Introduction & Specifications Product Overview
076R174-000 SpectraComm SDT 1-3
Issue 4 Installation and Operation Manual
SC-SDT Interfaces/Connectivity
The typical installation environment for the SC-SDT device is a SpectraComm 5000/UAS shelf,
SpectraComm 2000 shelf, or any model of the SpectraComm standalone enclosures. In these shelf/
enclosure systems, the SC-SDT provides multiple physical interfaces, described below. The SC-
SDT is shipped from the factory with all ports set to Disabled.
Note Refer to Figure2-1for detailed views and information on rear panel connections to the SC-SDT in the various
GDC shelves and enclosures.
Craft Port/Contact Sense
The rear panel DB25 RS-232 craft interface supports contact sense connections. It also supports
local configuration and monitoring via fixed serial async 9600 baud, 8 data, 1 start/stop, no parity.
Ethernet 10/100BASE-TX LAN Ports (Logical E0)
A rear panel RJ45 connector provides the Ethernet (LAN) interface for connecting the SC-SDT to
any standard 10/100B-T LAN device, including PCs, servers, hubs and switches.
Transport Ports
Three high density 26-pin “smart” serial connectors provide the front panel DTE or DCE interface
for packetized, HDLC-based synchronized data transport. Six serial interfaces are supported: EIA/
TIA-232, EIA/TIA-449, X.21 and V.35 in both DTE and DCE modes; and EIA530 or EIA530A in
DTE mode only.
Diagnostics and Statistics
• Generates/answers pings
• Tests Contact States
• Transmit and Receive packet counts on Ethernet interface
• Transmit and Receive byte counts on Ethernet interface
• Transmit and Receive packet and byte counts on Sync ports
Throughput Performance
Typical Throughput Conditions
It is expected that the traffic patterns of typical applications will be bursty in nature, thereby
allowing all three sync ports to deliver data without loss under typical traffic conditions
Application (Protocol) Flow Control
It is expected that the customer's end-devices provide a flow control mechanism at the application
level. Some example applications (or protocols) that provide this capability are FTP and X.25.
These end applications will hold-off data transmission to avoid traffic loss while maximizing
throughput across the network.
Worst-case Throughput Conditions
Duringextreme traffic conditions,theSC-SDTwillhandleanaggregaterateof 3Mbps,fullduplex.
This translates to 1Mbps per port if using all three ports under worst-case conditions.
Note Extreme traffic conditions are defined as continuous sync data (i.e. non-bursty) with application flow-control
required.

Introduction & Specifications Product Overview
1-4 SpectraComm SDT 076R174-000
Installation and Operation Manual Issue 4
SC-SDT Security
SC-SDT devices are multi-level password-protected and also provide inactivity timers. For periods
of heightened security, authorized users can configure access controls to filter out specific
protocols, such as HTTP, SNMP and/or TFTP access to the unit.
Management
Smart CLI Management
The SC-SDT employs an interactive command line interface that will feel familiar to most field
personnel. Added features include auto-prompting for command arguments, recognition of
abbreviated commands, online help, command line recall and an advanced utility for generating
downloadable ASCII configuration files.
Telnet Management
The SC-SDT provides password-protected Telnet access from anywhere in the network via
Ethernet LAN connection at the rear panel. A customer-supplied router is required at the SC-SDT
location.
Web Management
The SC-SDT supports direct password-protected web management via HTTP for internet-ready
network monitoring. An embedded web server agent allows Read or Read-Write access to the SC-
SDT using popular browsers. To enhance security, the SC-SDT supports web time-outs and
password-protected access over the web interface. HTTP services can also be disabled to block web
access to SC-SDT devices.
SNMP Management
An embedded SNMP agent allows discovery by the SpectraComm Manager (SCM) card, retrieval
of statistics, and alarm traps, and supports SNMP MIB-2 (RFC1213). SNMP access can be disabled
to avoid hacks during intervals of heightened security.
Note SNMP support does not require a SpectraComm Manager (SCM) co-located in the shelf with the SC-SDT.
TEAM Management (Future Release)
A future release of the SC-SDT will support auto-discovery and polling by GDCs TEAM software
(Total Enterprise Access Management). TEAM uses HPOV APIs (Application Programmer
Interfaces) to integrate with HP OpenView Windows and other network management applications.
The SC-SDT will also be able to launch a direct Telnet or web-based CLI session from the map
window. For more information on the availability and operation of these additional features, refer
to later issues of this document or contact your GDC Sales Representative.
Note TEAM support requires an SCM card at version 5.80 or greater and co-located in the shelf with the SC-SDT.
For more information, refer to the GDC TEAM Core documentation and Release Notes.

