Card Slots and Types

Cisco ONS 15454 SDH Product Overview, R3.4

September 2002

The ONS 15454 SDH shelf assembly contains 17 card (module) slots in the lower

shelf, 12 Front Mount Electrical Connection (FMEC) slots in the upper shelf, a

fan tray, a front panel with a liquid crystal display (LCD), and alarm indicators.

All card and electrical connections are accessible from the front of the chassis.

The ONS 15454 SDH carries traditional time-division multiplexing (TDM) and

high-speed data traffic. A variety of card configurations offer incremental

bandwidth increases as needed and support E-1, E-3, DS-3i, STM-1, STM-4,

STM-16, STM-64, 10/100 Ethernet, and Gigabit Ethernet speeds.

PCs and workstations can connect to the ONS 15454 SDH using direct, network

(LAN and WAN), or data communications channel (DCC) connections. Cisco

TransportController(CTC), the ONS 15454SDH software interface, provides easy

card-, node-, and network-level provisioning and troubleshooting. The ONS

15454 SDH deploys a variety of network configurations, including point-to-point

1+1 linear multiplex-section protection systems, point-to-point 1+1 linear

add/drop multiplexers (ADMs), subnetwork connection protection rings

(SNCPs), two-fiber and four-fiber multiplex section-shared protection rings

(MS-SPRings), subtending rings, and extended SNCP mesh networks.

Card Slots and Types

The ONS 15454 SDH lower shelf assembly has 17 card slots numbered 1 to 17.

When you plug in a card, it automatically boots up and becomes ready for service.

The cards offer bandwidth in modular increments, making it efficient to deploy

the system in low-density applications and add bandwidth as needed. The ONS

15454 SDH lower shelf assembly houses four types of cards: common control,

electrical, optical, and Ethernet. The common control cards include the Timing

Communications and Control–International card (TCC-I) and the 10 Gigabit

Cross Connect card (XC10G). Slot number 9 is reserved for the Alarm Interface

Controller–International card (AIC-I).

The upper shelf assembly has 12 FMEC slots numbered 18 to 29. FMECs provide

serial ports, LAN ports, a modem connection for future use, electrical

connections, redundant power supplies, timing connections, and alarm

connections for the AIC-I card.

ONS 15454 SDH cards, when installed in a system, comply with IEC 60950, EN

60950, UL 60950, CSA C22.2 No. 60950, TS 001, and AS/NZS 3260 safety

standards.
