The Dial Backup capability of the TSU ESP allows for automatic switched backup in the event of a dedicated T1 line failure. The Dial Backup is accomplished through a family of plug-in ESP DBU cards. Several versions of ESP DBU cards are available including 4-wire Switched 56, 2B+D ISDN, and External DCE. When a failure condition occurs on the T1/FT1, the DBU card utilizes the switched network (ISDN, 4-wire Switched 56) or DTR dialing (External DCE) to initiate a call to the remote end.

The Quad T1/PRI module combines with other ATLAS components to implement a variety of WAN access products, including a T1 Bandwidth Manager, an ISDN Access Switch, and a Digital Access Cross-Connect System (DACS). The module provides four network ports, each of which can be independently configured to operate in T1 (DS-1 or DSX-1) or Primary Rate ISDN (PRI) modes. The Quad T1/PRI module can perform T1 to PRI conversion, translating between the robbed-bit signaling presented in a channelized T1 circuit and the D-channel signaling of a PRI circuit. When using the Quad T1/PRI module, ATLAS operates in a DACS mode supporting DS0 time slot interchange and DS0 grooming while preserving robbed bit signaling. ATLAS can be fully populated with Quad T1/PRI modules to support a pure DACSing application of 34 T1 circuits. Configuration of the Quad T1/PRI module can be accomplished through a variety of mechanisms, including Telnet or VT 100 Emulation. SNMP management is supported for alarm an...
