Precautions
The CAUTION, WARNING, and DANGER statements that appear throughout this manual are
intended to provide critical information for the safety of both the service engineer and operator,and
enhance equipment reliability. The definitions and symbols for such statements comply with ANSI
Z535.2, American National Standard for Environmental and Facility Safety Signs, and ANSI
Z535.4, Product Safety Signs and Labels, issued by the American National Standards Institute.
Safety Guidelines
Under proper conditions, this unit will operate reliably and safely in your network. If any
component is improperly handled or installed, equipment failure or personnel hazard may occur.
Use caution and common sense when installing network wires. Use the following guidelines,
especially when unsafe conditions exist or when potentially hazardous voltages are present:
• Repairs must be performed by qualified service personnel only.
• To reduce the risk of electrical shock, do not operate equipment with the cover removed.
• Never install network jacks in a wet location unless the jack is designed for that location.
• Never touch uninsulated network wires or terminals unless the network line is disconnected
at the network interface.
• Never install network wiring during an electrical storm.
Antistatic Precautions
Electrostatic discharge (ESD) results from the buildup of static electricity and can cause computer
components to fail. ESD occurs when a person whose body contains a static buildup touches a
computer component. This product card may contain static-sensitive components that are easily
damaged. Proper handling, grounding and precautionary ESD measures are essential. Keep parts
and cards in antistatic packaging during transport or when not in use. When handling always use
antistatic floorpads, workbench pads and an antistatic wrist strap connected to a grounded
equipment frame or chassis.
If a wrist strap is not available, periodically touch an unpainted metal surface on the equipment.
Never use a conductive tool, like a screw driver or paper clip to set switches.
CAUTION statements indicate conditions or practices that can cause damage to equipment
or loss of data.
WARNING statements indicate a potentially hazardous situation which, if not avoided,
may result in minor to moderate injury. It may also be used to alert against unsafe practices.
DANGER statements indicate an imminently hazardous situation which, if not avoided, will
result in death or serious injury.

Issue 4 Installation and Operation Manual
Chapter 1: Introduction and
Specifications
Product Overview
The SpectraComm 800 T3 Data Service Unit (SC 800 T3 DSU) provides a flexible and versatile
connection method to T3 telecommunications networks. It converts data from a standard High
Speed Serial Interface (HSSI) port (running from 3 to 44.2 Mbps) to a standard DS-3 port.
Intended Use
The SC800 T3 is a 7-inch by 9.5 inch printed circuit card that supports comprehensive, non-
intrusive network management capabilities, operating inconjunction withan SNMP controller. The
DSU is software-managed so that an operator at a central site can configure its options by means of
SNMP, TELNET or TEAMmanagement. Diagnostictestingperformed through SNMP requires no
intervention by personnel at remote sites.
The SC 800 T3 DSU integrates with a variety of GDC SpectraComm network elements which can
be co-located in a SpectraComm shelf. A SpectraComm 2000 shelf can hold up to two single-slot
product cards, and for high-density applications, the SpectraComm 5000 shelf can hold up to 16
single-slot cards. Shelves fit in 19- and 23-inch wide equipment racks. For non-NEBS standalone
applications, the SpectraComm AC or DC standalone enclosure can hold one SC 800 T3 DSU.
