The NSA 400 simulates a variety of impairments which can be used to test according to the following National and International standards:
• ANSI T1.601 ISDN Basic Access Interface
• ANSI Technical Report on HDSL
• ANSI T1.413, Issue I
• ANSI T1.413, Issue II
• ANSI Proposed Working Draft for HDSL2
• ITU Standard for G.lite
• ETSI TS 102 080 ISDN Standard
• ETSI ETR 152 HDSL Standard
• ETSI ETR 328 ADSL Standard
The user can set the impairments using the IEEE or the RS-232 interface. The command language in both cases is based on the Standard Commands for Programmable Interfaces (SCPI) standard
