Introduction and Specifications
SC-IP Router Applications
The primary application of the SC-IP is in router mode, providing low-cost, NEBS-compliant IP
connectivity to the carrier's internal network and between managed sites. NEBS-compliant SC-IP
can be located anywhere within a carrier's network; for example SC-IP 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.
Figure 1-1
shows a typical Network Operations Center managing its remote equipment via a
SC-IP at a remote site. With a SC-IP 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.
The SC-IP can be accessed from the NOC over the Carrier's data network using multiple WAN
interfaces, such as its integral T1 CSU/DSU. In a future release, a synchronous DTE interface to an
external 56/64K DSU (SC521A) is supported.
The SC-IP 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 SC-IP.
Note
The SC-IP's LAN-X and IP forwarding functions are mutually exclusive; that is, when the SC-IP is used in
router applications, it cannot employ its LAN-X mode of operation.
