Older Version(s):
The E911 CAMA Trunk Direct Interface card (RMCU) enables cost-effective connection to the
Enhanced 911 locator services without third-party equipment.
RMCU supports two subassemblies (RCMS) that provide a total of up to four ports as shown in
Figure 4-24. Only one RMCU PCB can be installed in a Strata CTX670 system.
The RMCU has no CAMA circuits. It requires one RCMS subassembly to provide one or two
CAMA trunks and two RCMS PCBs to provide up to four CAMA trunks.
Location of the RCMS LEDs are shown in
given in Table 4-15.

RCMS Subassemblies Installation

1. Attach one or two subassemblies (RCMS) to the connectors on the RMCU as shown in
4-24. If only one RCMS is to be installed, install it in the bottom position.
2. Apply firm even pressure to ensure that the connectors are properly seated in the RMCU
connector blocks. If they are seated properly, a light resistance is felt when you pull the units
away from the RMCU.
