available capacity is 3-6 Co lines and 8-16 station ports. In addition there are 16 virtual extensions.
The

FAX detection capability
.
The following example shows how to program Fax detection.
Z600, Co1, item01= 11, 12, 13
Z118 = 004 Ring the extensions for 4 sec
Z604, Co=01, item03=3 DISA activated for Day and Night
Z400, Group=07, item 03=21 where 21 is the fax extension

ONLY ONE
station card, whether it is an SLT card or a Digital station card can be installed on the left
hand side of the upper deck, marked “HYBRID CARD”.
ONLY ONE
trunk card can be installed on
the right hand side of the upper deck, marked “ ----- CARD” .
IMPORTANT NOTE:
There are many types of station cards ranging from single station to 8 stations
available. However,
ONLY ONE
card can be installed in an expansion card position. Therefore, it is
important to consider the future expansions very seriously before ordering a station card.
Transmission level on trunk lines.
WARNING:
Do not adjust transmission levels unless it is absolutely necessary.
1. Zone 612_CO:xx = "0"~"4" - TX speech level adjust; default is "0" disable and can be increased from
"1"/1dB up to "4"/+4dB.
2. Zone 613_CO:xx = "0"~"4" - RX speech level adjust; default is "0" disable and can be increased from
"1"/1dB up to "4"/+4dB.
The above setting also effects the DTMF signaling, the DTMF sending level increase as well.
Virtual Extensions,
16 of them are very useful for abbreviated dialing and easy to program. The
following example shows how to program a virtual extension 55
Z258, Times=06 Enable virtual extensions
Z610 , DID=83 EXT= 055 - i.e. extension 55
Z404, SPD= 283, item01 = xxxxxxxxxx - program speed dial number in bin 283
When you dial 55 from internal extension or via DISA the call will be forwarded to the mobile phone.
Z225, #0
Note: All SLT on DV22 receive CLI & MW
EnGenius cordless will display CLI when ZONE 502 item 06 = 4 is programmed
Fax detection capability only works if D4VSCD is installed and DISA activated (Not call
queue)
