This is a suggested sequence for testing the
Multiserver 500.
1. Perform the EEPROM test. If it passes, it verifies
that the Multiserver 500 can store and retrieve
data from the EEPROM.
2. Perform the Self-Test. If this test passes, the
internal circuits of the local Multiserver 500 are
operating properly.
3. Perform the Local Data Loopback Test. If this
test passes, the data portion of the local serial
interface module is operating properly.
4. Perform the Local Composite Loopback Test.
This test verifies that the Multiserver 500 can
digitize voice as well as multiplex data and voice.
5. Perform the Remote Composite Loopback Test.
If this test passes, it
verifies that the link is
operational, that the local and remote
Multiserver 500s can sync up, and that the
remote Multiserver 500 responds to commands
issued by the local Multiserver 500.
6. Perform the Remote Data Loopback Test. With
the link up and running, this test can be used
any time if a problem is encountered along the
data channel. Since this test does not interfere
with normal voice traffic, the voice/fax channel
may be used by the operators at each end to
compare test results.

To perform the EEPROM test from the
asynchronous terminal connected to the Command
Port connector, enter:
>DI EE <cr>.

NOTE: Do not invoke any commands until the
EEPROM test is completed.
The test will last approximately 5 seconds, and the
TM LED will be on for the duration of the test.

You can initiate the self-test from the Command
Port menu. Its structure is similar to the automatic
self-test, except that it runs in the background.
To perform the self-test from the asynchronous
terminal connected to the Command Port, enter:
>DI SELftest <cr>.
To perform the self-test from the LCD/keypad,
follow this path.

Test results are evaluated as follows:
If the DSP test fails, the TM LED will flash. For
other test results, access the self-test portion of the
STATUS menu from the LCD/keypad, or enter the
command
SH S
from the Command Port
terminal.

The local data loopback verifies that the serial
interface module circuits are capable of
bidirectionally processing user data. There is no
internal data source included and the remote data
channel is not operational during this test.
To run the test, see Figure 7-3 and proceed as
follows:
1. Connect an asynchronous terminal to the DATA
CHANNEL connector of the Multiserver 500.
