Arcareach Sigma -
Arcatech Limited
Arcareach | Sigma is an inverse NT-1 that changes an S interface (NT side) into a U interface (LT side) and provides power feeding (70V) on the U interface. Many digital PBXs offer ISDN S-bus interfaces as standard which can operate up to 0.9km (3000ft) under certain conditions. When there is a requirement for the S-bus to be located much further from the PBX the Arcareach | Sigma can be used to turn the S-bus interface into a U interface, supporting 2B1Q encoding.

Tempo Communications, Inc.
There are times when using a conventional test telephone or other device to check whether a line is "dead" before cutting it down just won't work. One example is where a cable can be carrying an "out-of-band" service, like ADSL and VDSL, which are inaudible using conventional monitoring equipment. T-Bug will specifically identify the nature of the service on a line, whether xDSL or ISDN, while the DigAlert™ probe will warn if any high frequency signal is present. Check before you cut.

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.
