HIM-RS2P
The HIM-RS2P is a 2.5 Gbps OC-48/STM-16 Resilient Packet Ring (RPR) interface module. It
provides two SFP RPR ports and two SFP Mate ports. Each RPR port is provided with six status
LEDs, which show the running status and fault detection status of RPR and optical interface at the
physical layer.
The HIM-RS2P supports:
•
Two frame formats: SDH STM-16 and SONET OC-48C.
•
Line clock mode and internal clock mode.
•
Loopback tests such as data loopback test, external SONET/SDH loopback test, and external
link loopback test.
