If the modem is to communicate with an installed

SDCP, install the modem as described above and perform
the following steps:

1. Press the

Select

key on the SDCP. The cursor

appears in the carrier selection entry.

2. Press the F1 (

") or F2 (

) key until the carrier

number you want appears on the LCD.

The carrier number selection has a range of 1 to 8
since a single SDCP can control a configuration of
up to eight carriers. (This is only possible if the
SDU is installed.)

3. Press the

key to position the cursor on the slot

selection entry.

4. Press the F1 (

") or F2 (

) key until the slot

number (1–16) you want appears on the LCD.
Ignore the AB designator that appears on the LCD
since it is not applicable to the 3811Plus modem.

5. Press the

Select

key to place the SDCP in direct

communication with the selected modem.

The LCD displays the Top-Level menu for the
selected modem. In addition, the Front Panel LED
on the modem’s faceplate lights up.

6. Once you have determined that the modem is

installed properly and completed its power-up
self-test, rotate the circuit pack lock until it covers
the faceplate latch (

Figure 3-2

). This prevents the

modem from accidently being removed once it is
installed in a carrier.
