STM-1/STS-3 Dual Bus Ethernet Mapper of 4 Port with 63v
EOSM155 (GC68505B-PI)
|
|
The EOSM155 is designed for SONET/SDH add/drop multiplexer, multi-service access platform for unidirectional single/dual ring applications.
Up to 4 Ports of Ethernet payload can be mapped/demapped into/from SONET/SDH Virtual Concatenation Group via the 4 RMII ports. SONET/SDH Low Order and/or High Order VC Virtual Concatenation SPE are supported, Virtual Concatenation SPE formats support up to VC3-3v/ VC12-63v/ VC11-64v. External RAM interface is also provided to compensate transmission delays for different VCG members. |

|
| 1. |
Support up to 4 RMII Port, each RMII port can be separately configure to support 10/100M operation |
| 2. |
Support Ethernet Frame (RMII) Encapsulation/De-capsulation Protocol of:
| - |
ITU-T G.7401, Generic Framing Procedure (GFP) |
| - |
ITU-T X.86 Link Access Procedure SDH (LAPS) |
|
| 3. |
Virtual Concatenation Group can support up to VC3-3v or VC12-63v or VC11-64v |
| 4. |
External RAM Interface is provided to compensate Transmission Delay of different Virtual Concatenation Group Members. Up to ±255ms Differential Transmission Delay can be compensated using 128Mb SDRAM |
| 5. |
Low latency (e.g. less than 200us for the Ethernet frame of 64 bytes by VC12-5v) supports excellent performance for Ethernet switching applications |
