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 power or 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.

CTX2500 Card Description
The CTX2500 card provides 576 x 576 STS-1 level cross-connections and 2688 x 2688 VT1.5s.
The CTX2500 card can be installed in Slot 3 or 4. Protection switches between the active and standby
CTX 2500 are hitless (less than a 50-ms impact to any traffic).
The CTX2500 supports errorless side switches (switching from one CTX2500 on one side of the shelf
to the other CTX2500 on the other side of the shelf) when the switch is initiated through software or is
caused by a software upgrade.
There are two PPM (SFP) slots on the CTX2500 faceplate. Each slot can contain a one-port PPM.
Cisco-qualified SFPs can be single-rate (OC-3, OC-12, or OC-48) or multirate (OC-3/OC-12).
Single-rate PPMs are autoprovisioned when they are installed, but multirate PPMs must be provisioned.
This behavior can be controlled by NE defaults.

CTX2500 Card-Level Indicators
The CTX card has four card-level LEDs, described in Table 1.

CTX2500 Card Specifications
catastrophic software failure occurred on the card. As part of the boot
sequence, the FAIL LED turns on and flashes until the software deems the
card operational.
The ACT/STBY LED is green if the card is the active CTX2500 card. It is
amber if the card is the standby card.
The SYNC LED is green if the CTX2500 card detects both a primary and
secondary clock reference. It is amber if the card detects only a single clock
reference.
Two bicolor LEDs show the status per port (Ports 1 and 2). The port LED is green if the port is available
to carry traffic and is provisioned as in-service. The port LED is red if there is a signal failure or loss of
signal on the port.
