DUAL T1/PRI MODULE: NETWORK TERMINATION/PRI

One HDLC resource is used by each PRI or each Packet Endpoint.

When you are working in the network termination section of the DIAL PLAN menu, when SLT is defined as T1/PRI-2, and when SIG is set to PRI, the fol- lowing configuration options are available:

SWITCH TYPE	Write security: 3; Read security: 5
	Defines the type of PRI switch to which the port is connected. If connected
	to another ATLAS 550, both need to be set to the same switch type. The fol-
	lowing options are available:
	•	Lucent 5E	•	Northern DMS 100
	•	National 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 OUT#ACCEPT (see page 11-3) and OUT#REJECT
	(see page 11-5).
NUMBER OF DS0S	Write security: 3; Read security: 5
	Specifies the number of DS0s ATLAS 550 uses for this endpoint.
OUTGOING NUMBER	Write security: 3; Read security: 5
CONVERSION	Converts outgoing (towards the network) numbers to the selected number-
	ing plan and type option.
AS DIALED	Sends the digits provided as an unknown number type.
ISDN-NATIONAL	Regardless of what type of number is received, the outgoing number is sub-
PREFERRED	stituted with ISDN-National as the number plan and type. Ten digits are
	always sent to the network. Leading ones, if present, are stripped out and
	the area code (provisioned under DIAL PLAN/GLOBAL PARAMETERS) is
	added, if only seven digits are supplied. This action may be required in
	areas with ten-digit local dialing.
ISDN-	Examines the incoming number and if seven digits are received or if a ten-
SUBSCRIBER	digit number is received with an area code that matches the area code pro-
PREFERRED	visioned in the global parameters, the number is forwarded to the network
	as a seven-digit number defined as ISDN-Subscriber number plan and type.
