The Drop and Insert (D&I) Module provides a secondary T1 (1.544 Mbps) interface to telco or to private T1 facilities. By adding the D&I Module to a TSU Multiplexer, the user has the capability to support two independent T1s for data, voice, or video, eliminating the need for a second multiplexer. The module provides the capability to selectively insert and extract channels between the primary T1 interface on the TSU Multiplexer and the secondary T1 interface on the module. This allows for the connectivity of two remote sites through a central site. The module operates with either AMI/B8ZS coding or D4/ESF framing. For easy configuration, the D&I Module options are programmed using the front panel, a VT 100 terminal interface or the optional Windows-based T-Watch PRO software. The module can be configured remotely via the FDL (ESF circuits only) when attached to a local TSU multiplexer using T-Watch PRO. The TSU, TSU LT, TSU ESP, TSU 100, TSU 120, TSU 600 and TDU 120e are intelligent, full-featured T1 DSU/CSUs, designed to interface customer DTE to T1 or Fractional T1 services. These devices can be used to terminate the far end of the D&I T1 circuit. The Drop & Insert Module is one of many application-specific modules available for the TSU Multiplexer. The ability to combine different expansion modules with plug-on units provides a variety of interface port combinations for voice, data, dial backup and video applications.

The Quad Universal Synchronous Serial Interface (USSI) module combines with other ATLAS components to provide solutions for a variety of wide area networking applications. Providing four synchronous EIA-530, EIA-530A, X.21, (V.11), V.36, RS-449 or RS-232 DTE ports, the Quad USSI module serves as the interface for high-speed routers and other DTE equipment to access the wide area network. Each port of the Quad USSI module can be configured through software to operate at any multiple of 56 or 64 kbps, up to 2.048 Mbps.Using the ATLAS Channel Mapping Utility, a port can be mapped to one or more DS0s of a T1 or T3 circuit, providing high performance connections to remote locations. For switched access applications, ATLAS can be configured to route calls between the Quad USSI module and ISDN (Basic Rate or Primary Rate) circuits. As with all ATLAS components, configuration can be accomplished through a variety of mechanisms, including Telnet or VT 100 emulation. SNMP management is supported for alarm and event reporting. The Quad USSI module supports an 8, 000 bps in-band management channel to communicate with remote ADTRAN TSU devices. This channel is available full-time for sending management information between devices. The Quad USSI module includes an extensive array of diagnostic tools, to assist in identifying and correcting network problems. Included is a built-in Self-Test utility, as well as standards-based 511 test pattern generators and detectors for each of the four ports. Key interface signals from each of the four ports are monitored and displayed, providing real time status of network activity.

When your application requires an EIA-530 or EIA-449 interface, the Nx56/64 EIA-530 (expansion) Module should be selected. Available as a plug-in module only, the EIA-530 (expansion) Module provides a single, female DB-25 interface which can be adapted to EIA-449 (user supplied cable). For future expansion, the Nx56/64 EIA-530 expansion Module accepts most plug-on modules. This module is suitable for router, audio systems, video systems and switches that require a synchronous EIA-530 or EIA-449 DTE interface.

The Async-232 Module combines with other ATLAS components to provide solutions for a variety of wide area networking (WAN) applications. Providing sixteen asynchronous EIA-232 data terminal equipment (DTE) ports, the Async-232 Module serves as the interface to terminal servers and other DTE equipment. Each port of the Async-232 Module can be configured to operate at any standard asynchronous rate up to 115.2 kbps. For remote access applications, ATLAS receives incoming analog or ISDN-based signals from remote users, and concentrates them onto T1 or Primary Rate ISDN (PRI) circuits. These calls are then processed and directed to the Async-232 Module via the ATLAS internal bussing system. As with all ATLAS components, the Async-232 Module can be configured through a variety of mechanisms including Telnet or VT 100 emulation. In addition, SNMP management is supported for alarm and event reporting.
