ADTRAN DSU IQ Remote Configuration Capability
Introduction
IntroductionIntroduction
Introduction
Remote configuration is a very useful feature of the ADTRAN DSU IQ. Using a VT 100
terminal session and local unit, a user may configure the units at remote sites. This
process is non-disruptive to customer data. For example, in Figure 1 the user could
remotely configure the DSU IQ at remote site #1 or remote site #2 from the host DSU IQ.
In addition, either remote DSU IQ could remotely configure the host DSU IQ. It should
be noted that due to the fact that there is not a virtual circuit connecting the two remote
sites, neither remote site DSU IQ could remotely configure the other remote site DSU IQ.
The host site communicates with remote site #1 via DLCI 16 and remote site #2 via
DLCI 17. Remote site #1 sends data to the host site via DLCI 18 and remote site #2 sends
data to the host site via DLCI 19.

Directions for the Remote Configuration Process
1. Connect the straight-through RJ45 silver satin cable provided by ADTRAN to the
control port of the unit. Connect the other end of the cable to the RJ45 to DB25
adapter provided. Only use the ADTRAN adapter part number 3196.ADPT005.
Other vendor adapters will not work. Connect the DB25 end of the adapter to the
COM port of your computer. If your computer COM port is a DB9, a DB9 to
DB25 adapter will be necessary.

2. Open a terminal emulation program using the parameters 9600 bps, 8 data bits, 1
stop bit, and no parity. At this point, you should see a blank screen. Press return
several times and the login screen shown in Figure 2 will appear.

4. Choose 1 for remote DLCI and enter the remote DLCI. The remote DLCI is the
DLCI on which the data is sent to the remote site, not the DLCI of the remote site.
Using Figure 1, when the user at the host site is remotely configuring the DSU IQ
at remote site 1, the remote DLCI would be 16. When the user at remote site #1 is
remotely configuring the host DSU IQ, the remote DLCI would be 18. Enter the
remote DLCI, select 2 for begin remote session and press ENTER. The screen in
Figure 4 will appear.

Troubleshooting the Remote Configuration Process
1. If you are unable to see the initial login screen, there may be a physical
connection problem.
o Verify that the correct computer COM port is being used. This may be
accomplished by connecting to another device, such as a modem.
o Verify the proper ADTRAN RJ45-DB25 adapter is connected. The
adapter is labeled with ADTRAN part number 3196.ADPT005.
o Verify that the RJ-45 silver satin cable is pinned out with all eight pins
straight through the cable. Orient the two RJ-45 connectors with the tab
down and the gold pins pointing away from the user. The same color wire
should be present in each position, left-to-right, on both RJ-45 connectors
as shown in Figure 7.

Verify that the RJ-45 silver satin cable is plugged into the control port on
the back of the ADTRAN DSU IQ.
2. If you are able to see the initial login screen but the remote configuration session
fails, the screen shown in Figure 8 will continue to be displayed after pressing a
key on the computer.

To return to the Login screen, press Ctrl L twice. This should disconnect the
remote login session and bring up the initial screen of the local unit as shown in
Figure 9.

There are four possible reasons that could cause a remote configuration session to
fail:
• The remote DSU IQ is not powered on or not connected to the frame relay
circuit.
• There is a problem with the frame relay circuit.
• The local or remote DSU IQ is in alarm.
• An incorrect remote DLCI was used. To verify that the correct DLCI was
chosen, from the VT 100 terminal session, select Local Login to connect
to the local unit. From the main menu, select View Statistics, DLCI List,
and the screen shown in Figure 10 will appear.

This screen shows DLCI 18 is active (A). This tells the user that DLCI 18 is being
advertised by the frame relay switch as valid for this site. If the user entered any number
other than 18, that DLCI was incorrect and therefore caused the remote configuration
failure. The DLCI must be active in order for the remote configuration to work. If the
status is I for inactive, the customer should contact the telephone company and report that
their DLCI is inactive.
