Toshiba Release 4.0 manual Emergency tab, Using standard 911 service with Strata CS

You may want to consider increasing the dialing service ambiguous timeout by half-second intervals if users report intermittent problems hearing “Number not available” when they dial out on analog or Robbed Bit T1 trunks (this is not a problem for ISDN or IP lines).

If you increase this timeout by too much, you can introduce other problems, such as users missing the beginning of the audio signal at the target, for example, the beginning of an auto attendant that answers calls immediately. If this problem occurs, you can do any of the following:

n

n

n

Reduce the dialing service ambiguous timeout.

Instruct users to enter # after dialing a number.

Collect all digits before dialing (see page 8-10).

Strata CS supports two kinds of emergency dialing services—standard 911 and Enhanced 911 (E-911).

Using standard 911 service with Strata CS

A standard 911 call does not require any additional hardware. All standard 911 calls use a Strata CS trunk and go through the local phone company to the emergency dispatching center.

To support 911 calls in Strata CS, you must provide an emergency access code for users to dial.

Using extended 911 service with Strata CS

An extended 911 (E-911) call includes the calling station’s ANI information (the Strata CS station ID). This information helps the phone company’s E-911 center identify the location of the person who made the emergency call, for example, the specific floor and office in a large building.

An E-911 call does not use a Strata CS trunk. Typically, a dedicated trunk connects the E-911 device directly to the emergency dispatching center.

All E-911 calls go through an E-911 device. For information about obtaining, installing, and configuring an E-911 device, see Strata CS Installation & Maintenance Manual.

After the E-911 device is installed and configured, you must enable E-911 and assign E-911 stations. You assign one or more Strata CS stations for the exclusive purpose of handling E-911 calls. An E-911 station is physically connected to a port on the E-911 device, and can be any station that is not already assigned and that has a valid station license.
