Operation DMD2401/DMD2401L/DMD2401 IBS/IDR Satellite Modem
3-12 TM065 – Rev. 3.3
3.11 Drop and Insert Mapping
The following displays under Interface D&I Setup ( both Tx and Rx ), are editing displays only:
SATCh TS
Enter to Edit
Any changes made in these displays are made on the screen, but are not entered into the
modem. Once these menus are configured, the Mapping Menu must be used to actually enter
the settings into the modem.
Example :
For a modem w/ Drop & Insert enabled at a data rate of 256 (with timeslots assigned 1-1, 2-2,
etc.). At a data rate of 256, the modem will allow 4 channels to assign timeslots to. Under the Tx
Menu, assign the timeslots that are to be used to the 4 channels. CH1 is assigned to TS1
(Timeslot #1), CH2 to TS 2, CH3 to TS3 and CH4 to TS4, must be depressed after
assigning each individual TS. Once the timeslots are assigned to the channels, use the Left or
Right Arrow Key to scroll to the Mapping Menu. This menu will appear in the following way:
Map Copy
******* *******
Note: The ******* will be one of several words, just look for the “Map Copy” display).
This is the menu where the channel assignments are actually entered into the modem. To do
this, perform the following steps:
For the Transmit Side:
1.
Push to get the flashing cursor.
2.
Use the Up Arrow Key to make the left portion of the display read “TX EDIT”.
3.
Use the Right or Left Arrow Keys to switch the flashing cursor to the right portion of the
display.
4.
Use the Up or Down Arrow Key to make the right hand portion read “TX ACTIVE”.
5.
The mapping display should now look like this:
Map Copy
TX EDIT > TX ACTIVE
6.
Push to enter this command. This tells the modem to configure to the settings
that were assigned in the Channel/Timeslot display.
