User Interface Configuration Options

MasterCom:Disab

Next Enab Disab Prev

Master Communication Unit. Specifies which circuit card in the 3000 Series Carrier is configured as the Master Communication Unit. This is the circuit card that provides the shared communication (COM) port connection for the rest of the carrier. The circuit card that is configured as the Master Communication Unit can have an external PC (supporting Front Panel Emulation) connected to Port 2 on the Auxiliary Backplane to provide access for all Models 3151 and 3161 circuit cards in the carrier. The Master Communication Unit usually resides in Slot 1 of the carrier, but this is not mandatory. Only one card per carrier can be configured as the Master Communication Unit.

Enab ± This is the Master Communication Unit for the carrier.

Disab ± This is not the Master Communication Unit for the carrier.

NOTE: This configuration option is only displayed for Model 3161 DSU/CSUs.

Com Use: ASCII

Next SNMP ASCII Term Prev

Communication Port Use. Specifies how the communication port is used.

SNMP ± Specifies that the communication port is to be used as the management link to an external SNMP manager.

ASCII ± Specifies that the communication port will be used as a proprietary ASCII port. This configuration option supports Front Panel Emulation software and ASCII alarm messages.

Term ± Specifies that the communication port is to be used as an async terminal interface. This configuration option supports configuration and device management from a terminal.

NOTE: Only one port (communication or modem) can be configured as the SNMP management link at a time. If the Modem Use configuration option is set to SNMP, only the ASCII or Term selections are available for this configuration option.

Com Type: Async

Next Async Sync Prev

Communication Port Type. Specifies whether the port uses synchronous or asynchronous communication when the port is configured as the SNMP management link.

NOTE: This configuration option is not available and is not displayed if the Com Use configuration option is set to ASCII. In this case, the communication port is always asynchronous.

Com Clk: Int

Next Int Ext Prev

Communication Port Synchronous Clock. Specifies whether the port uses internal (Int) or external (Ext) clocking when the communication port is configured for synchronous operation. This configuration option reverses the direction of the clock (TXD, RXD) interchange circuits and allows the port to accept clocking from an external device. Connection to another DCE requires the use of a crossover cable.

NOTE: This configuration option is not available and not displayed if the Com Type configuration option is set for asynchronous operation.
