   Signaling	Select the PRI signaling: PRI signaling, CPE (customer premises equipment) side PRI signaling, network side PRI R2 signaling (For more details about additional settings, see the PRI R2 Settings section.)
   Advanced Options
   Framing and coding options	Specify the type of framing and coding to provision the PRI with your PSTN service provider.
   Clocking options	Select the clock synchronization option for the FortiVoice phone system: Clock sourcing from PSTN network Internal clocking source This option setting does not need to match the one used by your PSTN service provider.

   D-channel signaling format	Select a signaling method for the D channel. This format carries the information needed to connect or disconnect calls and negotiate special calling parameters such as automatic number ID, call waiting, and data protocol. The D channel can also carry packet-switched data using the X.25 protocol.
   Line build out	Select the line build out (LBO). Use LBO settings to adjust the output power of the transmission signal to achieve equal level point (ELP) at the DSX.
   D-channel	Depending on your selection in Type, the default channel numbers are: Full T1: 24 Full E1: 16 Make sure to configure this setting to match the one used by your PSTN service provider.
   B-channel	Depending on your selection in Type, the default channel numbers are: Full T1: 1-23 Full E1: 1-15, 17-31 You can also configure fractional channel numbers. For example, for T1/E1, the channels can be the following: 1-12 2, 3, 4, 9-15 2-4, 9-15 Make sure to configure this setting to match the one used by your PSTN service provider.

   Country	Select the country for PRI R2 signaling settings.
   Max ANI digits	Telephone companies use the automatic number identification (ANI) to identify the directory number (DN) of a calling subscriber. This number allows subscribers to capture or display a caller's telephone number. Enter the number of digits of a caller's phone number that the subscriber phone can capture or display.
   Max DNIS digits	Telephone companies can provide a dialed number identification service (DNIS) that lets the receiver of a call know which number a caller has dialed for an incoming phone call. Enter the number of digits of a dialed call that the FortiVoice phone system sends to the telephone company.
   Caller category	Select the caller type.
   Incoming digits mode	Consult your telephone company about which incoming digits mode to select.
