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 in conjunction with an 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 TEAM management. Diagnostic testing performed 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.
