Description features of 635A Connects to PC via serial Ability to print Battery Charging Status (Displayed on front) At a Glance Full featured, handheld T1 test set at an affordable price Instantaneous detection and display of framing, line coding, errors, alarms, level, frequency and more Transmits and receives common Bit Error Rate Test (BERT) patterns and includes all common loop codes, including HDSL Product Capabilities In a single 4 lb (1.8 kg) package, the 635 includes all the basic T1 testing capabilities you would expect in a larger and more expensive tester. It performs bit-error tests, detects framing type, line coding and bit pattern, and displays signal level, frequency, clock slips, errors and alarms. The 635 transmits the most commonly used loop codes, including HDSL. Full, unframed and fractional (56k and 64k) T1 are supported, along with display of signaling and data bits and capture of DTMF digits. Plus, individual voice channels may be monitored on the built-in speaker or over a headset. Eleven standard BERT patterns are available, including a 64-bit user-defined pattern. The 635 also includes a "through" mode where the incoming pattern is retransmitted. Errors - including bipolar violations, logic and frame bit - can be injected to confirm proper handling by the network. Two receivers permit detection of any clock slips. Multiple receiver input types allow terminated, bridged or monitor (DSX) connections. Either recovered or internal clock references can be selected. AMI or B8ZS line coding can be transmitted and received, and SF, ESF, SLC96 and unframed framing are supported. The 635 is compact, rugged and easy to use. Just plug it in and you can immediately see essential information without scrolling through layers of menus. The 635 automatically detects framing and line coding type and instantly displays any errors or alarms. A history indicator helps track intermittent problems. Fluke 635 Features Transmits all standard T1 BERT patterns and loop codes Transmits HDSL loop codes Has the ability to insert logic, BPV, and frame bit errors Automatically syncs to and displays framing type, line coding, and BERT pattern Performs BERT and Fractional T1 BERT (Nx56 and Nx64) Captures and displays DTMF digits Measures DS1 frequency, level, and clock slips Displays standard T1 alarms and major T1 performance parameters Displays AMI or B8ZS line coding Monitors voice, DS0 frequency and level, and DS0 signaling and data bits Prints test results and setup information Fast, automatic testing The Fluke Networks QuickBERT-T1 test set makes quick and easy work of T1 facility verification and troubleshooting. Plug in this tester and instantly get essential information including framing type, line coding, BERT pattern, T1 signaling and frame synchronization status, alarm conditions, density violations, and framing loss. Error conditions are also automatically displayed such as: bipolar violations, frame bit errors, CRC errors (ESF), and bit errors in a received BERT pattern. For long-term testing, history status is provided to indicate intermittent problem conditions. And for further analysis, test results can be printed. The QuickBERT-T1 gives you fast, in-depth test features without time lost in configuring the test or remembering setups and menus. The lightweight, rugged design makes this handheld instrument easy to use in any location. Complete T1 BERT Set The QuickBERT-T1 verifies bit error performance, frequency, and level of the DS1; signaling and VF performance of the individual DS0s; and general T1 performance parameters. A full-range primary T1 receiver is provided for testing low-level signals. A secondary reference receiver is also available for analysis of network synchronization and timing. Ten common BERT patterns are provided with the unit, as well as a user-selectable 64-bit pattern that may be customized. The QuickBERT-T1 can also be used in a Thru mode which allows you to transmit the Rx signal back out the Tx jack. The QuickBERT-T1 is equipped with a T1 transmitter. If significant problems have developed, an out-of-service BERT may be necessary. BERT or Fractional T1 BERT may be performed by simply connecting the unit to the facility, transmitting the appropriate loop code, and selecting a pattern. The QuickBERTT1 does the rest. Decodes and displays signaling and data bits For individual channels, the QuickBERT-T1 decodes and displays signaling and data bits associated with each of the 24 DS0s. The audio quality of the channel is quickly determined via the internal speaker or external headset. If more precise analog measurements are necessary, the frequency and level of a tone present on a channel can be displayed on the LCD screen. Independently transmits and receives The transmitter of the QuickBERT-T1 is independent from the signal on the receiver, allowing you to transmit one BERT pattern while receiving another. Tests at any point in the span For in-service testing, the QuickBERT-T1 is equipped with a full-range primary receiver, which allows use at any access point on the T1 facility (e.g., monitor jack or bridge access point). The test set determines the level and frequency of the T1 signal. For outof- service testing, it may also be used to terminate a T1 span. Solves timing problems Timing is one of the most common sources of error within a T1 network. The QuickBERTT1 contains a secondary reference receiver for use in measuring clock slips. When a signal is present on both the primary and secondary receivers, the test set registers and displays the timing differential between the two clocks. If clock synchronization is causing the problem, it can be readily determined and isolated without additional test equipment. The reference receiver in the QuickBERT-T1 may also be used for an external precision transmit clock source.
