Model 3811Plus Installation

The COMSPHERE 3000 Series Carrier has 17 slots which can hold up to 16 modems and one SDU. The SDU is required when the modems in the carrier are controlled by an NMS, or when multiple carriers in a cabinet configuration are to be controlled by a single SDCP. The SDCP of the COMSPHERE 3000 Series Carrier is the user interface to the 3811Plus modem. A single SDCP can control modems in up to eight carriers.

To install a 381 1 Plus modem into the carrier, perform the following steps.

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.

CAUTION:

Always use a ground strap when handling a modem. Always store a 3811Plus modem in an antistatic bag when it is removed from the carrier.

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. To lock the modem into the carrier, press the faceplate latch until a click is heard.

3. Rotate the circuit pack lock(s) into the closed position, and tighten the screw.

4. If the carrier is connected to power, the Power LED on the faceplate of the 3811Plus lights up. After several seconds the modem completes its power-up self-test in which all faceplate LEDs light up.

If the modem fails, or an alarm condition exists, the Alrm LED on the faceplate lights up or flashes. It may be possible to run a diagnostic self-test from the SDCP. See Test Branch in the COMSPHERE 3800Plus Modems User’s Guide.

Return to the rear of the carrier and tighten the rear connector plate.

5. Connect an RS-232D DTE cable to the top connector of the rear connector plate. (The bottom connector is unused.)

6. Connect the other end of the cable to your DTE.

Diagnostic Control Panel

The Diagnostic Control Panel (DCP) is the user interface to the modem. It provides a 2-line, 32-character liquid crystal display (LCD), a keypad, speaker grill, and status indicators.

A Shared DCP (SDCP) is used to manage carrier-mounted 3811Plus modems. The Select key is used to connect the SDCP to a modem or other device in a specific carrier and slot location. Press the Select key, then enter the modem carrier (1–8) and slot (1–16) numbers. Once the modem is selected, operation of the SDCP is the same as for the standalone DCP.

Note that 3810Plus and 3811Plus are the model names for the model numbers 3980 and 3981, respectively. The modems collectively are called 3800Plus modems.

United States – Notice to Users of the Telephone Network

1. This equipment complies with Part 68 of the FCC rules. On the equipment is a label

that contains, among other information, the FCC registration number and ringer equivalence number (REN) for this equipment. The label is located on the bottom of the Model 3810Plus modem and on the circuit card assembly of the Model 3811Plus. If requested, this information must be provided to the telephone company.

2. For the standalone modems, the Universal Service Order Code (USOC) for

Permissive mode is RJ1 1C; the Canadian equivalent is CA11. For the carrier-mounted modem, the USOC for Permissive mode is RJ21X (Canadian CA21A).

Page 27

3. The Ringer Equivalence (REN) is used to determine the quantity of devices which

may be connected to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to the line, as determined by the total RENs, contact the telephone company to determine the maximum RENs for the calling area.

4. If the 3800Plus modem causes harm to the telephone network, the telephone

company will notify you in advance that temporary discontinuance of service may be required. But if advance notice is not practical, the telephone company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is necessary.

5. The telephone company may make changes in its facilities, equipment, operations,

or procedures that could affect the operation of the equipment. If this happens, the telephone company will provide advance notice in order for you to make the necessary modifications in order to maintain uninterrupted service.
