and fax has 8 FXS and DID ports. Individual ports on the baseboard
module can be configured for FXS or DID signaling. Adjacent ports should
share the same configuration to avoid impedance setting conflicts. A
change to the impedance setting for one port, changes the setting on the
adjacent port. Paired ports are: 0 and 1; 2 and 3; 4 and 5; 6 and 7.</p>

Signaling support available in DID mode includes immediate, delay dial,
and wink start.</p>

<p class="MsoNormal">Hello,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am thinking about installing a VG224 for about 15 lines at
a public building. I have UCM 6.1 and a Cisco 2801 SRST with 2 FXO ports
both FXO ports are connected to POTS lines and all 911 calls are routed out the
POTS lines. I also have a fire alarm that will be connected to 2 POTS
lines. All components are on a UPS that can handle a power outage of 10
minutes. After 10 minutes all phones would be dead except for the fire
alarm system. I am concerned about 911 during a power outage. If
all the phones are dead in a public building during a power outage is this
illegal? I am not concerned about safety almost everyone in the building
carries a cell phone. I am thinking keeping one POTS line at the front
desk. Any suggestions or information about 911 laws.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thank you,</p>
<p class="MsoNormal">Erik</p>
