Protector orientation details
The cables from the LPMs connect to the protected (inside) side of the protection
blocks. Another group of cables connect the unprotected (outside) side of the
protection blocks to the copper facilities. The tips and rings of the outside plant cables
and the LPM cables terminate on the protection plugs of the protection blocks as
shown in Figure C-6.

For information about the type of protection elements that should be installed, see
“Protection block elements” on page D-5.
Connection block LPM cable associations
Each pair of protection blocks have similar cable connections to an LPM in the
Stinger unit. The connection of the LPM connectors P2801, P2802, and P2803 to the
protection blocks is described in Table C-3 and Table C-4.
LPM connections for the top protection block (blocks 1, 3, and 5) are detailed in
Table C-3. When a T1/IMA LIM is installed in one of the LIM slots, up to 24 4-wire
ports are supported and mapped as shown. The numbering for protectors on P1, P3,
and P5 corresponds to the protector numbering in Figure C-5 on page C-6.
