Product Overview
The SpectraComm Synchronous Data Transport (SC-SDT) is designed primarily for synchronous
data transport for encapsulating packetized, HDLC-based sync data traffic onto Ethernet facilities
over private IP networks. The SC-SDT also performs alarm sensing via contact relays. A future
release will support alarm reporting between locations over the network. SC-SDT provides multi-
level password protection and ethernet access features that enhance the security of the customer’s
network.
Intended Use
The SC-SDT card is a single-width, 7-inch by 9.5-inch (178 mm by 241 mm) printed circuit card
designed for installation in GDC’s “telco-tough” SpectraComm shelves: the two-slot SpectraComm
2000 shelf or the 16-slot SpectraComm/UAS shelf. For remote site or non-NEBS, stand-alone
applications, the same SC-SDT 3-port card installs easily in the single-slot SpectraComm AC or DC
standalone enclosure. Typical shelf configurations can include SC-SDT devices with SpectraComm
routers, switches, modems, DSUs, LTUs and multiplexers.
