Modular Digital Exchange with ISDN (MDX•I)
The Modular Digital Exchange with ISDN (MDX•I) is a powerful telecommunications switching system ideal for public exchange switching including end office, tandem office, and international gateways. The RUS-accepted MDX•I has a patented distributed architecture which provides a versatile platform for managing complex communications in a variety of public network applications. The MDX•I is a tough and rugged public exchange ideally suited for harsh environments.
The MDX•I control package has dynamic system software and administrative capabilities. This allows it to be configured for a variety of applications including wireless and wireline, network integration, and emergency rapid response capabilities.
The MDX•I is available for Competitive Local Exchange Carriers (CLECs) and Multi-Tenant Systems and can be custom engineered for these markets. Your package can include all necessary components: switching platform, voice mail, battery back-up, and an advanced set of calling features in one convenient package.
Select MDX•I Features - Communications Assistance Law Enforcement Act (CALEA) support provides sophisticated call monitoring and electronic surveillance capabilities engineered to meet ANSI-J-STD-025-A.
- Expanded Digital Announcer is a powerful digital announcer that provides both CLASSSM and intercept announcements.
- SS7/C7 Connectivity engineered to industry standards and protocols.
- Emergency Response Systems are packaged in a portable, shock-absorbent container (rack-pack) that can be transported to the emergency site and made operational within hours.
- Computer Telephony Integration (CTI) Link allows a host computer to assert call control commands in response to MDX•I port/state messages. This link allows the MDX•I owner to develop custom applications, including line and trunk protocols.
- ClusterNet™ Technology allows true unification of multiple MDX•I sites, or a single MDX•I site to have multiple, strategic equipment locales. ClusterNet™ allows users to enjoy the unparalleled reliability of a fully distributed system, yet also enjoy the convenience of centralized administration.
- End Office with full-featured metropolitan capabilities, including CLASSSM features, subscriber custom calling features, LAMA/CAMA reporting, and a call translator with completely flexible dialing plans.
- Public Exchange Adjunct Systems allow the MDX•I to work as a tandem switch for public service providers to offer ISDN services and other revenue-generating features with minimal impact to existing hardware.
- ISDN Primary Rate Interface supports protocols at both the network and user ends.
- ISDN Basic Rate Interface (2B+D) supports network end interface protocols for 2-wire U interfaces and 4-wire S interfaces.
