ST Initialisation/Reset
1. To program the ST, depress the reset switch, (Type2 PSU = SW4, Type 4 PSU =
SW2), in the PSU for approximately 3 seconds. LED D8 will begin flashing to
indicate the CRU initialising and self test sequence.
2. After approximately 10 sec, the CRU initialising and self test sequence will be
complete and the LED will be extinguished. LED D9 will still be illuminated.
3. Should the above sequence not be successfully executed, replace the faulty ST.
Programming Sequence
1. With the telephone handset on-hook, depress the Programming switch (Type2
PSU = SW3, Type 4 PSU = SW1). Lift the telephone handset Off-Hook and wait
for the 3 sec continuous “programming start” tone of 1400 Hz, to be heard in the
handset receiver.
2. Lift the handset, a steady tone for 2 seconds should be heard to confirm that the ST
is ready to accept programming information. Enter the respective ST programming
code (or option code) on the telephone keypad, within 40 seconds of depressing
the install switch.
Code Acceptance
1. Should an incorrect programming code be entered, an “incorrect code” tone shall
be heard in the handset receiver, which consists of 1400 Hz pulses for less than 1/2
sec on, and less than 1/2 sec off, for a duration of 5 sec.
Note: If the code is not accepted it may be because the CRU has been programmed
with the two digit RF code where a 3 digit code is needed or Vice Versa.
2. Ensure that at the end of the programming sequence, the “code accepted” tone is
heard in the handset receiver, which consists of 1400 Hz pulses for 1 sec on; 1 sec
off, for a duration of 5 sec.
3. Replace the telephone handset.
4. If the ST fails to accept the programming code after a second attempt, confirm
with the network planning staff that the correct code is being used.
5. Should the ST still fail to accept the code, the ST will need to be replaced.
