Siemens S30810-Q2096-X200 DIUS2
The DIUS2 (Digital Interface Unit ISDN) implements two S2 primary rate access (PRA) interfaces in the Hicom 300 system according to CCITT:
- Receive path for PRAs 0 and 1. Transmission rate: 2048 kbit/s, coding: HDB3
- Send path for PRAs 0 and 1. Transmission rate: 2048 kbit/s, coding: HDB3.
- Signalling comprises 30 B-channels, 1 D-channel and 1 synchronization channel per path
The digital DIUS2 board is used for connections to public ISDN networks and for networking Hicom systems.
The DIUS2 (S2 interface for 4-wire line) is installed in the LTU in a peripheral board slot with an uneven number, since the slot immediately adjacent to it is also used.
S2M = Exchange trunk connection Da2M = digital tie-line (public network) S2 = digital tie-line (private networks) for connection to HOST, SERVER, GATEWAY.
For failure protection reasons, the two links on the same board should not be routed to the same partner. The range is 6 dB (approx. 240 m).
The transmission bandwidth is 2 x 2048 kbit/s (2 HWYs). Each HWY consists of 30 user channels (B-channels), one signalling channel (D-channel) and one synchronization channel with 64 kbit/s each.
Integrity counters maintain statistics for layer 2 protocols on the S0/S2 interface. The statistical data can be interrogated via AMO BSSU.
The DIUS2 processes the signalling data (s-data) of the D-channel. The DIUS2 provides a reference clock for the clock generator; this clock is obtained from one of the two link signals. For this purpose, the reference clock table must be assigned according to the network topology (AMO REFTA).
