Patton Electronics Co.
A Media Gateway is a networking device that provides valuable and essential functions for organizations, service providers, and network operators. When interconnecting traditional time-division-multiplexed (TDM) telephony systems with modern voice-over-internet protocol (VoIP) systems, a VoIP media gateway works by providing protocol conversion (translation) and interoperability between the two network technologies. Also known as an IP media gateway or SIP media gateway, the device converts a traditional analog plain-old-telephone-system (POTS) voice signal or related digital telephony signals such as T1, DS3, STM1 or OC3 into packets for transmission over a data network such as the Internet, private IP Network or a corporate LAN. When the legacy system is based on digital integrated services digital network (ISDN) technology, the device may be called a digital VoIP gateway or ISDN media gateway. Some manufacturers combine gateway functionality with WAN-access (internet-access) capability into a single device or network appliance. Such a dual-purpose device may be known as an access media gateway.

VOIP Echo -
GL Communications Inc.
*The Voice Band Analyzer (VBA) is an analysis tool for monitoring the quality of voice band traffic (including hybrid echo) over VoIP, TDM and wireless networks*VBA works in conjunction with GL's TDM, Packet, and Wireless non-intrusive capture products, such as T1 and E1 Call Capture and Analysis, VoIP PacketScan&trade, and GSM, CDMA, and 3G Call Capture Products. VBA instantly detects voice file captures and with appropriately installed analysis modules, monitors speech levels, noise levels, and hybrid echo. Other analysis modules such as ITU-T P.561, P.562, P.563, fax and modem analysis, and many others can be hosted as plug-ins.*The VBA application can also operate on pre-captured files. It supports A-Law, µ-Law, 16-bit PCM (Intel), 16-bit PCM (Motorola) and MS Wave file formats.*Required software PKV100 and VBA032 at each probe location and PKV170 PacketScanWEB - Network Surveillance Software*Required hardware - 1U rack PC with sufficient hard disk for capturing over 10,000 calls (80 GB HD) for each VBA colocated with a probe*Additional hardware - PC for PKV100 PacketScan™ Software

E1 & T1, Data, DSL, Protocols, BER Analyzers -
GAO Tek Inc.
With 20 years of experience in the development and production of test instruments, GAOTek is proud to provide a large selection of PSTN analyzers that meet the requirements of technicians working in the telecom industry for sale to the United States, Canada and Globally. Public Switched Telephone Network (PSTN) was designed to ease the two-way communication between two points or two users. In the beginning, a direct connection between two points was very simple, however the cost was too high depending on the distance and geography. The network engineers revolutionized voice communications by creating PSTN which is still in use today.

Berry Test Sets
The BE9000 is a portable AC powered test set for use at almost any point in a circuit on the customer premises location (PBX or station equipment) to the Central Office. The BE9000 is able to accommodate a wide range of circuit types such as: DS1, DS0, DDS and all 2Wire or 4 Wire analog Special Circuits. Maintenance and installation of these circuits requires a combination of these functions: DS1 performance monitoring, DS1 BERT, DS0 BERT, Drop & Insert, Transmission, Signaling, Ringing, Addressing and Supervision in one test set to achieve maximum technician efficiency. Additionally, the set can be programmed in the field so that repetitive tests can be stored and recalled for future use.
