
The VM_5 setting of a general mailbox may include two parts: the first part specifies a pager
number; the second part may or may not specify a Personal Identification Number.

A pager number must not include any *, #, A, B or C because either of them will cause the
system to start Step 5.

A Personal Identification Number must begin with a *, #, A, B or C. A digit of C (entered by
pressing * 4) represents an XX-second pause, the length of which is specified in SYS_2_0 .

Usually, the System Callback Number is a telephone number to inform pager owners to
telephone the EVM system. It will be not sent out if a Personal Identification Number is sent
following the pager number.
External Phone Notification
To deliver the Notification greeting ( paragraph 22 ) to a personal external phone, EVM will take the
following actions:
1. Establishes the connection of access to the PBX by using an idle port (L2 or L4).
2. If SYS_4_5 _[2] is specified, waits one second and then starts Step 3. If not, starts the dial tone
detection:
- If a tone is detected, start Step 3.
- If 3-second silence is detected, abandons the following actions and plays the main greeting as
receiving an incoming call.
3. Dials the C.O Trunk Group Access code specified in SYS_6_5 .
4. Waits two seconds and then dials the phone number.
5. Waits for the Tone Detection delay specified in SYS_7_3 .
6. Handles the call, according to the result of the tone detection:
- If the busy tone is detected, hangs up.
- If the ringback tone is detected, monitors the successive ringback tone cycles. Plays the
Notification greeting (
paragraph 22 ) when the mailbox owner answers. Hangs up when the
ringback tone continues for 30 seconds.

SYS_3_3 determines the maximum number of External Phone Notification attempts. The
