RE-01GP48-S15KLC
This is a one-port POS48 single-channel optical interface card,
providing one-channel standard OC-48c/STM-16c POS optical
interface.
In the receiving direction, this card extracts payload from 2.5
Gbps optical signals and provides PPP packets for the packet
processing card through the bus. In the transmitting direction,
this card receives PPP packets from the packet processing card
through the bus. This card maps the packets into SONET/SDH
virtual containers VC-4-16c, and then sends the packets through
the 2.5 Gbps optical interface.
Figure 15 shows the RE-01GP48-S15KLC card.
