3.4.2.1 Drop Insert Mode
The addition of one or more drop and insert multiplexers converts a simple point-to-point system into
a drop and insert system. Data, voice, program audio, and distribution (multiple drop) circuits can be
established between any two locations in a T1 drop and insert system. Drop and insert systems are
not limited to a single drop and insert multiplexer and can in fact be used to link multiple locations.
To create a drop and insert multiplexer with full module and line redundancy features, you need twp
additional CM-5RB modules and a second set of MA-235-1 and MA-235-2 module adapters. Place
these CM-5RB pairs in slots 3 and 4 in the same orientation as the first set. Then set the CM-5RB pairs
to DI-A or DI-B per the system configuration (Section 4.3 – CM-5RB Advanced Configuration Group
Menu). Figure 3-4 shows a drop and insert configuration.

Figure 3-4. Basic Drop and Insert Configuration
Drop and insert redundancy requires four common modules in a shelf, two for DI-A and two for DI-B.
It also requires special cabling between the module adapters. Table 3-1 gives MA-235-1 switch
settings. Section 2.2.4 – Drop and Insert Multiplexers and Section 2.2.5 – Drop and Insert Systems
give more information on drop and insert functionality.
3.4.2.2 Front Panel User Interface
Figure 3-5 presents the CM-5RB front panel user interface (FPUI) and switch locations. When power is
first applied to the chassis, the 4-character display on the primary and backup common module’s front
panels indicate the system multiplexing mode (Figure 3-6 and Table 3-1).
