Chapter 3 Card Reference Electrical Card Protection 3.2.1 1:0 Protection The term 1:0 protection is sometimes used for an unprotected configuration. 3.2.2 1:1 Protection In 1:1 protection, a working card is paired with a protect card of the same type. If the working card fails, the traffic from the working card switches to the protect card. When the failure on the working card is resolved, traffic automatically reverts to the working card.
PAGE 126
Chapter 3 Card Reference Electrical Card Protection The physical E-1 or DS-3 ports on the ONS 15454 SDH FMEC cards use the working card until the working card fails. When the node detects this failure, the protection card takes over the physical E-1 or DS-3 electrical interfaces through the relays and signal bridging on the backplane. Figure 3-2 shows the ONS 15454 SDH in a 1:N protection configuration. Each side of the shelf assembly has only one card protecting all of the cards on that side.
PAGE 127
Chapter 3 Card Reference Optical Card Protection The ONS 15454 SDH supports 1:N equipment protection for all add-drop multiplexer configurations (ring, linear, and terminal), as specified by ITU-T G.841. The ONS 15454 SDH automatically detects and identifies a 1:N protection card when the card is installed in Slot 3 or Slot 15. However, the slot containing the 1:N card in a protection group must be manually provisioned as a protect slot because by default all cards are working cards. 3.2.
PAGE 128
Chapter 3 Card Reference Unprotected Cards (1:0 Protection) 3.5 Unprotected Cards (1:0 Protection) Unprotected cards are not included in a protection scheme; therefore, a card failure or a signal error results in lost data. An unprotected configuration is sometimes called 1:0 protection. Because no bandwidth is reserved for protection, unprotected schemes maximize the available ONS 15454 SDH bandwidth. Figure 3-3 shows the ONS 15454 SDH in an unprotected configuration. All cards are in a working state.

Glossary Priority queuing Routing feature that divides data packets into two queues: one low-priority and one high-priority. Protect card A card in a protection pair or scheme that is provisioned as a protect card to the working card. If the working card fails, the protect card becomes active. See also working card. Provisioning user A security level that allows the user to access only provisioning and maintenance options in CTC. See also Superuser, Maintenance user, and Retrieve user.
PAGE 248
Glossary Revertive switching A process that sends electrical interfaces (traffic) back to the original working card after the card comes back online. Rising threshold The number of occurrences (collisions) that must be exceeded to trigger an event. RJ-45 Registered Jack #45 (8-pin). RMA Return Materials Authorization. RMON (Remote Network Monitoring). Allows network operators to monitor the health of the network with a Network Management System (NMS).

Glossary SES Severely Errored Seconds. SF Super Frame. SML Service Management Layer. SMF Single Mode Fiber. SNCP (Subnetwork Connection Protection Ring). Path-switched SDH rings that employ redundant, fiber-optic transmission facilities in a pair configuration. One fiber transmits in one direction and the backup fiber transmits in the other. If the primary ring fails, the backup takes over. SNMP (Simple Network Management Protocol).
PAGE 250
Glossary SSM (Synchronous Status Messaging). A SONET protocol that communicates information about the quality of the timing source using the S1 byte of the line overhead. STA (Spanning-Tree Algorithm). An algorithm used by the spanning tree protocol to create a spanning tree. See also Spanning tree and STP. Standby card A card that is not active or carrying traffic. A standby card can be a protect card or, after a protection switch, a working card can be a standby card.
