2.2 15310E-CTX-K9 Card

The 15310E-CTX-K9 card, for use with the ONS 15310-MA SDH, is a fully nonblocking cross-connect

card that operates in either a simplex or duplex (redundant) configuration. It performs system

initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution,

SDH DCC termination, system fault detection, and cross-connect maintenance and management for the

ONS 15310-MA SDH. The card also provides the circuitry for the STM1/STM4/STM16 interfaces, and

ensures that the system maintains timing with SETS stability.

Caution If the system loses power or the 15310E-CTX-K9 card is reset, you must reset the ONS 15310-MA SDH

clock unless the node has been previously provisioned to use Simple Network Time Protocol (SNTP) to

update the clock over the LAN.

Figure 2-2 shows the 15310E-CTX-K9 card faceplate and block diagram.
