1. Introduction

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).

Physical Description

The 316x Series consists of a Model 3160 DSU/CSU (2-port), a Model 3164 DSU/DSU (4-port), a Model 3165 DSU/CSU (1-port), and a Model 3161 (carrier-mounted) DSU/CSU.

For more information about the carrier-mounted DSU/CSU, refer to the ACCULINK 3151 CSU and 3161 DSU/CSU General Information Guide and the COMSPHERE 3000 Series Carrier Installation Manual.
