Unit of Measurement Converter
ATLAS includes an advanced access architecture for switching dial-up calls to specific ports or DS0s. The Quad Basic Rate ISDN (BRI) Module contains four ISDN U interfaces and combines with other ATLAS 550 components to implement an ISDN access switch. The Quad BRI Module can connect to the ISDN network (NT mode), or it can emulate the ISDN network to other ISDN access devices (LT mode) that support the U Interface, such as terminal adapters and network termination units.
As a component in an ATLAS 550 access switching application, the Quad BRI Module can consolidate multiple Basic Rate ISDN (BRI) connections onto T1/PRI access lines. The module also supports BRI-to-BRI and BRI-to-PRI switching. In addition, the ATLAS 550 can convert between ISDN D channel (PRI or BRI) and T1 robbed bit signaling, allowing non-ISDN equipment to access a more efficient PRI or BRI facility. Moreover, the module's call filtering feature allows you to program on a per-user basis, the call types that will be answered and originated.
The Quad BRI module can be configured through a variety of mechanisms, including Telnet or VT 100 emulation. SNMP management is supported for alarm and event reporting.
The Quad BRI Module includes an extensive array of diagnostic tools to assist in identifying and correcting network problems including a built-in Self-Test utility, local and remote loopback testing for B1, B2, and 2B+D, and performance monitoring to ensure the quality of the ISDN line.
