2.3 SSXC Card

The single shelf cross-connect card (SSXC) is the central element for ONS 15600 switching. The SSXC

card establishes connections and performs time division switching (TDS) at STS-1 and STS-Nc levels

between ONS 15600 traffic cards.

The SSXC card works with the TSC card to maintain connections and set up cross-connects within the

ONS 15600. You establish cross-connect and provisioning information using CTC or TL1. The TSC card

stores the proper internal cross-connect information and relays the setup information to the SSXC card.

2.3.1 SSXC Switch Matrix

The switch matrix on each SSXC card consists of 6,144 STS-1 ports, with a maximum of 6,144 STS-1

cross-connections. When creating bidirectional STS-1 cross-connects, each bidirectional cross-connect

uses two STS-1 ports, with the result that the SSXC card supports 3,072 bidirectional STS-1

cross-connects. Any STS-1 on any port can be connected to any other port, meaning that the STS

cross-connections are non blocking. Non-blocking connections allow network operators to connect any

STS1, STS3, STS12, STS24, STS48, or STS192 payload that is received on an OC-48 or OC-192

interface (or any STS6 or STS9 payload that is received on an ASAP interface) to any other interface

capable of supporting the bandwidth.

The SSXC card has 128 input ports and 128 output ports capable of STS-48. An STS-1 on any of the

input ports can be mapped to an STS-1 output port, thus providing full STS-1 time slot assignments

(TSAs).

2.3.2 SSXC Slots and Connectors

Install an SSXC card in Slot 6 and a second SSXC card in Slot 8 for redundancy. (Slots 7 and 9 are also

occupied by the SSXC faceplate.) The SSXC card has no external interfaces. All SSXC card interfaces

are provided on the ONS 15600 backplane.

Cisco ONS 15600 Reference Manual, R5.0

2-6

describes the functions of the push-button switches on the TSC card faceplate.

TSC Card Push-Button Switches

Function

Extinguishes external audible (environmental) alarms. When this button

is activated, the amber-colored ACO LED turns on.

Verifies that all the LEDs in the shelf are functioning properly. When

this button is activated, all of the front-panel LEDs in the shelf turn on

temporarily to verify operation.

Activates a soft reset of all of the main processor memory on the card.

The RESET button is recessed to prevent accidental activation.
