Connecting and Handling Fiber Optic Cables

Administering Fiber Optic Cables for R8r


Note: You adminster Fiber Optic Cables only on a DEFINITY ECS Release R8r in a Multi-Carrier Cabinet.

When a fiber optic cable has been 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.


Note: Fiber link administration only applies to R5r and later configurations.

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:


Note: Only one administrative terminal can administer fiber links at a time; others can display fiber link information.

Brackets [ ] indicate the qualifier is optional. Single quotes (` `) indicate the text inside the quote must be entered exactly as shown or an abbreviated form of the word may be entered.

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

System Configuration
PNC

Standard Reliability

Simplex Fibers

High Reliability

Simplex Fibers to Expansion Port Networks and

Duplicated Fibers between Processor Port Networks (PPN) and Switch Nodes

Critical Reliability

Duplicated Fibers

Simplex PNC

For Simplex PNC, PNC Duplication is disabled on the System-Parameters Customer-Options form and Operation of Duplication is disabled on the Duplication-Related System-Parameters form.
