Installation & Maintenance
INDeX 30
Whilst Avaya do not supply the MDF panel as part of the INDeX 30, we strongly
recommend that you provide 32 connection pair MDF for the system. This greatly
simplifies maintenance and upgrading.
The MDF cable supplied with an INDeX 30 is a 3m 32 twisted-pair cable (other
lengths can be ordered if required). The twisted-pairs are separated into 3 groups of
10 pairs by coloured wrappers plus two loose pairs. Refer to "MDF Cable
Connection" on page 17 for details.
General Connection Requirements :
1. Connect the cable to the MDF socket.
2. Ensure that PSTN connections are wired onto separate connection strips from
any other equipment (e.g. Terminals). This is a BABT requirement.
3. Ensure that the cable and each wire connection is labelled with its type and
address (channel number, etc).
4. The diagram below is only indicative of the maximum cable distances (for BRI
connections, see "Basic Rate ISDN Cabling" on page 16).
