General Description
The 990-GM/2 (Golden Modem) appliqué is used with the CopperPro 990 DSL
Modem Test for testing ADSL, ADSL2, and ADSL2+ services. It contains an industry-
standard ADSL/2/2+ modem (ATU-R) that is housed in a compact metal case and

and Ring clips to a wiring terminal or by inserting the RJ11 plug into the NID
connector or house wiring RJ11 jack.
