Supply Of V21/V 23 E1 Convertor Modemv21/V 23 E1 Convertor Modem,V21/V 23 E1 Convertor Modem Equivalent To Cygnus 835 For Automatic Changeover Between E1And Quad Copper Cable Of Bpac Circuits At Stations, Should Convert Itu-T V.21/V.23 Signals To E1 Format,ForOnward Transport On A 2.048 Mbps E1 Stream Via A G.703Interface. The Analog Interface Provided On The Unit IsCompatible With Itu-T V.21/V.23 And Allows Transport Of Full-Duplex Voice Band Analog Modem Signals. AutomaticChangeover To Bypass Copper Circuit: This Automatically Switches Data Traffic Between The Axle Counters To ABypass Copper Circuit If (A) The E1 Link Fails, Or (B) If The Convertor Is Powered Off For Some Reason. Bypass LinkChecking: The Bypass Copper Circuit Is Constantly Checked For Availability As Long As The E1 Link Is Up. V.21Signal Monitoring: Status Of The V.21 Signal Between The Unit And The Connected Axle Counter Should Be CheckedContinuously. Potential Free Alarm Relay Contacts: Indications And Alarms For Bypass Link Down, And Loss OfV.21 Signal. Sufficient Relay Contacts To Be Provided For Extending To Datalogger Or For Raising An Alarm Circuit.Event Logging Facility Sms Alert: Manufactured Using Industrial Temperature Grade Components.
