II.4. EXTERNAL ANNOUNCEMENT SYSTEM
Any external announcement system can be connected to MS224 through the 4-pin
RJ socket (the same socket used by DY01 doorphone) on MS224 CPUKON card.
II.5. AUTO-ATTENDANT & VOICE MAIL - EVM224
EVM224 Auto Attendant guides the external callers throughout their calls with pre-
recorded messages, and hence enables the operator to work more efficiently,
especially under high traffic. Optionally, Voice Mail facilities may be employed, and
then the extensions can have private voice mail boxes to be used to leave / receive
messages to / from other users.
EVM224 has 2 minutes Auto Attendant memory on board. Besides, EVM224 has
two 36-pin connectors on the component side, which are used to install the optional
EVM-FE (Auto Attendant Expansion) and three 24-pin connectors, which are used
to install the optional EVM-DE (Voice Mail Expansion) cards.
The EVM-FE card with a Flash ROM memory chip preserves the special messages
for Auto Attendant purposes. At most two EVM-FE cards can be installed on the
EVM224 card in addition to the onboard one. Each EVM-FE card has a message
capacity of 2 minutes. Thus, EVM224 can have a maximum Auto Attendant
message capacity of 6 minutes. 24 different messages to be used during different
states of call handling of Auto Attendant can be entered. These messages are
retained even when the system power is off.
The EVM-DE card with two Dynamic RAM chips stores messages for the Voice
Mail purposes. At most three EVM-DE cards can be installed on the EVM224 card.
Each EVM-DE card can provide a total message capacity of 15 minutes. Thus,
EVM224 can have a maximum Voice Mail message capacity of 45 minutes. The
capacity per EVM-DE card may be also increased to 20 minutes by programming,
in which case the voice quality is impaired to a certain extent, but the difference
cannot be recognized by human ear. The Voice Mail messages are lost when the
system power is off.
EVM224 supports two voice channels, used by both Auto Attendant and Voice Mail
facilities. That is, EVM224 can serve two users at a time, to record and listen to the
messages. The two LEDs on the card are used to show the states of these voice
channels. At start up, these LEDs blink till the system recognizes EVM224. Then,
each LED stays on while the corresponding channel is idle and stays off when the
corresponding channel is in use.
