Ttc t-berd 307 DS3 & DS1 communications analyzer
TTC T-BERD T1 & T3 COMMUNICATIONS ANALYZER
Includes Case, DS1 & DS3 Cables, AC Charger, & Battery
The unit is used with minor exterior scratches.
The unit runs through all menu options and appears to be in perfect working order.
The unit passes loopback tests.
* 307 DS3 Test Unit w/DS1 Option Installed
Generic Specifications for Applications:
* The T-BERD T1 Analyzer is ideal for T1 turn-up and maintenance.
* It makes it possible to Troubleshoot and isolate physical layer problems, measure VF level, frequency, and quality with the channel monitor feature.
* Network synchronization problems are also isolated easily.
* Monitor live T1 networks The instrument determines framing,coding, and pattern automatically.
* It can also detect errors for instant display on the front panel.
* Signal quality and data bits can be monitored on any DS0 channel.
* Decode the SLC data link or ESF signal and monitor signaling bits to troubleshoot problems in the field.
* Qualify T-Carrier circuits Utilize preprogrammed loop codes for intelligent repeaters to sectionalize span problems before dispatching maintenance personnel.
* Loop NIUs and CSUs from the central office with one test instrument.
* Perform automated pattern tests to test the span and identify problems rapidly.
* Isolate network synchronization problems Timing problems are identified easily.
* Compare a T1 circuit with a network reference clock to isolate timing slips.
Verify Fractional T1 Service
Use the Fractional T1 option to perform bit error rate tests on selected channels to verify transmission quality on contiguous and noncontiguous FT1 bandwidths. InsertVF tones on single DS0 channels.
Verify remote in-service circuit performance from the decoded ESF broadcast and access performance statistics by monitoring NIUswith the Enhanced ESF option.
Decode alarms and datalink messages when installing and troubleshooting SLC systems with the SLCDecode option.
The Acterna T-BERD T3 Analyzer delivers powerful features that speed testing from a versatile, lightweight battery-powered instrument that is ideal for field service technicians.
* Unmatched flexibility means tests can be carried out from a variety of access points.
* Users can verify tributaries at DS3 access points or use the instrument as a DS1 test instrument.
Timing errors are identified rapidly and the DS1 timing reference can be accessed from either DS3 or DS1 access points.
The instrument can simulate 3:1 multiplexers or cross-connects for DS3 and DS1 circuit qualification.
* Test tones, patterns, loop codes or errors on one or all DS1 channels.
* For additional testing flexibility DS1 channels can be dropped from the received DS3 signal for analysis.
Isolate network synchronization problems.
* Timing problems are identified rapidly, particularly timing impairments, a common source of errors in asynchronous and synchronous networks.
Compare a T1 circuit against a network reference clock to isolate timing slips.
Test far-end equipment with ease
Automatically loop up the far-end equipment and verify if data is being received properly on specified DS1 channels by transmitting C-bit FEAC or DS1 loop codes. Results and alarms are immediately visible on the front panel.
