WARNING: ANTI-STATIC PRECAUTIONS MUST BE
TAKEN WHEN WORKING WITH THE CARDS OR
COMPONENTS OF PIGEON EPABX.
CAUTION: Never insert or pull cards from the equipment
with the "power on" under any circumstances. In fixed
systems, do not pull out or insert any flat cable during
power ON.
2.4 Commissioning checks
Power-up CRYSTAL system and carry out the following
checks:
A) On each extension check:
Internal dial tone
Dialling
Ringing
B) Seize each outside line circuit in turn, dialing 61 for
the first circuit, 62 for the second, etc. & check that
the line seized LED operates.
C) From a DOT extension dial a Jn. number and verify
that calls are successfully landing on the main
equipment and properly transferred to local extensions.
Repeat for all external lines.
D) Switch off the exchange. Check the power fail extension
for external dial tone. These extensions should be able
to dial out and receive respective incoming calls directly.
The exchange once installed and put into operation needs
little routine maintenance. Any line fault can be isolated at
the MDF, and exchange faults can be isolated at the card
level. Faulty cards can be replaced with service cards while
they are repaired at authorised maintenance centre to
minimise system down time.
