4.12. LS Frontend Test

The LS Frontend Test applies to boards having a loop start front end. The LS Frontend default parameters test Dual Subscriber Line Audio-processing Circuits (DSLAC) by programming each DSLAC channel and verifying that the correct information was written. Tones are also played and verified on each DSP channel. This is a stand-alone test and does not require other network interface boards or an external loopback connector.
