63xE1(75ohm) Service Processing Board
Working with 2*D75S to transmit/receive and process 63xE1 signals
Supports E13 function, which is used to converge E1 services into E3 services.
Supports the CRC function.
Can replace the SSN1PQ1A.
Processes E1 signals, processes overhead bytes, reports alarms and performance events.
Provides maintenance features, and supports the TPS protection.
Supports the processing of the path overheads at the VC-12 level, such as the J2 byte.
Supports inloops and outloops at electrical interfaces.
Supports warm resets and cold resets. The warm reset does not affect services.
Supports the query of the manufacturing information of the board.
Supports the in-service loading of the FPGA.
Supports the upgrade of the board software without affecting services.
Supports the PRBS test in the tributary direction and in the cross-connect direction in the normal mode.
Not support the PRBS test in the MUX mode or Server mode.
Supports the TPS protection when working with the interface board.
SSN2PQ1A is a 63xE1 processing service processing board, can be used on Huawei OSN 1500B, OSN 2500, OSN 3500, OSN 7500. SSN2PQ1A part number is 03030KQL, model name is SSN2PQ1A01. SSN2PQ1A does't have interface on board front panel, it must work with 2 pieces of D75S 75ohm E1 interface board.
|The front panel of the SSN2PQ1A has indicators.|
OSN 1500B: The SSN2PQ1A can be installed in slots 11–13.
OSN 2500: The SSN2PQ1A can be installed in any of slots 5–7, 12 and 13.
OSN 3500: The SSN2PQ1A can be installed in any of slots 1–5 and 13–16.
OSN 7500: The SSN2PQ1A can be installed in any of slots 1–3, 17 and 18.
|The number code that follows the board name in the bar code is the feature code of the board. The feature code of the PQ1 indicates the type of interface impedance.|
|Board||Feature Code||Type of Interface Impedance|
|Optical Interface Parameter|
|The D75S, D12S, or D12B provides electrical interfaces for the PQ1. For the parameters specified for the electrical interfaces, see Technical Specifications of the D75S, Technical Specifications of the D12S and Technical Specifications of the D12B.|
|Dimensions (mm)||25.4 (W) x 235.2 (D) x 261.4 (H)|
Q: What’s the difference between different functional versions?
A: The PQ1 is available in N1 and N2 version, N1PQ1 is discontinued. Differences are as below:
|E13 function||Not supported||Supported|
|CRC function||Not supported||Supported|
Q: What's the difference between D75S and D12S?
A: D75S and D12S are E1 interface boards for PQ1, D75S is 75ohm, D12S is 120ohm.
Q: Can I use 120ohm cable connect on D75S?
A: No, you can’t, if you use 120ohm cable, please choose D12S interface board. To avoid incompatibility, please tell Thunder-link.com sales team your resistance.
Q: Does D75S /D12S come together with PQ1 board?
A: Yes, D75S / D12S price is inclusive in PQ1 board.
Q: Does E1 cable come together with PQ1 board?
A: No, you need purchase separately. To avoid incompatibility, please tell us your resistance
Q: How many E1 cable do I need?
A: PQ1 E1 cable is 8*E1 per PCS, you need 8PCS per each PQ1 board; length is 3m, 5m, 10m as per your needs. But in normally condition, 5 meter per each is enough.
Q: How could I do, if I have PQ1+D75S, but my DDF is 120ohm?
A: You may choose a 75ohm/120ohm converter, it looks like a DDF panel, can fix on your DDF rack to convert 75ohm to 120ohm.
Q: Can I return/exchange board if not compatible with my system?
A: Yes, please tell our sales team your system and main control board version, before your purchase.
Q: The board is new or refurbished?
A: Yes, it is original new, not been used.
Q: What is the lead time for SSN2PQ1A board?
A: In normal condition is 5 days, better to confirm with our sales team before your purchase.
