Introduction & Specifications Product Overview
076R172-000 SpectraComm ADT 1-3
Issue 2 Installation and Operation Manual
SC-ADT Interfaces/Connectivity
The typical installation environment for the SC-ADT device is a SpectraComm 5000 shelf,
SpectraComm 2000 shelf, SpectraComm MultiPak enclosure or the SpectraComm 1001/1002
standalone enclosures. In these shelf/enclosure systems, the SC-ADT provides multiple physical
interfaces, described below. The SC-ADT is shipped from the factory with all ports set to
Disabled
except for the modem line port.
Note
Refer to Figure 2-1 for detailed views and information on rear panel connections to the SC-ADT in the
various GDC shelves and enclosures.
Craft Port/Contact Sense
The rear panel DB25 craft port can be used for local configuration and monitoring. This RS-232
interface is fixed as serial async 9600 baud, 8 data, 1 start/stop, no parity. The DB25 connector also
provides the Contact Sense connections.
Ethernet 10/100BASE-TX LAN Ports (Logical E0)
At the shelf/enclosure rear panel, a RJ45 connector provides the Ethernet (LAN) interface for
connecting the SC-ADT to any standard 10/100B-T LAN device, including PCs, servers, hubs and
switches.
Modem Ports (M0 and M1)
The SC-ADT supports up to two external GDC SpectraComm V.34 modems connected to async
Port1 and Port2 for up to two Terminal Emulation (Hyperterm) or Dial-Up Networking (PPP)
sessions. The external modems supply phone line connectivity. For more information about these
external modems (SC V.F 28.8/33.6 or SC V.34 Dual) refer to the associated GDC manuals.
If so equipped, the SC-ADT can provide internal modems that allow Dial-Up connections for up to
two Terminal Emulation (Hyperterm) or Dial-Up Networking (PPP) sessions. At the shelf/
enclosure rear panel, a RJ45 connector provides the modem/line interface for the internal modems.
Terminal Server/Transport Ports (Ports 1 - 32)
The front panel D-type 68-pin connector assemblies provide 16 or 32 8-wire RS-232 terminal server
ports which can connect up to 32 devices simultaneously. If Telnet cut-thru is used, the Telnet ports
2001 - 2032 correspond to Port1 - Port32, respectively, and to Terminal Server menu items. When
ports are configured for transport, async data at any port can be transported to any async port at any
remote SC-ADT location using TCP.
