CTX2500 Card Description

The CTX2500 card, for use with the ONS 15310-MA, 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, SONET DCC
termination, system fault detection, and cross-connect maintenance and management for the
ONS 15310-MA. The card also provides the circuitry for the OC-3/OC-12/OC-48 interfaces, and
ensures that the system maintains timing with SMC stability.
Caution If the system loses poweror the CTX2500 card is reset, you must reset the ONS 15310-MA clock unless
the node has been previously provisioned to use Simple Network Time Protocol (SNTP) to update the
clock over the LAN.
