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.
