ADTRAN Atlas 550 Manual: Essential Dial Plan Configuration Guide

Chapter 11. Dial Plan

STRIP MSD	Write security: 3; Read security: 5
	Strips a selected quantity (choose from NONE, 1, 2, and 3) of the Most Signif-
	icant 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
	STRIP MSD set to 1. Then, 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.
SOURCE ID
	Write security: 3; Read security: 5
	Simplifies the creation of a DIAL PLAN in applications where the criterion for
	switching calls to a certain endpoint is a function of which endpoint origi-
	nated the call.
	• Default value = 0. The default ID for all endpoints is 0 and all accept
	numbers is 0. With default values, all calls are routed based only on the
	dialed number.
	• Multiple endpoints can have the same SOURCE ID.
	• When creating the CALL ACCEPT list, specify a SOURCE ID(s) as well as a
	dialed number or range of dialed numbers to accept.
	Example:
	An application requires that all calls that originate from Port 1 of the
	ATLAS 550 in Slot 1 be switched to Port 2 of that same module. Assign a
	unique Source ID (e.g. 7) to Port 1 of the module, and then configure Port 2
	to only accept calls from that unique Source ID (7).

DUAL T1/PRI MODULE: USER TERMINATION/PRI

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

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