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 units in a carrier’s network. Multiple pairs 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.
