The customer wonders whether the Ethernet boards on the OptiX OSN 3500 support the following features and relevant protocol standards:
GFP (G.7041/Y.1303) yes/no
X.86 (LAPS) yes/no
MLPPP (BCP) yes/no
GFPoPDH (G.8040) yes/no
VCAT (G.7043) yes/no
LCAS (G.7042) yes/no
? HDLC: On the OptiX OSN equipment, the Ethernet boards for transparent transport, such as the N1EGT2, N1EFT8, and N1EFT8A, and the N1EMS4 and N1EGS4/N3EGS4 support HDLC.
? GFP (G.7041/Y.1303): On the OptiX OSN equipment, all the Ethernet boards support GFP encapsulation. The GFP encapsulation is the default encapsulation format. G.7041 and Y.1303 indicate two numbers that ITU-T specifies for GFP.
? X.86 (LAPS): On the OptiX OSN equipment, only the N1EMS4 and N1EGS4/N3EGS4 support X.86 (LAPS).
? MLPPP (BCP): On the OptiX OSN equipment, no Ethernet board supports MLPPP (BCP).
? GFPoPDH (G.8040): GFPoPDH (G.8040) is associated with PDH. On the OptiX OSN equipment, no Ethernet board supports GFPoPDH (G.8040).
? VCAT (G.7043): On the OptiX OSN equipment, all the Ethernet boards support VCAT. G.7043 specifies the VCAT of the PDH signals that the OptiX OSN equipment does not support. Therefore, the OptiX OSN equipment supports VCAT, but does not support G.7043.
? LCAS (G.7042): On the OptiX OSN equipment, all the Ethernet boards support LCAS (G.7042), except the N1EGS2.
The preceding features are specific to OptiX OSN equipment V100R007 and earlier. OptiX OSN equipment V100R009 and later may use new boards that support new features.
During the exchange with the customer, the engineers find that the customer is unfamiliar with the relevant background knowledge and concepts.
The OptiX OSN equipment functions as a multi-service transport platform. Certain customers wonder how to transport Ethernet services by using the PDH technology. Therefore, the engineers need to learn the PDH knowledge.
