System Connection
With the addition of the optional System Inter Connection Card, two Digital Super Hybrid
Systems can be connected together to double the capacity of the system. The two systems
function as one, therefore, some functions such as paging and music-on-hold are duplicated.
ISDN Line Service
The system can manage a call received from the ISDN line by point-to-point or point-to-multi-
point configuration. To use this service, an optional unit is required.
TIE Line Service
A TIE line is a privately leased communication line between two or more PBXs, which
provides cost effective communications between company at different locations. To use this
service, an optional unit is required.
E1 Line Service
An E1 line is at the bottom of the digital transmission hierarchy. The E1 line contains 30 voice
channels. Voice is digitised by Pulse Code Modulation. To use this service, an optional unit is
required.
Available for the KX-TD1232 only.
