Configuration Options
Self-Test: Enab
Next Enab Disab Prev
Initial Self-Test. Specifies whether the E1 NTU performs a device self-test at power-up and after a device reset.
Enab – Enables a self-test.
Disab – Disables the self-test.
Com Use: ASCII
Next SNMP ASCII Daisy
Communication Port Use. Specifies how the communication port is used. The communication port can be configured for
only one use (each use is mutually exclusive): it can be configured as the management link to an external SNMP
manager, it can be configured as a proprietary ASCII port, or it can be configured as an SNMP management link daisy
chained to another 33xx Series device.
SNMP – Specifies that the communication port is used as the management link to an external SNMP manager.
ASCII – Specifies that the communication port is used as a proprietary ASCII port supporting Front Panel Emulation
software and ASCII alarm messages.
Daisy – Specifies that the communication port is used as an SNMP management port that is daisy chained to the
auxiliary port of an another 33xx Series device.
NOTE: SNMP and ASCII selections can be made using the ifAdminStatus MIB object (up = SNMP, testing = ASCII).
NOTE: The Daisy selection requires the use of a customer-supplied, 8-pin-to-8-pin, straight-through cable. Whenever
the cable is connected or disconnected, change the Daisy selection to another selection, and then back to Daisy,
to ensure that the correct parameters have been negotiated for the link layer.
Com Type: Async
Next Async Sync Prev
Communication Port Type. Specifies whether the communication port uses synchronous or asynchronous operation when
it is configured as the SNMP management link.
Async – Configures the communication port for asynchronous operation.
Sync – Configures the communication port for synchronous operation.
NOTE: This configuration option is not available if the Com Use configuration option is set to ASCII or Daisy. In these
cases, the communication port is always asynchronous.
Com Clk: Int
Next Int Ext Prev
Communication Port Synchronous Clock. Specifies whether the communication port uses internal or external clocking
when it is configured for synchronous operation.
Int – Configures the communication port for internal clocking.
Ext – Configures the communication port for external clocking.
NOTE: This configuration option is not available if the Com Type configuration option is set to Async.
