ANNEX A.

Special Characters Used When

Writing Dialing Instructions

These characters perform special functions when embedded in any dialing string:

&-This is a flash-hook which is critical for signaling on analog systems.

,-The comma is a one second pause.

\-The backslash is a four second pause.

T-„T‟ tells the port to switch to tone (DTMF) dialing. This is the default.

W-Wait for answer. On encountering this character, the SVMi-20i will monitor the line for an

answer from the called station before dialing any additional characters. If no answer is

detected within 6 ring back cycles or 3 busy cycles, the call will be recalled.

;-The semicolon is wait for dial tone. The SVMi-20i will wait up to twelve seconds for dial

tone before dialing any additional characters. If no dial tone is detected, the call will fail. This

is useful in environments that may have a shortage of resources such as a limited number of

trunk lines or DTMF receivers.

~di-This is an instruction to dial in band.

H-Operate the hookswitch. If on, hook goes off, if off, hook goes on.

To tell the SVMi-20i to dial the value of a register, you would put a dollar sign ($) in front of

the register variable. I.e., $C means dial the value stored in the Caller ID register. $F means

dial the value stored in the Forward Id register.
