Use this information to help identify the 12X cables and
system power control network (SPCN) cables for the expansion unit.
The system uses 12X SDR or 12X DDR cables to send and receive
customer data and auxiliary control information to and from the expansion
unit, and to download expansion unit firmware. The SPCN is used to
control power to the expansion units and is used as a backup to the
12X cables for auxiliary control and firmware download.
12X SDR cables
Observe the following guidelines
when you are determining whether to use a 12X SDR cable:
- A 12X SDR cable can be used only with 5796, 5797, 5798, and 7314-G30
expansion units.
- A 12X SDR cable cannot be used in place of a 12X DDR cable.

12X DDR cables
Observe the following guidelines
when you are determining whether to use a 12X DDR cable:
- Any 12X DDR cable can be used in any 12X application, as long
as the specified length restrictions are observed.
- A 12X DDR cable can be used instead of a 12X SDR cable, as long
as the specified length restrictions are observed.
