DTC Async Card Configuration
When you press the
[Config Card]
key at the DTC Configuration screen and the card is a
direct or modem connect card, NMMGR will display the screen appropriate for the DTC.
The screen for a DTC 72MX Asynchronous card is shown in Figure 3-9.

1. Verify that the DTC name and card number displayed are correct.
2. (Optional) Enter the port group type. The valid types are D for direct connect and M
for modem connect. The default is D.
3. Press the
[Tab]
key to move the cursor to the first port on the card. Enter an ldev
number for this port in the “Ldev” field.
Ldev numbers used for each port on the DTC must be unique.
For example, you can use ldev number 100 for port 0 of the first card, and increment
the ldev number by 1 for each consecutive port.
So a DTC 72MX with 3 asynchronous cards (a total of 72 ports) would be assigned
ldev numbers 100 through 123 for the 24 ports on the first card, 124 through 147 for
the ports on the second card and 148 through 171 for the ports on the third card.
For the second DTC, you would start with an ldev number greater than 171.
NOTE Pressing the
[Show Ldevs]
key will display a list of all the ldev numbers configured in
NMMGR in addition to the DTC name, card type, and profile name.
