Configuring ESCON Signal Aggregation
This chapter describes how to configure ESCON signal aggregation on 10-port ESCON multiplexing
line cards and 10-Gbps ITU trunk cards on the Cisco ONS 15530. This chapter includes the following
sections:
• About ESCON Signal Aggregation Support
• Configuring ESCON Multiplexing Line Card Interfaces
• Configuring 10-Gbps ITU Trunk Card Interfaces
• Configuring 10-GE Uplink Card Interfaces
• About Cross Connections
• About Alarm Thresholds

About ESCON Signal Aggregation Support
The ESCON multiplexing line card aggregates up to 10 ESCON data streams into a single 2.5-Gbps
signal, which is transmitted through the switch fabric to a 10-Gbps ITU trunk card or a 10-GE uplink
card. The 10-Gbps ITU trunk card converts up to four aggregated signals to one ITU wavelength and
sends it to an OADM module. The 10-GE uplink card converts up to four aggregated signals into a 10-GE
1310-nm signal and sends it to a 10-GE client card on either a Cisco ONS 15540 ESP or Cisco ONS
15540 ESPx.
Figure 4-1 shows the path of an ESCON signal through the Cisco ONS 15530.
