2.3 SSXC Card

For hardware specifications, see the
Note
The SSXC is the central element for ONS 15600 SDH switching. The SSXC card establishes
connections and performs time division switching (TDS) at VC3 and VC4-Nc levels between
ONS 15600 SDH traffic cards.
The SSXC card works with the TSC card to maintain connections and set up cross-connects within the
ONS 15600 SDH. 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 VC3 ports, with a maximum of
6,144 bidirectional VC3 cross-connections. When creating bidirectional VC3 cross-connects, each
bidirectional cross-connect uses two VC3 ports, with the result that the SSXC card supports 3,072
bidirectional VC3 cross-connects. Any VC3 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 VC3, VC4, VC4-4c, VC4-8c, VC4-16c, or VC4-64c payload that is received on an STM-16
or STM-64 interface (or additionally any VC4-2c and/or VC4-3c 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 VC4-16c. A VC3 on any of the input
ports can be mapped to an VC3 output port, thus providing full VC3 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.
Note The RESET button is recessed to prevent accidental activation.
