Installation and Operation Manual
SCIP Interfaces/Connectivity
SCIP devices install in the SpectraComm 5000 shelf, the SpectraComm 2000 shelf, or a SpectraComm
standalone enclosure. SCIP has multiple physical interfaces, described below. The unit is shipped from
the factory with all ports
Disabled
except for the Modem and AUX.
Note
In router mode of operation, both serial ports (S0 and S1) may be enabled simultaneously. In LAN-X mode
of operation, only one of the serial ports (S0 or S1) may be enabled; the other must be disabled.
Craft (Console) Port
The front panel craft port is used for local configuration and monitoring. This RS-232 interface is
fixed as serial async 9600 baud, 8 data, 1 start/stop, no parity.
Contact Sense
The rear panel DB25 connector can provide up to eight input connections to external dry contact
devices. The SCIP polls input connections very rapidly, providing simultaneous contact sensing,
SNMP traps and log entries for all configured ports. The rear panel DB25 connector allows
simultaneous connectivity for local managment and contact sense functions via the DB25M-to-
wirewrap cable (
).
Ethernet 10/100BASE-TX LAN Ports (Logical E0)
SCIP’s two front panel Ethernet (LAN) ports allow a direct connection to a computer’s LAN port,
or to hub device or external ethernet switch for connection to many LAN devices. LAN ports are
hard-set to enable flow control, and to auto-negotiate port speed (10 or 100Mbps) and duplex mode
(full or half). Auto-MDIX is not supported. With a co-located SC-ES card, SCIP can access more
LAN equipment on LANs using 10BASE-T or 100BASE-T (twisted pair) wiring while maintaining
NEBS compliance.
T1/FT1 Network Port (Logical S0)
The rear panel upper 8-pin modular connector provides the integral, fully managed Full T1or
Fractional T1 CSU/DSU interface, supporting N x 56/64Kbps rates from 56Kbps to 1.536 Mbps
(where N = 1 to 24). The WAN protocols supported on this interface are Frame Relay UNI-U, PPP
and LAN-X.
Modem Port (Logical M0)
The rear panel upper 8-pin modular connector provides the modem’s V.34 interface (dial-up
connections) for direct VT-100 access (Hyperterm) or PPP sessions.
Terminal Server Ports (Term1 - Term8)
The rear panel DB25 connector and adapter provides the eight, 3-wire RS-232 ports which connect
up to eight devices (one port active at a time). If Telnet cut-thru is used, the Telnet ports 2001 - 2008
correspond to Port1 - Port8, respectively, and to Terminal Server menu items. With SSH enabled,
(Secure Shell), Telnet ports are 3001 - 3008.
Note
Terminal server ports are not available when the Contact Sense function is in use.
Synch/Async Port
Synchronous DTE Interface (Logical S1)
The rear panel lower 8-pin modular connector provides the synchronous DTE (RS-232) interface
which connects to a separate SC 521A or UAS 611 DSU device in the shelf for DDS network
connections. This port gets timing from the connected DSU and supports data rates up to 128Kbps
at short cable lengths. To compensate for transmit clocking problems at high rates and long cables,
the port is configurable for normal or inverted transmit clocking (external timing is not supported).
Asynchronous AUX Interface (Logical AUX)
A future release of the SCIP will include the asynchronous AUX (RS-232) interface at this port for
connection to an external modem.
