Menu Title
The third line displays the general classification of functions currently accessible
by the user (such as Alarms or Performance).
Messages
This line may display the following messages:
NMS ALARM. An error condition displayed when the unit is managed by an 8100A
that detects a duplicate address or invalid address (0 to 63 are valid). The 8100A
detects these error conditions and notifies the unit to enter into an NMS ALARM
condition. Once the error condition has cleared, (either the duplicate address is
removed or the invalid address is corrected) the 8100A notifies the unit to clear the
NMS ALARM condition, While in the NMS ALARM condition, the unit’s Status
LEDs turn from red to green and back about every half second.
NET ALARM. An error condition has exceeded the specified alarm threshold on the
network interface.
DTE ALARM. An error condition has exceeded the specified alarm threshold on the
DTE interface.
NET LOOP. A payload or line loopback is active on the network interface.
DTE LOOP. A payload or line loopback is active on the DTE interface.
TEST ACTIVE. BERT has been activated by the terminal interface, the EM8000, or
the 8100A system. While this is being displayed, alarm detection and reporting is
inhibited.
FAR END ALARM. The far end has an alarm condition (detectable only with
TxPORT-proprietary devices).
FAR END LOOP. A payload or line loopback is active at the far-end device.
FAR END TEST ACTIVE. The far-end device has a test active (this is detectable only
with TxPORT-proprietary devices).
Interface
Start Up
Once a compatible terminal is properly connected to the CSU, a terminal interface
session is started by sending a break command to the unit. If the NMS port is used,
the unit then responds with the prompt Enter Unit Address. To activate the first (or
only) unit, simply press Enter. To select a specific unit, enter the address number
of the desired unit and press Enter.
The Enter Unit Address prompt times out after 10 seconds. If this happens, send
another break command. To select another unit, exit the current terminal interface,
send a break command, and repeat the process.
If an invalid address is entered, that address is echoed to the terminal. Send a break
command to start a new session.
