Basic parameters

The table Basic parameters on page 67 provides a record of basic parameters that are significant for SRG operation. Typically, these parameters are specified as part of BCM50 foundation activities; in most cases, their configuration is not covered in the SRG50 Configuration Guide.

Table 15 Basic parameters (Sheet 1 of 2)

Parameter	Value	Context

DN length		Configured as part of BCM50 foundation configuration.
		There are four DN lengths to consider.
		1. Configuration > Telephony > Dialing Plan > General > Dialing
		Plan - General panel > Global Settings subpanel > DN length
		(intercom) field
		This is the internal DN length. That is, the length of DNs for calls
		between telephones on the SRG.
		2. Configuration > Telephony > Dialing Plan > Public Network >
		Dialing Plan - Public Network panel> Public Network Settings
		subpanel > Public Received number length field
		For calls originating from the PSTN, this establishes the number of
		digits the SRG retains.
		3. Configuration > Telephony > Dialing Plan > Private
		Network > Dialing Plan - Private Network panel > Private
		Network Settings subpanel > Private Received number length field
		For calls originating from a private network, this establishes the
		number of digits the SRG retains.
		4. Configuration > Telephony > Dialing Plan > Private
		Network > Dialing Plan - Private Network panel > Private
		Network Settings subpanel > Private DN length field
		Used for DPNSS applications only. See the Networking
		Configuration Guide (NN40020-603).

DN range		Configured as part of BCM50 foundation configuration.
		DN range of the SRG is set by the hardware configuration and
		keycodes. Actual numbering is contiguous from the Start DN:
		Administration > Utilities > Reset > Reset panel > Cold Reset
		Telephony Services button > Cold Reset Telephony dialog box >
		Start DN field

Destination code		Configured for advanced routing. See Outgoing calls configuration
for VoIP trunks		on page 74
		VoIP destination code = VOIP Trunk Access Code* = AC1**
		* VOIP Trunk Access Code is entered on the main office settings
		panel. See the server-specific chapters for details.
		** For a UDP dialing plan, AC1 is the access code in the digit string
		<AC1> <LOC> <DN>.

SRG IP address		Configured as part of BCM50 foundation configuration.
		Configuration > System > IP Subsystem > IP Subsystem panel >
		General Settings tab > IP Settings details subpanel
