The SSR2PD1A is a PDH processing board which adds tributary signals to line signals and drops tributary signals to line signals. This board has another name, SSR2PD1A01, so that you can use different names to search at Thunder-link.com which sells various transmission boards including SSR2PD1A. Thus you will enjoy your shopping tour at that site.
The SSR2PD1A can be used on the OptiX OSN1500B equipment to transmit/receive process 32xE1 signals. The series of PD1 is available in two functional versions, namely, R1 and R2. The difference between the two versions is with regard to their function: R2PD1supports the PRBS test in the tributary direction and in the cross-connect direction in the normal mode or MUX mode and does not support the PRBS test in the Server mode; The R1PD1 supports the PRBS test in the tributary direction and in the cross-connect direction and does not support the CRC function, but the R2PD1 supports the CRC function. The R1PD1A can be replaced with the R2PD1A when the required conditions are met. So you should pay attention to the difference.
In the case of SSR2PD1A of OptiX OSN 1500B equipment, it must be used with the D75S, D12S, or D12B. In the OptiX OSN 1500B sub-rack, the slots valid for the SSR2PD1A01 vary with the cross-connect capacity of the sub-rack. When the cross-connect capacity is 20 Gbit/s, the PD1 can be installed in divided slots 1–3, 6–8, and 11–13.The valid slots of SSR2PD1A are slot 1, 2 3, 6, 11, 12, 13, 15, 16, 17.
The feature code of the SSR2PD1A indicates the type of interface impedance. The relationship between the feature code of the PD1 and the type of interface impedance is: the feature code of SSR2PD1A and SSR1PD1 is A01; Type of Interface Impedance is 75-ohm.
Huawei transmission boards own a good word-of-mouth and a large scale market in the overseas. With the rapid development of the society and economy, the prospect of this field will be better and better. What’s more, SSR2PD1A will play a duteous board, service the people and society.
