Install Fiber Optic Cable Pass-Thru Kit (Multicarrier Cabinets)

Administering Fiber Optic Cables for R10r

When a fiber optic cable is properly labeled, it is easy to trace the desired circuit by looking at the labels on the cross-connect, the cable itself, and the individual fibers in the cable.

Fiber Link Administration Form

This form administers fiber links, each of which is identified by a fiber number.

Port networks (PNs) are connected via direct fiber link connections or through a center stage switch (CSS) to provide the interconnection of port networks required for voice/data information transfer. The CSS is composed of "switch nodes" that can be interconnected in one or two levels to provide Port Network Connectivity (PNC). The CSS provides circuit-switched connectivity for voice and data communications as well as packet-switched connectivity. Fiber link administration permits an administration of translation data associated with a switch connection (such as optical fiber, metallic cable, or DS1CONV circuit packs and DS1 facility links between two endpoints). The two fiber endpoints can be:

• An expansion interface (EI) circuit pack


• A switch node interface (SNI) circuit pack

Administration commands

Use the following commands to administer the Fiber Link Administration form.

PN reliability configurations

PNCs have three different reliability configurations (one for each system reliability configuration) as follows:

Simplex PNC

For Simplex PNC, PNC Duplication is disabled with a license file and Duplication is disabled on the Duplication-Related System-Parameters form.
