The T1-IMA LIM
Two T1-IMA LIMs are available. One module supports up to 8 T1 connections
(STGRRT-LIM-T1-8), the other module supports up to 24 T1 connections
(STGRRT-LIM-T1-24). Both modules support UNI and PNNI ATM connections.
Under a special software license from Lucent Technologies, these modules also
support inverse multiplexing for ATM (IMA). For complete hardware specifications
and information about configuring the T1 module, see the
Stinger T1 and E1 Modules
Guide
.
The T1 module is shown in Figure 2-9.

Checking the LPMs
Each LIM installed in the unit must have a corresponding LPM in the adjacent slot to
the left of the LIM. Slots that are not occupied by modules must be masked with
blank covers to ensure proper air flow through the unit. The LPMs provide the actual
connection points to the physical line facilities.
