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.
4. Enter the profile name for each port in the “Profile Name” field.
A profile for the port defines the characteristics of the device to be
connected to that port.
