Craftek Ct100 Rs-232 Serial Interface Troubleshooting Opt. 2A The Craftek Ct100'S Rs-232 Interface (Opt. 2A) Allows The User To Connect An External Device To The Portable Test Set Over A Serial Interface. This Option Provides For Two Capabilities When In Use. The First Is Data Sourcing, Providing Enhanced Testing Of Isdn D-Channel Packet Data Capabilities. The Other Capability Is Data Logging, Allowing The User To Record Results Of Installation And Troubleshooting Tasks.

Packet Data Testing Over Rs-232 In The Data Sourcing Mode, The Rs-232 Interface Allows The User To Connect A Terminal And Initiate X.25 Packet-Switched Data Calls Over An Isdn Data Channel. This Mode Is Useful When Accessing Packet Gateways Requiring More Than A Simple Phone Number (E.G., Passwords) Or To More Fully Verify D-Channel User Applications.

The Operator Connects Their Computer'S Serial Interface To The Unit'S Auxiliary Jack (Db25-To-Rj45 Adapters Included). A Pc Communications Software Package Can Then Be Used To Send Standard Hayes-Compatible Modem Commands To Setup And Maintain A D-Channel Packet Call.

D-Channel Monitor In The Data Logging Mode, The User Can Use The Rs-232 Port To Connect A Printer Or Terminal Directly To The Unit. Details Such As Call Setup, Signaling Protocols And Measurement Results Can Be Recorded For Later Analysis. Figures 1 And 2 Provide Examples Of The Type Of Information Available When Operating In The Data Logging Mode. This Mode Of Operation Allows The User To Monitor The Events That Are Taking Place On The D Channel.

For Instance, The Craftek Ct100 Might Be Used To Monitor A Line Over An Extended Period, Recording Time-Stamped Events Such As Synchronization Loss Or Data Transmission Errors. A Problem Call Could Be Documented From Call Setup To Teardown To Trace Cpe Or Switch-Related Trouble, In The Absence Of More Complex Protocol Analyzers. Or The Technician May Simply Use The Data Logging Mode To Record Results Of The Service Verification Procedures When On-Site.
