Compatible Systems 5.4 manual System Configuration Dialog Box, Bandwidth Allocation

226 Chapter 14 - General

Invert Data

This checkbox determines whether data will be inverted. Data inversion can be used to meet pulse density requirements. Always leave this unchecked unless otherwise instructed by your ISP.

•If checked, data will be inverted. If a DSU at one end of a DS3 line inverts its data, then the DSU at the other end must do the same.

•If unchecked, data will not be inverted. This is the default setting.

Bandwidth Allocation

This pull-down menu allows you to select the data rate for the CSU/DSU. This can be used to set the throughput to match the bandwidth provided by your NSP (Network Service Provider). The values are specified in megabits per second, using an underscore ( _ ) as the decimal point (e.g., 3_158 is 3.158 Mbps). Both ends of the DS3 connection must have the same rate specified. Unless the remote end is a Larscom CSU/DSU (or equivalent) or another Compatible Systems DS3 interface, the default setting of 44_210 must be used.
