The ADTRAN® DSU IV ESP™ is an all-rate data service/channel service unit (DSU/CSU) with an integral SNMP (simple network management protocol) agent and optional dial backup (DBU) capabilities. It provides an interface between digital data service (DDS) or 4-wire Switched 56 and the cus- tomer’s data terminal equipment (DTE). The DSU IV ESP provides access to traditional dedicated point- to-point,multi-point, or Frame Relay services.

The unit supports synchronous (2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64 Kbps) and asynchro- nous (2.4, 4.8, 9.6, 19.2, 38.4, and 57.6 Kbps) data rates. Both EIA-232 and V.35 physical interfaces are provided for connection to the customer’s DTE equipment.

Embedded SNMP and Telnet are available through SLIP (serial line internet protocol) or PPP (point to point protocol) using the integrated control port or through an optional 10BaseT ethernet port when configured with the plug-in ESP ethernet card. Through the Management Information Base (MIB)-II standard and an ADTRAN-supplied enterprise MIB, the DSU IV ESP can be configured, monitored, and diagnosed using standard SNMP network management programs such as HP OpenView®, Netview®, and SunNet® Manager.

The Dial Backup (DBU) feature of the DSU IV ESP allows automatic or manual switched backup in the event of a dedicated line failure. The addition of DBU is accomplished through a family of plug-in ESP DBU cards. There are three versions of ESP DBU cards available for the DSU IV ESP: ISDN,

4-wire Switched 56, and V.34 analog (max.

33.6Kbps). Upon recognition of a failure(s), the unit connects to the remote end using the switched network. The user can choose whether the unit automatically or manually reverts to the dedicated circuit when it is restored. Optional weekend and time of day DBU lockout options are provided.

The unit responds to standard loopback commands from the telephone company central office. In addition, there are several built-in test capabilities. Complete control, configuration, and diagnosis are available through a 16-key keypad and a two-line by

16-character LCD display. A VT100 terminal configuration and control mode is also avail- able through the control port. Flash download capability allows for quick and easy installa- tion of new features and enhancements.
