Chapter 2: Card Installation
T1/E1 Selection
The card includes a row of jumpers to select either T1 or E1 mode for the
spans. An example of the jumpers from the TE 405 card is shown in
Figure 6. The T1/E1 mode, in most cases, is set at the distributor before
shipment. You may want to check the setting to be certain they are set for
your specific use.

Identifying Multiple Cards
If multiple TE400 Series cards are installed in the same machine, then the
Ident
wheel can be used to control the order the cards are recognized. The
click wheel switch with the word
Ident
printed above it can be set to a
different number for each installed card. This number adjusts the order in
which the driver recognizes the card. For example: set the first card
Ident
wheel to 0, set the second card
Ident
wheel to 1, and so on. The
Ident
wheel is shown in Figure 7.
