DTE Connection  
Use the following procedures to connect the EIA-232-D cable and ferrite choke from  
the modem to the DTE:  
1. Make sure the modem’s rear panel power switch is Off.  
2. Connect the DB-25 plug on the cable to the DB-25 socket labeled DTE on the  
modem’s rear panel. Use a small screwdriver to fasten the cable to the modem.  
3. Connect the other end of the cable to the DTE. Use a small screwdriver to fasten  
the cable to the DTE.  
To ensure compliance with FCC Part 15 Regulations, a ferrite choke must be installed  
on the EIA-232-D interface cable.  
1. Open the ferrite choke and place it around the DTE cable as close as possible to  
the connector attached to the modem.  
2. Close the two halves around the cable and snap the ferrite choke shut, pressing  
down on the plastic latch to secure it.  
3. Install a cable tie behind the ferrite choke to prevent it from sliding along the cable.

Customer-Supplied Equipment for Model 3811  
The following customer-supplied equipment is required for the installation of a  
Model 3811 modem:  
H
H
A COMSPHERE 3000 Series Carrier.  
A male-to-female 50-pin mass termination cable. One Network Interface Module  
(NIM) for modems installed in Slots 1–8 and one NIM for modems installed in Slots  
9–16 (required for dial-line applications).  
H
One of the following modular or 50-pin dial or leased network interfaces:  
— RJ11C for single line dial permissive applications  
— RJ21X for multiple line dial permissive applications  
— 66 punchdown block or other demarcation device  
H
H
One 6-position to 6-position modular cord (required for network management  
applications).  
A Shared Diagnostic Unit (SDU) (required for network management applications).  
Model 3811 Installation  
The Model 3811 is designed for installation in a COMSPHERE 3000 Series Carrier  
which supplies operating power and the dial and/or leased-line network connections.  
For correct power, DTE, dial-line, leased-line, NIM, and network management cabling  
information, refer to the COMSPHERE 3000 Series Carrier, Installation Manual,  
Document No. 3000-A2-GA31.  
The installation of a Model 3811 varies slightly if an SDCP is installed on the front of the  
carrier. To install a Model 3811 modem into the carrier without an SDCP, perform the  
following steps:  
CAUTION  
If the Model 3811 is removed from the carrier, always use a ground  
strap when handling the modem. Always store the Model 3811 in an  
antistatic bag when it is removed from the carrier.  
8
 
1. At the rear of the carrier, install the rear connector plate. Make sure the plate uses  
the same slot position as that intended for the modem.  
— Loosely fasten the plate. This allows for slight adjustments later when  
installing the modem.  
2. At the front of the carrier, hold the modem vertically, with the latch on its faceplate  
in the open position, and insert it into the top and bottom card guides of one of the  
slots numbered 1–16.  
— Slide the modem into the slot, aligning the modem with the rear connector  
plate, until the backplane connector and DTE connector seat firmly into the  
back of the carrier. The faceplate latch automatically closes as you push the  
modem into the carrier. To lock the modem into the carrier, press the faceplate  
latch until a click is heard.  
3. If the carrier is ON, the Power LED on the faceplate of the 3811 lights. After  
several seconds the modem completes its power-up self-test in which all faceplate  
LEDs light. If the modem fails, the Alrm LED on the faceplate flashes.  
— Return to the rear of the carrier and tighten the rear connector plate.  
9
 
If the modem is to communicate with an installed SDCP, install the modem as  
described above and perform the following steps:  
1. Press the  
key on the SDCP. The cursor appears in the carrier selection  
Select  
entry.  
2. Press the F1 (") or F2 () key until the carrier number you want appears on the  
LCD.  
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.  
5. Press the  
key to place the SDCP in direct communication with the  
Select  
selected modem.  
— The LCD displays the Top-Level menu for the selected modem. In addition,  
the Front Panel LED on the modem’s faceplate and the OK LED on the SDCP  
light.  
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.  
This prevents the modem from accidently being removed once it is installed in a  
carrier.
