Your question about Siemens S30810-Q2196-X DIUN2

The Digital Interface Unit ISDN module (DIUN2) for HiPath 4000, implements two Primary Access (PMA)-interfaces S2, in accordance with CCITT : Incoming block signals of the lines 0 and 1. Transfer Rate: 2048 kbit/s, Encoding: HDB3 outgoing block signals of the signaling channel and 1 signaling channel per line.

These boards are designed to connect to public and private E1 networks and subscribers. Also, the boards fulfill the Nx64Kbit feature. The DIU-N2 has two/four line-interfaces (ports). If the LTUW shelf use the LTUCX board, then the DIU-N2 can choose between the old or the new PCM highways. If the LTUW shelf use the LTUCE board, then the DIU-N2 is connected to the old PCM highways.

Following features are available: Number of ports:

• DIU-N2 2ports

Type of connection:

• Fiber optical interface 
•  75 Ohm copper interface
• 120 Ohm copper interface
• Receive clock recovery for network mode on all ports

At the DIU-N2 (DIU-C) an optical line access is available at FRONT or BACK. The copper line access is possible at FRONT only. To link the optical fibers to the front panel, three new adapter modules (AMOM) are used.
