The “#5” indicates that the destination number should be inserted here, rather than at the end of the VF translation.

The “#*” indicates that the system should transmit a “*” symbol as the first character of an identification code.

The “12345” represents the remaining characters in the identification code.

Example 3: VF Code = #195, VFN = 104 5554567 ****1234*9

This example demonstrates how a VF might be used in place of a tie trunk group connecting two local PBXs, when you have permission to access the other PBX’s facilities to complete calls.

The first three digits (104) represent the FAC for a CO trunk group.

– The “5554567” represents the number for the other PBX.

The “****” represents a 6 second pause (allows time for the other PBX to answer and return new dial tone).

The “1234” represents a “barrier” (security) code required to access the other PBX’s facilities.

The * represents a 1.5 second pause.

The “9” represents an ARS access code for the other PBX.

Since “#5” was not used within the VFN, the destination telephone number (dialed digits) will be transmitted after this ARS access code.

Accessing a Virtual Facility

Dial access is provided by dialing the VF code (#190-#199, including the “#”), followed by the destination telephone number.

Example:

The user dials the following VF code and associated destination telephone number.

#192 12125551643.

The stored VFN associated with VF code #192 is defined as 2222*333*444.

The first four digits (2222) represent the FAC for a tie trunk group to a remote PBX.

The * represents a 1.5 second pause.

The next three digits (333) represent the security code required by the remote

PBX, indicating that you have permission to access their facilities.

The * represents a 1.5 second pause, as the remote PBX checks the validity of your security code.

The final three digits (444) represent the FAC required by the remote PBX to access their Band 5 WATS trunks.
