ADTRAN 550 user manual Network Specific, Facility

Chapter 11. Dial Plan

SWITCH TYPE	Write security: 3; Read security: 5
	Defines the type of PRI switch that the ATLAS 550 is going to emulate. If con-
	nected to another ATLAS 550, both need to be set to the same switch type.
	•	Lucent 5E		•	Northern DMS 100
	•	Nation ISDN		•	AT&T 4ESS
FIRST DS0	Write security: 3; Read security: 5
	Defines to the ATLAS 550 the first DS0 for this endpoint. The ATLAS 550
	uses DS0s, starting with this selection, to send and receive calls to and from
	the network (PSTN). The outgoing calls which are allowed or restricted
	over these DS0s are set by the OUTGOING CALL ACCEPT and REJECT NUM-
	BERS (discussed in the ATLAS 550 User Manual).
NUMBER OF DS0S	Write security: 3; Read security: 5
	Specifies the number of DS0s ATLAS 550 uses for this endpoint.
STRIP MSD	Write security: 3; Read security: 5
	Strips a selected quantity (choose from NONE, 1, 2, and 3) of the Most Signifi-
	cant Digits (MSD) of a dialed number prior to being forwarded out of the port.
	Example:
	A network port could be set to accept all calls beginning with 9 (9$), and
	then with STRIP MSD set to 1, all digits would be sent toward the network
	except the leading 9.
			STRIP MSD does not affect CALL ACCEPT criteria. All of the digits
			(including the MSDs that are subsequently stripped) are used as
			accept criterion.
NETWORK SPECIFIC
	Write: 3; Read: 5
FACILITY	Enables the sending of appropriate information to the PSTN. The default
	for this option is NORMAL, and in this case no Network Specific Facility
	information element is sent. Unless one of the services listed below is sub-
	scribed to, the selection should remain set to NORMAL.
	The list below indicates services that may be subscribed to from the PSTN.
	These services require that specific information (such as a Network Specific
	Facility information element) be sent to the network during call setup.
