ESCON Aggregation Cards
The ESCON aggregation card is a 10-port card for ESCON (Enterprise Systems
Connection) traffic. The ESCON card converts the 10 client signals from optical
to electrical and then aggregates them into a single 2.5-Gbps signal. This
aggregated signal is sent through the backplane and the active switch fabric to
either a 10G ITU trunk card or a 10-Gbps uplink card. The cross connection
between the two cards is configured using the CLI (command-line interface). The
ESCON aggregation card has a redundant backplane connection.
The ESCON aggregation card uses multi-mode 62.5/125 um optical cable with
SFPs (small form factor pluggables) and MT-RJ connectors for the client signals.
(See Figure 1-21.)
Note The SFPs (part number 15500-XVRA-01A2 ONS 15530 ESCON-1310nm
MM-MTRJ) must be purchased separately.
Note A patch cable to adapt MT-RJ connectors to standard ESCON connectors directly
or intermediately to SC-type connectors may be required.
This signal is sent through the switch fabric to a 10G ITU trunk card or a 10-Gbps
uplink card. The 10Gbps ITU trunk card converts the aggregated signal to an
ITU-compliant wavelength, or channel. The 10-Gbps uplink card converts the
aggregated signal to transmit to another shelf.
