Paradyne 3615, 3616 Power-Up Routine, Connecting to the Dial or Pstn or Switched 56 kbps Network

COMSPHERE DualFlow Data Service Units

Power-Up Routine

When power is applied, the DSU:

•Runs a Device Test on itself and the DBM.

During the tests, all indicators on the DCP light briefly and the message Power-Up Tests appears on the liquid crystal display (LCD).

•Displays the results of each test momentarily as Pass, Fail, or Abrt. (Abrt indicates that the Device Test was aborted because a network loopback was in progress during the power-up procedure.) These tests take about 20 seconds to complete.

If the DSU or DBM fails this test, follow the procedure below. Refer to Appendix A as you perform the procedures described in this guide. Refer to Chapters 4 and 5 for additional examples and procedures.

.Procedure

1.Press the key to return to the top-level menu.

2.Select Local (F1 key).

4.Press the function key directly under Confg.

5.Press the F1 key to select Opts (Configuration Options).

The Load from screen appears.

6.Press the key to bring the factory-loaded unit configurations into view, and select the appropriate configuration.

•SyBC (Synchronous Backup for a Control DSU) for a control when the router controls backup.

•SyBT (Synchronous Backup for a Tributary DSU) for a tributary when the router controls backup.

•DiDg (Dial Diagnostics) for asynchronous router-management data to be sent over the EIA-232 port via the DBM connection and user data over the V.35 port via the DDS connection.

7.Press the F1 key to SAVE the selected configuration.

The Save to screen is displayed.

8.Save the selected configuration to Activ (F1 key).

9.Press the key to return to the top-level menu, then select Local again.

10.Select the Test branch (F3). The Run Test on screen appears.

11.Select the device that Failed, the DSU or DBM.

12.Press the F2 key to run the Device Test again. The device should pass.

13.Should the device fail, contact your service representatiave. (see Chapter 1).

Connecting to the Network

Network connections are provided through the 3000 Series Carrier. Refer to Figure 3-2 as you read the following sections and set up your network connections.

Connecting to the NMS

A Model 3616 DualFlow DSU is set up for network diagnostic connection through the shared diagnostic unit (SDU), which is installed in Slot 0 of the carrier. Refer to the COMSPHERE 3000 Series Carrier, Installation Manual to set up the network diagnostic connection.

For connection of the DSU, see Appendix E of this guide. For pin assignments, see Appendix D.

Connecting to the Dial (or PSTN) or Switched 56 kbps Network

Connection to the dial network (or public switched telephone network ± PSTN) or Switched 56 kbps network for the carrier-mounted Model 3616 DSU is through a network interface module (NIM) that is installed onto the carrier's backplane (see Figure 3-2). Refer to the COMSPHERE 3000 Series Carrier, Installation Manual for additional information or to install the NIM.
