicated LPMs support two-wire or four-wire connections to
the end user, depending on the type of service being provided by the associated LIM.
LPMs are also available with splitters to bring DSL and analog voice service onto the
subscriber 2-wire connection. Because of these variations, details about wiring
connections for the different types of LPMs are placed in the most recent version of
the
Stinger Line Protection Module (LPM) Guide
. Details about wiring connections to
LIMs with integrated line protection are in the most recent version of the
Stinger
ADSL/ADSL2+ Annex A Line Interface Module (LIM) Guide
