Operating the DSU

Expanded Health and Status

Expanded Health and Status (Expan) only appears during automatic dialing. It retrieves Health and Status information for the local DSU after an automatic backup attempt has failed, or when there is a disconnect after a successful connection.

If the right arrow (→ ) appears to the right of Expanded

H/S, there is more than one message. Press the key to see the next message.

Subnetwork Health and Status

Subnetwork Health and Status (Subn) displays status information from a DSU's subnetwork (all DSUs and DBMs assigned to that DSU's active poll list). The downstream network addresses and current statuses are listed. To page through tributary addresses:

•Press the F1 key ( ↑ ) for the next highest network address.

•Press the F2 key ( ↓) for the next lowest network address.

DTE Status

The DTE status subbranch provides a snapshot status of the local or remote unit's external DTE interface.

•For the local DSU status, the display is sampled and updated every 2 seconds.

•For the remote DSU status, only one set of states is returned based upon a monitoring period of approximately 3 seconds.

The DTE interface statuses are displayed in sets. Use

the or key to scroll each set of lead statuses into view.

Circuit Quality

Circuit Quality (CircQ) shows the level and quality of the signal being received from the network by the DBM. This subbranch is only available for a V.32 DBM.

Identity

Identity (ID) displays a listing of the DSU's model and serial numbers, the equipment installed (DBM or TDM/Flex), software/firmware versions, the network address, the DDS or DSU's rate, the DBM's rate, and whether the TDM/Flex is currently activated.

.Procedure

1.Press the key to scroll ID into view.

2.Press the function key (F1, F2, or F3) directly below the selection. One field at a time is displayed.

3.Press the key to display the information, one display (screen) at a time.

Table 4-1 lists the Identity information provided about the DSU and its equipment.

Terminal Power

Terminal Power (TPwr) displays the status of the connected DTE's EIA-232 and V.35 interface (connector). The DSU checks the state of the RTS lead to determine when the DTE is ON.

•When the voltage is less than ±3V or greater than +3V for both the EIA-232 and V.35 interfaces,

ÐThe second line displays On if power is detected.

ÐThe second line displays Off if no power is detected.
