Loading or Modifying Network Data (after entering the SPID)
This section explains how to use the KEY-ATTR feature in menu mode to load
or modify network data. Enter network assignments using KEY-ATTR if the
set is connected to a switch that does not support the telephone downloading
function.
If the switch has downloaded network data automatically, use these
procedures to modify the set configuration to conform to the desired personal
preferences. In these procedures, select a button on the telephone and assign
the button as a Directory Number, Call Appearance Number, Intercom or
3
Group Intercom Number, or a Feature Number recognized by the network.
In a power failure, data on a reconfigured telephone may be restored to the
original configuration.
Configuration Types: EKTS and CACH
National ISDN (NI) supports two configurations on multiple line sets. The
configurations are Electronic Key Telephone Systems (EKTS or ACO) and Call
Appearance Call Handling (CACH).
EKTS and ACO use Directory Numbers for telephone lines and feature numbers
for features. Enter these numbers with options 2 and 3 of the KEY-ATTR
manual process. CACH uses Call Appearances for telephone numbers and
feature numbers for features. Enter these numbers with options 1 and 2 of
the KEY-ATTR manual process.
