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.
