Introduction and Specifications
CSU/DSU Functionality
The SC-IP contains an integrated CSU/DSU. Users can access digital services at T1/FT1 rates
through the network interface. The Network interface provides all N x 56/64 Kbps rates from
56kbps to 1.536 Mbps (where N=1 to 24) and supports both DS1 and DSX-1.
Smart CLI
The SC-IP 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.
Web Management
The SC-IP provides internet-ready network management (HTML and JAVA 1.1 support). An
embedded web server agent allows Read or Read-Write access to SC-IP using popular browsers.
SC-IP Interfaces/Connectivity
The typical installation environment for the SC-IP card is a SpectraComm 5000 or 2000 shelf.
SC-IP has multiple physical interfaces, described below. The unit is shipped from the factory with
all ports set to Disabled except for the Modem port and the AUX port.
Craft (Console) Port
The Craft port is used for local configuration and monitoring. This EIA-232 interface is fixed as
serial async 9600 baud, 8 data, 1 start/stop, no parity.
Ethernet (10/100BASE-T) LAN Ports
The two Ethernet (LAN) ports allows the SC-IP to connect directly to a computer's LAN port, or
to a hub device or external ethernet switch for connection to many LAN devices. With the SC-ES
card co-located in the shelf, the SC-IP can access more equipment on LANs using 10BASE-T or
100BASE-T (twisted pair) wiring while maintaining NEBS compliance.
T1/FT1 (Network) Port
The SC-IP provides an integral, fully managed Full T1or Fractional T1 CSU/DSU with Frame
Relay UNI-U and PPP support.
Terminal Server Ports
Eight, 3-wire RS-232 ports connect up to eight devices (one port active at a time).
Future Upgrades
Asynchronous AUX/Synchronous DTE Port
This port is designed to accommodate two types of interfaces. The synchronous DTE (EIA-232)
interface can operate up to 64 kbps (max) and is used to connect directly to a SC 521A device for
DDS network connections (external timing is not supported.) The asynchronous AUX (EIA 232)
interface is used for connection to an external modem.
V.90/V.34 Modem Port
The modem port is designed to accept dial-up connections for direct VT-100 access (Hyperterm) or
PPP session.
Note
For configuration of SC-IP interfaces, refer to Chapter 2: Installation and Set-Up.
