Chapter 1: Introduction and
Specifications
SpectraComm IP Overview
The SpectraComm IP T1 (SCIP) functions as a router, extending the carrier’s
internal IP network to remote locations where separate IP networks are required.
SCIP also function as a LAN-extension devices which extend a carrier’s internal
IP network to remote locations where a single ‘flat’ IP network is required.
SCIP is also available with an integral modem which provides secure modem
access to remote devices at data rates up to 33.6 Kbps
SpectraComm IP as Static IP Router
As a static IP router, SCIP forwards IP data between serial WAN ports and an
Ethernet(LAN) switch.SCIP’s eight-portterminalservercanconnect tocraftports
of co-located devices to provide out-of-band access.
Typically, the SCIP provides connectivity via a T1 port. The link layer WAN
protocolssupportedareFrameRelayandthePoint-to-PointProtocol(PPP).Figure
1-2 shows SCIP deployed in a Frame Relay, T1 network.
SCIP as LAN-extension Device
When placed in LAN-extension mode, the SpectraComm IP extends the Carrier’s
local area network(s). The eight-port terminal server can connect to craft ports of
co-located devices to provide out-of-band access. Deployed in pairs, the SCIPs are
connected to their separate LANs via the ethernet interface, and are connected to
each other via the WAN. GDC’s proprietary LAN-extension (LAN-X) is
comprised of a link layer WAN protocol (LAN-X) which requires a SCIP
configured for LAN-X at each end of the WAN. Figure 1-3 shows SCIP extending
local and remote LANs.
Typical Installations
The SCIP is a rack-mount card that installs in a SC5000 shelf (16 slots) or in a
SC2000 shelf (2 slots).For stand-alone, non-NEBS applications,the SCIP card can
be installed in various models of the SpectraComm standalone enclosure.
Note The SpectraComm IP T1 router card is part of the SpectraComm IP family of products. In this document,
SCIP refers to the T1 product. Other products, such as the SCIP-E1, SCIP-DSL and SCIP-DSL.bis are
described in their respective manuals.

Issue 13 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 (Figure 2-1).
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 equipmenton 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.

Management
In RouterMode, remote SCIPscan bemanaged from theCentral Office via Remote Default Routes.
In LAN-X mode, local and remote SCIP devices can be managed and pinged from either site.
Management protocols available in SCIP are described briefly below.
Smart CLI
The SCIP 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.
Enhanced Telnet/SSH Management
SCIP provides enhanced Telnet or SSH “cut-thru” to up to eight LAN-attached devices via rear
panel terminal server connector. Using the SCIP management IP address, remote devices are
accessed by menu and a TCP port number (2001 - 2008 for Telnet, 3001 - 3008 for SSH) rather than
separate IP addresses for each device.
Remote Dial-Up Management
When the SCIP is equipped with an integral modem, it can be managed via a password-protected
dialup connection from the Central Office.
TFP or TFTP Services
SCIP supports File Transfer Protocol (TFP) and Trivial File Transfer Protocol (TFTP) servers for
the downloading of GDC firmware (Flash) upgrades. These services can be enabled and disabled.
Web Management
The SCIP supports direct web management via HTTP for internet-ready network monitoring. An
embedded web server agent allows Read or Read-Writeaccess to SCIP using popular browsers. To
enhance security, SCIP supports web time-outs and password-protected access over the web
interface. HTTP services can also be disabled to block web access to SCIP devices.
SNMP Management
An embedded SNMP agent allows discovery, retrieval of statistics, alarm traps and Read access to
SCIP using any standard SNMP controller. SNMP access can be disabled to avoid hacks during
intervals of heightened security.
Note SNMP support will not require a SpectraComm Manager (SCM) card co-located in the shelf.
TEAM Management (Future Release)
The SCIP supports auto-discovery and polling by GDC’s TEAM software. TEAM uses HPOV APIs
(Application Programmer Interfaces) to integrate with HP OpenView Windows and other network
management applications. In a future release, the SCIP will be able to launch a direct Telnet or web-
based CLI session from the map window. For more information, contact your GDC representative.
Note TEAM support requires an SCM card at version 5.80 or greater and co-located in the shelf with the SCIP.
For more information, refer to the GDC TEAM Core documentation and Release Notes.

