Note
The 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 bidirectional STS-1 ports, with a maximum of
6,144 bidirectional 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 nonblocking. Nonblocking connections allow network operators to
connect any STS-1, STS-3, STS-12, STS-24, STS-48, or STS-192 payload that is received on an OC-48
or OC-192 interface (or additionally any STS-6 and/or STS-9 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).

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.