A Transport Applications
The synchronous transport application of the SC-SDT links equipment together over thecustomer's
IP network. The SC-SDT encapsulates the packetized, HDLC-based sync traffic and forwards the
data over Ethernet using TCP/IP. The sync data at any local SC-SDT port can be forwarded to any
sync port at any remote SC-SDT location.
Each SC-SDT front panel connector allows connection with up to threelocalsynchronous customer
equipment ports. For higher density requirements, simply add more SC-SDT devices to the ethernet
segment at each site. When the user connects the “smart” serial cable, SC-SDT will auto-configure
the interface settings (e.g., V.35 or RS232) and the device type (DTE or DCE). A DTE-type port
will receive clocking from the local equipment. A DCE-type port will provide clocking to the local
equipment.
Figure1-3showsmultiple siteswithsyncequipment linkedtogetheroverthecustomer's IP network

A Contact Sense Applications
The SpectraComm SDT rear panel DB-25 connector can perform contact sensing and can be
configured for alarm notification whenever a change in contact relays occur at customer sites.
SC-SDT detects when a contact changes from its normal state and declares an “active” alarm.
A “clear” trap is sent when the contact returns to the normal state. The alarm notification is user-
configured to send an SNMP Trap as follows: after sensing a relay state change from the normal
state (open or closed), an alarm trap is sent to a management station using an SNMP alarm trap.
Each SC-SDT rear panel connector provides up to eight contact input ports for sensing activation
of an open or closed contact. To support requirements for more contact ports, simply add more
SC-SDT devices to accommodate each site requirements.
Figure 1-4 shows the SC-SDT tracking temperature and entry sensors at a remote location, with
SNMP Traps sent to a Management Station. Contact transport message (future option) is shown
being sent to another SC-SDT site.
Note An SC-SDT is not needed to receive traps. Any Management Station in the network can be a trap destination.
Figure 1-4 Contact Sensing with Contact Alarms (Contact Transport shown as future option)
Future Options
• Contact State Transport (Future option): After sensing a relay state change, a message is sent
to a remote SC-SDT devicetoopen or close a relay at that site.SC-SDTdevices will be required
at both sites.
• TrapandTransport(Futureoption):The alarm will be transported between sitesand aTrap will
be sent to a management station (destinations for alarm transport and Trap are independent).

Chapter 2: Installation & Connections
Overview
This chapter describes installation procedures for the SC-SDT Synchronous Data Transport device
as well as making power connections, performing pre-operational checks, and making system
connections. If this is your first installation of the SC-SDT, be sure to read the previous sections of
this manual to understand the optimal functioning of the SC-SDT product as it applies to your
network.
Shelf / Enclosure Installation Guidelines
• Locate the SpectraComm shelf in a ventilated area where the ambient temperature does not
exceed environmental specifications (Table 1-2).
• Do not install the shelf directly above equipment such as power supplies, which generate large
amounts of heat.
• When SC-SDT devices are to be installed in the SC 2000 shelf, do not wall-mount the shelf
vertically as no strain relief is available to the front panel connector assemblies in this position.
SpectraComm SDT Installation Guidelines
• In high density applications the SC-SDT device can be installed in a single slot of the 16-slot
SpectraComm/UAS shelf. In low density applications, the device can be installed in the two-
slot SpectraComm (SC2000) shelf or the single-slot SpectraComm AC or DC standalone
enclosure.
• Perform the setups, connections, and pre-operation checks in their entirety, as described in this
chapter.
Note For more information on any SpectraComm shelf or enclosure, refer to associated manuals listed on the
inside front cover of this document and provided on the GDC Publications CD.
