Chapter 10.0 Installer Warning
Reverse Numbering (Decadic Signalling)
Decadic signaling should not be used as it is being
progressively phased out of the network. DTMF dial-
ling is 100% available and it should always be used.
Line Grabbing Equipment
This equipment is set up to carry out test calls at
pre-determined times. Such test calls will interrupt
any other calls that may be set up on the line at the
same time. The timing set for such test calls should
be discussed with the installer. The timing set for
test calls from this equipment may be subject to
'drift'. If this proves to be inconvenient and your
calls are interrupted, then the problem of timing
should be discussed with the equipment installer.
The matter should NOT be reported as a fault to Tele-
com Faults Service.
D.C. Line Feed To Other Devices
During dialing, this device unit does not provide DC
voltage to the series port connection and this may
cause loss of memory functions for the terminal
devices (local telephone) connected to T-1, R-1.
General Operation (ringer sensitivity and loading)
This device only responds to Distinctive Alert
cadences DA1 and DA2.
In the event of any problem with this device, it is to
be disconnected. A CPE item connected to one of the
device’s terminal ports may be connected directly in
its place. The user should then arrange for the
product to be repaired. Should the matter be reported
to Telecom as a wiring fault, and the fault is proven
to be due to this product, a call-out charge will be
incurred.
