Antenna/amplifier PCS faults

PCS FAULT FINDER from Zetron provides fast notification of power amplifier and antenna problems at PCS sites. The Model Z907 PCS Fault Finder continuously monitors forward RF power and antenna return loss in the 1.8 to 2.0 GHz frequency band. The unit features user-adjustable thresholds that generate an alarm output when forward RF power or antenna return loss falls below the threshold value. Alarm outputs can be integrated with existing PCS site monitoring equipment to report alarm conditions to a central location. Also features in-line measurement with less than 0.2 dB insertion loss, compact dimensions and easy installation, and factory-calibrated fast detector with wide dynamic range.--Zetron, Inc.

Subscriber line kit

HANDHELD TEST INSTRUMENTS from Wandel & Goltermann are designed to analyze all the major parameters of subscriber access circuits quickly and with high accuracy. The Subscriber Line Measuring Kit (SLK) is a complete set of test equipment that offers balanced inputs for measurement on lines for ISDN, PCM, HDSL, SDSL, ADSL, and POTS.

A handy carrying case contains a complete set of subscriber line testers (SLK-11, 12, or 22) and appropriate accessories. The SLK is designed to provide automatic communication between the near-end and far-end instruments. Complete operation of all measurement functions are conducted from one end, which simplifies the procedure and only requires one operator. Upon measurement completion, the instrument provides immediate indication of whether or not the line meets the specified requirements.--Wandel & Goltermann

Now with SS7 over ATM ...

SUPPORT FOR SS7 OVER ATM has been added to the more than 100 protocols and variants already available on the Digital Communications Test System (DCT-S) from Catapult Communications. Catapult's SAAL-NNI Protocol Module allows customers to validate products and services to take advantage of SS7 over ATM applications.

The SAAL-NNI Protocol Module supports SS7 over ATM applications by replacing MTP Layer 2 with the SAAL-NNI protocol stack. This stack provides an adaptation layer specifically for network node signaling, with each sublayer performing specific functions. The system conforms to ITU-T, ANSI, and Belcore ATM specifications.--Catapult Communications
