G.5.2 ACM Operation Using the CDM-760 Front Panel
See Chapter 6. FRONT PANEL OPERATION for in-depth information about CDM-760
front panel operations.
Figure G-9 shows the CDM-760 front panel operational features:
1 LED Indicators – These eight LEDs show the summary status of key modem operations.
2 Keypad – Use the keypad to ENTER data. The keypad has six individual keys. The keys
have a positive 'click' action that gives tactile feedback.
3 Vacuum Fluorescent Display (VFD) – The VFD shows data, menus, prompts, and
messages. The VFD is an active display with adjustable brightness. It shows two lines of
40 characters each. Nested menus show options and prompts that guide you in carrying
out required actions.
G.5.2.1

Configure ACM Operation

Do these steps to configure the CDM-760 for ACM operation:
Step Task
1 Make sure the Gigabit Ethernet interface is selected and enabled. See Sect. 6.2.2.4.2 (CONFIG:
INTF) GEBIx.
Select the Tx and Rx modulation types. See Sects. 6.2.2.2.1 (CONFIG: Tx) Mod and 6.2.2.3.1
2
(CONFIG: Rx) Mod.
Program the Tx and Rx symbol rates. See Sects. 6.2.2.2.2 (CONFIG: Tx) DataTx Symbol Rate
3
and 6.2.2.3.2 (CONFIG: Rx) DataRx Symbol Rate
Enter the operating Tx Power (Sect. 6.2.2.2.4 (CONFIG: Tx) Power), Tx frequency (Sect. 6.2.2.2.3
4
(CONFIG: Tx) Freq), and Rx frequency (Sect. 6.2.2.3.3 (CONFIG: Rx) Freq).
5
Before engaging ACM, conduct a test to verify both modems are interoperable.
Figure G-9. CDM-760 Front Panel View
The GBEI1 (J5 | DATA) and GBEI2 (J6 | DATA) Gigabit Ethernet ports are functional
when the PIIC slots card is installed, or when the optional High-Speed Packet
Processor card is INSTALLED BUT DISABLED. These base unit ports are non-
functional when the optional High-Speed Packet Processor is INSTALLED AND
ENABLED. You must use the CDM-760 HTTP (Web Server) Interface to configure
Packet Processor P0 | M&C and P1 through P4 | DATA port operation (see Sect.
G.X.X).
