The IP-20F includes two ch-STM-1/OC-3 ports, which can be used as a 1+1 STM-1/OC-3
protection configuration. The STM-1/OC-3 port provides an interface for up to 63 E1 or
84 DS1 lines inside a standard channelized STM-1 or OC-3 signal. Each E1/DS1 line is
transported by a VC-12 container, which behaves like a regular line interface.
Note:
STM-1/OC-3 requires the addition of an optional rear-mounted
STM-1/OC-3 module, which is planned for future release.
