Drop and Insert Application MX410/MX412 System Manual
3-8 PRELIMINARY 61189500L1-1B
Setup
Connect the DS1 from which the DS0s will be dropped to the DS1 1 RJ. Connect the other
DS1 to which the DS0s will be inserted to the DS1 2 RJ. Connect the other DS1s using the
other RJ connectors on the front panel. For more information, refer to “DS1 Ports” on page 4-6
Starting from the default mapping the DS0s can be dropped and inserted using the Quick
Setup menu (see Figure 5-24 on page 5-38). Select each port (1-5) to which a DS0 needs to be
dropped from the incoming DS1. For each port select the DS0(s) in DS1 1 to be dropped to
that port. Then, select each port and DS0 that needs to be inserted into the other DS1. For
each DS0 to be inserted select the DS0 in DS1 2 to insert that DS0. Using the Cross-Connect
Mapping menu, select each DS0 that is to be dropped to other DS1 ports as well. Select the
Map Multiple DS0’s option and then select the range of DS0 and DS1 1 to be dropped to DS1
2 and enable Robbed Bit Signaling if applicable.
For each DS0 dropped out of the incoming DS1 (DS1 1 in this example), that does not have a
DS0 dropped or inserted into the corresponding DS0 in the other DS1 (DS1 2 in this example),
map the remaining DS0s to continue the data downstream. Any unmapped DS0 will transmit
all ones.
The following six figures show an example of setting up a drop and insert application. Figure
3-8 shows the Quick Setup menu before any DS0s have been dropped.
