To change a factory template using AT commands, perform the following steps. For more information on changing factory templates using AT commands, refer to Chapter 5, AT Command Set and S-Registers, in

Document No. 3910-A2-GN32.

1. Use the AT&F&W command to load the appropriate factory configuration to the appropriate storage area. Enter the following:

TYPE: AT&Fy&Wn

Where: y is one of the Factory configurations. For example:

0 for Async Dial

1 for Sync Dial

2 for Sync Leased (Answer)

3 for UNIX Dial

4 for Sync Leased (Originate)

5 for Async Leased (Answer)

6 for Async Leased (Originate)

7 for TMp (Control)

8 for TMp (Trib)

NOTE

&F0 and &F3 allow you to use AT commands after saving a factory configuration. Other selections remove AT command control. The only way to return to AT command control is through the DCP as described earlier in Using the DCP.

Where: n is one of the following storage areas:

0 for Active (Saved)

1 for Customer 1

2 for Customer 2

NOTE

These three configuration areas are nonvolatile memory locations.

Active (Saved) contains the most recently saved changes to any configuration options. In the event of power loss, the modem retrieves these configuration options. Customer 1 and Customer 2 are user-defined configuration areas.

PRESS: Return (Enter)

2. The selected factory configuration is saved.

To establish a connection with a remote modem, use the D (Dial) command. For more information on AT commands, refer to Chapter 5, AT Commands and S-Registers, in Document No. 3910-A2-GN32.

2. Disconnect the power cord from the ac power outlet, and then disconnect the dc power cable from the connector on the rear of the modem.

3. Disconnect the dial and leased-line modular cords from the modem’s rear panel.

4. Disconnect the DTE interface cable from the modem’s rear panel.

If the modem is to be removed for service, return it using the procedures described in Government

Requirements and Equipment Return.

5. Install the replacement modem as described in the Model 3910 Modem Installation section, and configure it the same way as the modem being replaced.

Model 3911 Modem Installation

CAUTION

If the Model 3911 is removed from the carrier, always use a ground strap when handling the modem. Always store the

Model 3911 in an antistatic bag when it is removed from the carrier.

The Model 3911 is designed for installation in a COMSPHERE 3000 Series Carrier which supplies both the operating power and the leased and/or dial network connections. For correct power, DTE, dial-line, leased-line, and network management cabling information, refer to the COMSPHERE 3000 Series Carrier, Installation

Manual.

The COMSPHERE 3000 Series Carrier has 17 slots which can hold up to 16 modems and one shared diagnostic unit (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 shared diagnostic control panel (SDCP). The

SDCP of the COMSPHERE 3000 Series Carrier is the user interface to the Model 3911 modem. A single SDCP can control up to eight carriers containing up to 128 compatible modems.

The installation of a Model 3911 varies slightly if an SDCP is installed on the front of the carrier. To install a

Model 3911 modem into the carrier without an SDCP, 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.

8

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 (Figure 2).

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 3911 lights. After several seconds the modem completes its power-up self-test, in which all faceplate LEDs light.

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

Figure 2. Installing a Model 3911 Modem

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 you want (1–16) appears on the LCD. Ignore the

AB designator that appears on the LCD since it is not applicable to the 391x Series modems.

9

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 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 (Figure 3) and tighten the retention screw on the circuit pack lock. This prevents the modem from accidently being removed once it is installed in a carrier.

7. Configure the modem as described in the Selecting Factory Configuration Options section.

Removing and Replacing Model 3911 Modems

CAUTION

If the Model 3911 is removed from the carrier, always use a ground strap when handling the modem. Always store the Model 3911 in an antistatic bag when it is removed from the carrier.

It is not necessary to power down the carrier to remove and replace a Model 3911 modem. Perform the following steps:

1. Rotate the circuit pack lock until the release tab is exposed.

2. Press down on the release tab and pull the modem away from the carrier’s backplane.

NOTICE TO THE USERS OF THE CANADIAN PUBLIC SWITCHED TELEPHONE NETWORK

The Canadian Department of Communications label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational and safety requirements. The

Department does not guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone line and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

CAUTION

Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

The Load Number for this equipment is listed on page A of this manual. The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device to prevent overloading. The termination on a loop may consist of any combination of devices subject only to the requirement that the total of the Load Numbers of all devices does not exceed 100.

If your equipment is in need of repair, refer to the procedures described in the Government Requirements and

Equipment Return section.
