Configuring the DSUs
"Procedure
To configure the Model 7511 Dual DSU:
1.Review Table 1 to determine the proper settings for your environment.
The first choice for each option (shown in boldface type) is the factory default setting. If you choose the factory default value, you do not need to change the position of the associated switch.
2.Mark any options in the table that you wish to differ from the factory default.
3.Using Figure 1 and Table 1, verify that the switch settings of each DSU on the 7511 card match your selections.
Do not modify the settings of switches not listed in the table. Any switch not designated for customer use should be in the Off position.
4.Where required, verify that the local and remote DSUs employ the same options. For example, both the local and remote DSU must use the same Line Rate and 64CC Data Scrambler settings.
