Main Features

| 1+1 line protection
| Monitors optical connections via LOS Loss of Signal
| Switching time <25 ms
| Latched switch for fiber security, even in case of power failures
| Protocol and data transparent (2 Mbps –40 Gbps)
| Fits CATS Converged Access & Transport Platform

COST switch card, integrating intelligent fiber-optic switch, protects optical fiber connections in case of failures. Immediately after an error is detected, it automatically switches the link to an alternative line within a reaction time of max. 25 ms, less than Sonet/SDH requirement of 50 ms.

Protocol and data rate transparent, COST switch card provides 1+1 protection to any point-to-point fiber optic transmission line.

Management Features

| SNMPv.2 agent and CLI
| Secure configuration via SSHv2 (Secure Shell) terminal
| GUI based network management via CATS system controller

Application

COST optical switch card can be used stand-alone within CATS 1000 platform. It is managed by CACC system controller, with which the user can monitor and configure the switch.

Controllable parameters include automatic switch-over Enable or Disable, and LOS detection threshold. When automatic switch is disabled, user can switch over manually.

COST can also be used within larger CATS platform such as CATS 3000. In combination with CATS CLCT, CLXT, CLFT and COAT cards, it can form a powerful protected WDM transmission link in point-to-point, linear chain, or ring network configuration.
