ADTRAN 550 user manual Dual T1/PRI Module User TERMINATION/RBS, Signaling Method

Chapter 11. Dial Plan

DUAL T1/PRI MODULE: USER TERMINATION/RBS

	When you are working in the user termination section of the DIAL PLAN
	menu, when SLT is defined as T1/PRI-2, and when SIG is set to RBS, the fol-
	lowing configuration options are available:
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.
DS0S AVAILABLE	Read security: 5
	Indicates which DS0s of the T1 have been defined in this switched endpoint
	(indicated by “! “), in another switched endpoint (indicated by “s”), or in a
	dedicated map (indicated by “n”).
	0-9This DS0 is available. The digit that displays in this field represents
		the last digit of the DS0 number.
	* This port is requesting this DS0 for this connection, but the DS0 is not
		yet activated.
	!	This DS0 is used by this endpoint.
	s This DS0 is used elsewhere in the switched DIAL PLAN.
	S This DS0 is in the switched dial plan and conflicts with this endpoint.
	n This DS0 is used in one or more DEDICATED MAPS.
	N This DS0 is in one or more DEDICATED MAPS and conflicts with this
		endpoint.
SIGNALING METHOD	Write security: 3; Read security: 5
	Defines to the ATLAS 550 the type of signaling to be used across this trunk.
	The selected signaling must match that being used by the user equipment
	(PBX). The choices are as follow:
	•	E&M Immediate	•	E&M Wink	• Loop Start
	•	Ground Start	•	Feature Group D

The ATLAS 550 converts signaling types between network and user terminations.
