10.1Any Service Any Port Card Application

The Any Service Any Port (ASAP) Carrier Card plugs into any of the eight available I/O slots for the ONS 15600. Each ASAP carrier card has four slots available for up to and including four ASAP Pluggable Input/output Modules (PIMs). There are four slots available on the PIM for Pluggable Port Modules (PPM), which are Small Form-factor Pluggable (SFP) optics. Four PPMs per ASAP PIM are allowed, which means that there can be as many as 16 PPM optical network interfaces for each ASAP carrier card. Each PPM can support any of the following single-rate SFP optics:

•OC-3 LR-2

•OC-12 LR-2

•OC-48 LR-2

Each of the PPM ports also supports the following multirate SFP optics:

•OC-3-SR-1

•OC-12-SR-1

•OC-48 IR-1

•GE LX
