About this Document
This document describes in detail the initial feature set for the SpectraComm IP
Router Card. Briefly mentioned are several additional features (DDS support and
modem facilities) which are planned for a future release. 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.
SpectraComm IP Overview
The SpectraComm IP (SC-IP) router card extends the carrier's internal network to
remote locations where separate IP networks are required. SC-IP also functions as
a LAN-extension device which extends the carrier's internal network to remote
locations where a single 'flat' IP network is required.
SpectraComm IP as Static IP Router
As a static IP router, SC-IP forwards IP data between serial WAN ports and an
Ethernet (LAN) switch. SC-IP's eight-port terminal server can connect to craft
ports of co-located devices to provide out-of-band access.
Typically, the SC-IP provides connectivity via a T1 port. The link layer WAN
protocols supported are Frame Relay and the Point-to-Point Protocol (PPP).

SC-IP as LAN-extension Device
When placed in LAN-extension mode, the SpectraComm IP extends the Carrier's
local area network(s). Deployed in pairs, the SC-IPs 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 SC-IP configured for LAN-X at each end of
the WAN.

Typical Installations
The SC-IP is a rack-mount card that installs in a SC 5000 shelf (16 slots) or in a SC
2000 shelf (2 slots). For stand-alone, non-NEBS applications, the SC-IP card can
be installed in the SC 1001 or SC 1002 standalone enclosure.
