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.

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.
