990-GM/2
ADSLx Golden Modem
Quick Reference Guide
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
carried in the front pouch of the 990 softcase. The pouch flap can be opened for
connecting the Ethernet cable or for viewing the GM/2 Status indicators.
GM/2 Status Indicators
•POWER: green LED that is located in the upper right corner of the ENET jack.
Indicates that the 990 has applied power to the GM/2 during operation of the
DSL Modem Test.
•SYNC: green LED that is located in the upper left corner of the ENET jack.
Indicates the following:
•Flashing (slow or fast): the GM/2 is in the process of training with a far-end
ADSLx DSLAM modem via the DSL Test Cord.
•Steady: the GM/2 has trained with a DSLAM modem, and link statistics are
available.
GM/2 Connectors
990: RS232 control / power jack that is connected with a flat cable to the 990.
The cable is secured to the GM/2 990 jack and removable at the 990 serial port.
This allows you to plug a standard serial cable into the 990 for downloading
new program versions or uploading stored data files to a PC.
DSL: RJ11 jack that is connected with the attached DSL Test Cord to the line
under test. The DSL Test Cord (RJ11-to-RJ11/Test Clip cable) is coiled inside the
Test Lead pouch. It is connected to the line under test either by attaching the Tip
and Ring clips to a wiring terminal or by inserting the RJ11 plug into the NID
connector or house wiring RJ11 jack.
ENET: RJ45 jack that is used to connect the supplied Ethernet cable to a PC.

Running a DSL Modem Test
To run a DSL Modem Test:
1. Disconnect the subscriber’s ADSLx modem from the line under test.
2. Connect the GM/2 DSL Test Cord (coiled inside the 990’s Test Lead pouch) to
the subscriber’s line, using either the cable’s RJ11 plug or the Red & Black
(Ring & Tip) test clips.
3. Turn on the 990.
4. Select DSL Modem Test from the CopperPro 990 Main menu. Press
Setups and enable the desired emulation modes.
Note
The default enables all modes.
5. Press TEST.
The primary Modem Results screen is displayed. Results fields are blank.
An hourglass (in the lower left corner) indicates that the test is in progress.
The Modem Status line in the upper right corner displays the real-time
status of the process:
a. Power Up: the 990 is applying power to the GM/2 (POWER LED is
on).
b. Booting: the GM/2 is booting its operating system.
c. Connecting: the GM/2 is training with the far end DSLAM (SYNC
LED flashes slow, then fast).
d. Showtime: the GM/2-DSLAM link is up and statistics are available
for retrieval (SYNC LED is on steady).
e. Test Completed: link statistics are displayed (SYNC LED is on
steady).
Primary link statistics are available on Page 1 of the Modem Results screen
and secondary statistics are listed on Page 2 (to display, use the More
softkey).
6. To refresh the Modem Test results screen, press TEST again.
7. To change the modem emulation mode(s), press Setups. Then, press TEST.
The GM/2 will reconnect with the DSLAM in the new mode.
8. To save both pages of results, press the Save Results softkey. Enter the
Cable, Pair, and Telephone Number in the appropriate fields.

9. Press the Bits / Bin softkey on the primary Modem Results screen to
retrieve encoding data from the GM/2 and to display the associated graph.
This graph shows the number of bits encoded at each DMT bin. It is viewed
and operated in the same manner as the 990 ADSL Auto-Test Bits / Bin
graph. Refer to the 990 Users Guide for details.
If the GM/2 fails to establish a link with the DSLAM, a communications error
message is displayed, and the speaker chirps to signal a failure.
10. To initiate another connection attempt, press TEST again.
11. To remove GM/2 power or to reset and re-initialize the modem, press BACK
from the primary Modem Results screen.
This returns you to the Main menu.
The GM/2 is powered until the DSL Modem Test program is exited, allowing
you to conduct subsequent tests without the initial “booting” delay.
Note
To conserve 990 battery power, limit the time spent in active mode or
connect to the external charger while testing.
12. To ping the network, press the Ping softkey on the secondary Modem
Results screen. Then, do the following:
a. Press the Setups softkey.
b. Enter Ping Setups information (see 990DSL Series II Users Guide
for Ping setup details).
c. Press TEST.
Network ping test results are displayed.
13. After a successful connection, the GM/2 can be used to access the Internet
over the subscriber’s ADSLx line:
a. Connect the supplied Ethernet cable between the GM/2 ENET jack
and the Ethernet port of a PC.
b. Access the web via a standard browser program.
