Paradyne 3160-A2-GB21-50 DTE Drop/Insert DSX-1 Interface, Telnet Access, Alarm Message Capability

ACCULINK 316x DSU/CSU

DTE Drop/Insert (DSX-1) Interface

The DTE Drop/Insert interface allows DTEs/PBXs that support the DS1 signal format to share the T1 network with other high-speed equipment. This is available on 2-port and 4-port DSU/CSUs.

Telnet Access

Remote async terminal operations can be performed using Telnet access. Telnet is a Transmission Control Protocol/Internet Protocol (TCP/IP) service that supports a virtual terminal interface.

Alarm Message Capability

The DSU/CSU can be attached, either locally or

remotely, to an ASCII terminal or printer to display or print alarm messages. Alarms can also be displayed on a PC that is using a terminal emulation package.

Front Panel Emulation

The DSU/CSU offers functionality through Front Panel Emulation software that is similar to that provided by the DSU/CSU front panel. The functionality of the front panel is available by clicking on the function keys with the mouse rather than by pressing keys from the actual front panel.

Integral Modem

The standalone DSU/CSUs contain an integral low-speed (2400 bps), V.22bis dial modem that enables communication with remote devices such as another 316x DSU/CSU, an ASCII terminal or printer, or a PC running the 3100 Series Front Panel Emulation software.

Async Terminal Interface Support

The DSU/CSU can be configured and managed from an asynchronous (async) terminal. The async terminal's full screen display uses a menu hierarchy similar to the DSU/CSU's front panel. You can perform device management and configuration operations as if you are using the DSU/CSU's front panel, but you do not have the limitation of the 2-line, 16-character LCD.

SNMP Management Support

SNMP is a network management protocol that is used to monitor network performance and status, and to report alarms (i.e., traps). To function, SNMP requires a manager consisting of a software program housed within a workstation or PC; an agent consisting of a software program housed within a device (e.g., the DSU/CSU); and a Management Information Base (MIB) consisting of a database of managed objects. The DSU/CSU can be managed by any industry-standard SNMP manager.

Two link layer protocols, Point-to-Point Protocol (PPP) and Serial Line Internet Protocol (SLIP), are supported for connection to an external SNMP manager or network device (e.g., a router).

The SNMP manager or network device can be directly connected to the communications (COM) port. An external LAN Adapter can be connected to either the COM port or the auxiliary (AUX) port to provide Ethernet connectivity. Also, the DSU/CSU can be daisy chained together by connecting the COM port of one device to the AUX port of the other, providing SNMP connectivity.

The SNMP management system can communicate to the DSU/CSU remotely through the Facility Data Link (FDL) or (for 2-port and 4-port DSU/CSUs) the synchronous data port's Embedded Data Link (EDL).
