assignments to MLT and other test equipment
(PLN-8991-103, Vol 1, Engineering Manual (No longer provided))
Note: The following is for assignments on the ISM shelf located at posi-
tion 53 on the frame. The ISM shelf located at position 39 will not
have NTFX44 and NT2X90 assignments in shelf slots 6 through

Note: Each RIM module is paired with a digital line module (DLM)
and serves as an interface between the DLM at a remote site and
the DS1 links to a line group controller or line trunk controller at
the host. The RIM module may be as far as 241 Km (150 miles)
from the DMS network.
Note: For further description of the following RIM shelf packs, see the
“Circuit Pack Description” within this QRG or see NTP
