Introduction

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.
Asynchronous Terminal Interface Support
The DSU/CSU can be configured and managed from an asynchronous (async)
terminal. The asynchronous terminal’s full screen display uses a menu hierarchy
to perform device-control operations.
Chapter 3, Operation , provides operational examples to help you become familiar
with the use of the asynchronous terminal for DSU/CSU control.
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.
Chapter 5, Monitoring and Testing , provides a list of alarm messages.
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.
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 or can be accessed via Ethernet using the 10BaseT
port.
The SNMP management system can communicate to the DSU/CSU remotely
through the Facility Data Link (FDL) or the synchronous data port’s Embedded
Data Link (EDL).
