OC-3 Cell Interface Module (OC3MM / OC3SM) |
The OC-3 SONET Cell Bearing
Module is a compact subassembly that occupies one of the 15 slots available. The OC-3
SONET Cell Bearing Module terminates an OC-3 facility interface, recovers clock, accesses
the ATM cells within the SONET payload, and send these cells to the switching fabric. In
the transmit direction the process is reversed. ATM cells are taken off the switching
fabric and mapped into the SONET payload, which is then properly formatted and clocked out
on the OC-3 facility. The OC-3 SONET Cell Bearing Module is available with single mode
(long haul) fiber or multi- mode (short haul) fiber.
