ACCULINK 316x DSU/CSU

SNMP is an industry-standard network management system 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; an agent consisting of a software program housed within a device (e.g., 3160/3164 DSU/CSU); and a MIB consisting of a database of managed objects, accessible to agents and controlled via SNMP, to provide network management information.

The 3160/3164 DSU/CSU supports a MIB that can be accessed using SNMP protocol by external SNMP managers. The following MIBs are supported:

•MIB II ± Defines the general objects for use with a network management protocol in TCP/IP internets and provides general information about the DSU/CSU. MIB II is backward-compatible with MIB I.

•DS1/E1 MIB ± Defines objects for managing DS1 interfaces and supports the network and DTE drop/insert T1 interfaces.

•RS-232-like MIB ± Defines objects for managing RS-232 type interfaces (e.g., RS-422, RS-423, etc.) and supports synchronous data ports and management communication ports on the DSU/CSU.

•Generic-Interface MIB Extensions ± An extension to MIB II that defines additional objects for control of generic interfaces in MIB II. It supports control of tests on the DSU/CSU's T1 and synchronous data interfaces that are not supported by other MIBs.

Two link layer protocols are supported for connection to an external SNMP manager or network device, Point-to-Point Protocol (PPP) and Serial Line Internet Protocol (SLIP). The protocol type is configurable using the configuration options (see Appendix C, Configuration Options).

Communication with the external SNMP management system can be through a serial connection on either the COM port or the MODEM port. Only one port can be configured as the management link at one time. However, the 3160/3164 DSU/CSU can be accessed simultaneously by either the front panel or front panel emulation software on one port, and an SNMP management system on the other port. Users on the external SNMP manager can issue ªGetº and ªSetº SNMP commands to an object in the SNMP database maintained by the DSU/CSU. The DSU/CSU can be configured to issue SNMP traps to the SNMP manager under various alarm conditions.

ACCULINK 316x DSU/CSU Physical Description

The ACCULINK 316x DSU/CSU series of products consists of a standalone 2-port Model 3160 DSU/CSU, a standalone 4-port Model 3164 DSU/CSU and a 2-port carrier-mounted Model 3161 DSU/CSU.

Standalone Model 3160/3164 DSU/CSUs

The 3160/3164 DSU/CSUs are housed in a compact, standalone unit containing a front panel for control and monitoring of the DSU/CSU and a rear panel for connections. This standalone unit can be mounted on a wall, an equipment shelf, or an RS-310-C equipment cabinet with the optional wall-mount kit.

3160/3164 DSU/CSU Front Panel

The 3160/3164 DSU/CSU front panel contains,

•One 2-line, 16-alphanumeric character per line liquid crystal display (LCD)

•One 7-button keypad (three Function and four directional keys)

•Twelve light-emitting diodes (LEDs), five of which are shared between the DSX-1 (DTE) Drop/Insert T1 interface and the data ports.

•Six test jacks

The front panel is shown in Figure 1-1.

3160/3164 DSU/CSU Rear Panel

The 3160/3164 DSU/CSU rear panel contains the connectors required for the operation of the DSU/CSU (Figures 1-3 and 1-4). The connectors and their functions are listed in Table 1-1.
