Paradyne 316x manual Features, Integral Modem, User Interface, Alarm Interface

ACCULINK 316x DSU/CSU

•Independently selectable DTE interfaces (V.35, EIA-530A, V.11, and/or RS449/422).

•Flexible timing source, available from the

T1 network interface, the DSX-1 T1 interface, at least one of the synchronous DCE data ports, an internal clock, or an external clock.

•Flexible, user-friendly channel allocation.

The 3160/3164 DSU/CSUs are available in a compact standalone case (Figure 1-1) that can be mounted on a desktop, shelf, or wall. The 3161 DSU/CSU is available as a circuit card that is installed into a COMSPHERE 3000 Series Carrier.

Features

The 316x DSU/CSU offers a wide variety of features:

•Integral modem for 3160/3164 DSU/CSUs only which enables remote operation to enhance serviceability and increases uptime.

•User interfaces for access to configuration and alarm information.

•Front Panel Emulation via Windowst-based front panel emulation software.

•Front panel pass-through to access a remote 3160/3164 DSU/CSU.

•Async terminal interface support.

•DSX-1 Drop/Insert port.

•Front Panel Access Control feature.

•SNMP Management Support.

Integral Modem

The 3160/3164 DSU/CSUs contain an integral modem that enables communication with remote devices such as another 316x DSU/CSU, or an ASCII terminal or printer. This is a low-speed (2400 bps), V.22bis dial modem that provides remote dial-up capability to support downloading, pass-through, alarm reporting, and remote configuration and diagnostics. The integral modem can also communicate with a PC running the 3100 Series Front Panel Emulation software accompanying the 316x DSU/CSU.

User Interface

There are three ways of accessing the user interface:

•Front panel ± provides an LCD and a keypad which enable you to display information about and interact with the DSU/CSU. A menu tree is available which enables control of the DSU/CSU in the network (see Appendix A, Front Panel Menu).

•COM Port ± used for 3100 Series Front Panel Emulation software which displays the DSU/CSU front panel on a PC and provides the same functions as the actual front panel. It is also used for the async terminal connection (3160/3164 only). For Model 3161 DSU/CSUs, only one slot in the carrier can be configured as the COM port; all slots share the PC.

•MODEM Port ± provides 3160/3164 DSU/CSU functionality from a PC attached either remotely or by using pass-through via another DSU/CSU (3160/3164 only). It is also used for the async terminal connection. This port is located only on 3160/3164 DSU/CSUs.

Alarm Interface

The 3160/3164 DSU/CSU can be attached, either locally or remotely, to an ASCII terminal or printer to display/print alarm messages. The COM and MODEM ports can be used as destinations for Alarm Set and Alarm Clear messages. This enables an ASCII terminal/printer or async terminal to be used to monitor the DSU/CSU for alarm conditions, but provides a potential conflict if the COM or MODEM port is also the current active physical interface. If this occurs, the user interface functions have priority over any alarm messages that are sent to the currently active physical interface.

Alarms can also be displayed on a PC that is using a terminal emulation package.

Model 3160/3164 DSU/CSUs can be configured to generate traps on alarms which can be sent to an SNMP manager via either the MODEM or COM port.
