3.12 Interconnect cables
3.12.1 V.24 Adapter Cable
A V.24 adapter cable (S30122-x5468-x5-*) is used for connecting HiPath 1100 to a PC, a
modem (for programming the system using the HiPath 1100 Manager software, and for
enabling CTI features) or a printer (for printing call or configuration data).
.
Consult the ISDN external entrance telephone manual to check available settings
and installation instructions.
Go to the HiPath 1100 Manager folder - Advanced/System Settings/General -
"External entrance telephone" and insert the information on the entrance telephone
device for correct working.
The V.24 serial interface module cannot be used if the system has an ADSL Module
installed.
Additional electronics built into the cables provide level adaptation. V.24 operation
requires level adaptation.
If it is necessary to use another serial cable as an extension to connect the comput-
er/printer/modem to the HiPath 1100, the maximum total length should not exceed
15 metres.
