TUNSTALL NETWORK CABLE
If using an existing 5 pair Tunstall Telecom cable always ensure none of the original equipment is left connected before
terminating the Advent xt system. Use the following colour code;
Other cable networks from previous systems can be used provided there are a minimum of 4 x 0.5mm twisted pairs
maintained throughout the site. Check the overall cable resistance from one end to another, check there is no resistance
between cores and check the cables are voltage free.
NETWORK CABLE LIMITATIONS
The maximum network cable length is 1200 metres - beyond this it is likely you will experience problems relating to
voltage drop, low audio levels and corrupt data.
Voltage drop can be overcome by increasing cable conductor size and adding additional PSU’s.
Low audio levels can only be overcome by increasing cable conductor size.
Corrupt data can be caused by cable length and/or too many devices on the network.
A Network Data Repeater (P/No. ZXT340) is available for extreme cases.
