Telecommunications Techniques Corporation T-BERD 224 Analyzer
Telecommunications Techniques Corporation
Modelo: T-BERD 224
Data: 1991
Categoria: Instrumentos de medição
Grupo: Analyzer
Descrição: PCM Analyzer

The T-BERD 224 PCM Analyzer is a comprehensive, full-duplex, T1 channel access Test Set. It provides test and monitor access to VF, DSO, fractional T1 (FT1), DSOA, DSOB, and datalink channels from virtually any T1 access point. Single and dual drop capabilities allow users to hear or observe live voice and data traffic. Bi-directional drop and insert capabilities allow users to insert test tones or data into a channel(s) in either T1 transmission direction to perform out-of-service tests. The T-BERD 224 has two T1 receivers and two T1 transmitters, it may be placed in-line, at which point it provides “hitless” drop and insert in either direction. Typically used in central offices and at the customer premises, the T-BERD 224 provides circuit installation and fault isolation testing capabilities. It allows users to easily troubleshoot problems with voice and data circuits that are transmitted within T1 interoffice trunks, digital loop carrier systems, and dedicated leased circuits. Remote control capabilities allow the T-BERD 224 to be rack-mounted in unmanned facilities and connected to test ports of digital cross-connect switches and matrix switches. Standard Features The T-BERD 224 offers the following standard features and capabilities: ® Auto mode configuration allows the unit to automatically determine the incoming Tl signal’s framing and coding and to configure the T-BERD 224 transmitters and receivers to the appropriate framing format. • A SUMMARY Results Category allows key non-zero and out-of- specification results to be accessed from one results category without having to search through several menus. • Full-duplex drop and insert capabilities enable performance of out-of-service tests in either Tl transmission direction. • Built-in speaker enables the user to monitor VF transmissions in one or both directions. • Traffic analysis provides a simultaneous display of all 24 channel signaling bits for one or both Tl transmission directions. • Multiple side panel interfaces provide full-duplex channel access to external test sets through 2- or 4-wire VF interfaces and a 64 kb/s DSO Interface. • DualTl receivers compatible with DID, D2,D3/D4 (Superframe), ESF (Extended Superframe), and SLC™-96 framing formats provide simultaneous BPV, frame, and CRC error results, as well as received frequency and signal level (in volts peak-to-peak, dBdsx, or dBm) measurements for both Tl inputs. • Timing slip analysis detects differences in system timing between two Tl inputs or between a Tl input and an external reference signal. Gives a visual indication of wander and the potential for frame slips. • Signaling bit control allows users to emulate signaling toward switches, PBXs, and channel banks. • VF signal analysis supplies measurement of a tone’s level and frequency within a VF channel. User-selectable AMI or Bipolar 8-zero substitution (B8ZS). • Error insert capability provides BPV, frame error, and yellow alarm insertion into one of the Tl data streams. • Full-span capability lets the T-BERD 224 replace the CSU or Smart Jack, pass simplex current, and receive signal levels down to -35 dBm. ® RS-232 remote control allows the T-BERD 224 to be used in unmanned central offices, at remote customer premises, and on manufacturing production lines. • All controls and indicators are located on the front panel. Current test set-ups are confirmed at a glance.

This manual provides information about the physical features, functional operation, and specifications of the Telecommunications Techniques Corporation (TTC) T-BERD 224 PCM Analyzer. Basic T-BERD 224 Mainframe information is presented in Sections 1 through 9. Each T-BERD 224 option and its affect upon the T-BERD 224 is discussed separately in Sections 10 through 15. You only need refer to the section(s) for the option(s) installed on your T-BERD 224. For information about the basic T-BERD 224 channel access test set, including initial set-up for testing at a Tl access point, use the T-BERD 224 Mainframe sections that describe basic features and test procedures. For information on what additional capabilities are added by a particular option and how to use them, refer to the appropriate section for that option. Each option’s section includes a description of its affect on front panei switches, connections, and test applications.
