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.