Diagnostic Tests
SCIP supports T1 diagnostics which can assist equipment installers in isolating T1 network
problems. Installers initiate diagnostic tests using CLI commands via a terminal connection to the
SCIP front panel Craft port or through a Telnet connection. Diagnostics consist of self-tests,
loopback tests and checks as follows:
• T1 Network Line Loopback Test
• T1 Self Test with Loopback
• T1 Self Test
• T1 Payload Loopback Test
Diagnostic Tools
• SCIP supports the standard traceroute application which is used to determine the path an IP
packet follows through the network. It is a useful tool for diagnosing IP connectivity problems.
Traceroute is invoked by the trace-rte command.
• System messages (SYS MSG) are useful in debugging TACACS+ failures. The last 100 system
messages can be viewed with the show log sysmsg command.
• When the SCIP is configured for LAN-X mode, the diags lanx command can be used to
send different sized test packets to the remote SCIP which loops them back to the sender. This
diagnostic check is independent of IP and does not use ICMP (ping).
• Network Statistics displays information about the current TCP socket connections, such as the
local or remote IP address, send and recieve window sizes, state, etc. To show the Network
Statistics, type: show netstat.
Alarms
SCIP supports standard T1 network alarm reporting which informs users about catastrophic or
impaired line conditions. Alarms can be enabled and configured to display at user-specified
intervals. Alarms disabled by the user will be masked and the front panel ALM led will not light
when the particular alarm event occurs. Supported T1 alarms are as follows:
• Out Of Frame (OOF) alarm
• Loss of Signal (LOS) alarm
• Alarm Indication Signal (AIS)
• Bipolar Violation (BPV) alarm
• Cyclic Redundancy Check (CRC) error alarm
• Received Yellow (RYEL) alarm event
• Low Average Density (LAD) alarm
SNMP Traps
SCIP can generate SNMP traps on various events, and employs a more reliable method for sending
them to as many as four trap hosts. By storing traps and verifying connectivity before sending, trap
delivery is greatly improved in the event of temporary network outages. Supported traps are:
• Cold Start trap
• LinkUp/Down traps for ethernet0, serial0, serial1, and modem0 (if so equipped)
• Up/Down traps for etherswitch port1 and etherswitch port2
• Contact Sense trap for Start/Stop; Contact Sense trap for Active/Clear
• MACL Violation trap; Authentication Failure trap

SCIP Router Applications
The primary application of the SCIP is in router mode, providing low-cost, NEBS-compliant IP
connectivity to the carrier’s internal network and between managed sites. SCIP can be located
anywhere within a carrier’s network; for example SCIP can be located within the Central Office
environment as part of the inside plant, or can be deployed in a remote office or CEV-Hut
environment as part of the outside plant.
The SCIP can be accessed from the NOC over the Carrier’s data network using multiple WAN
interfaces, such as its integral T1 CSU/DSU. A synchronous DTE interface to an external CSU/
DSU is also provided.
The SCIP in router mode exclusively uses static routes to ensure a greater degree of security and
reduce IP traffic in the carrier’s network. This requires the addition of static routes at the NOC and
the SCIP.
Figure 1-2 shows a typical Network Operations Center managing its remote equipment via a
SCIP at a remote site. With a SCIP deployed in all remote offices, virtually all remote devices can
be connected back to the NOC through remote device ethernet (LAN) ports or their craft ports.
Note The SCIP’s LAN-X and IP forwarding functions are mutually exclusive; that is, when the SCIP is used in
router applications, it cannot employ its LAN-X mode of operation.

SCIP LAN-X Applications
A Network Operations Center (NOC) can extend its LANs via one or more pairs of SCIPs. The
SCIPs would be configured for LAN-X mode and connected back-to-back over the WAN. This
configuration provides a NEBS-compliant extension of a Carrier’s LAN so that any remote device
may be accessed from the NOC via the SCIP.
For example, back-to-back SCIPs can extend the LAN within a building (i.e., between floors) or,
more typically, across a WAN connection. Figure 1-3 shows a typical deployment of one pair of
SCIP unitsin a carrier’s network. Multiplepairs of SCIP units can be deployed to fan out the NOC’s
reach to additional remote sites.
Note The SCIP’s LAN-X and IP forwarding functions are mutually exclusive; that is, when the SCIP is placed in
LAN-extension mode, the IP routing functions are not available.
