Chapter 5. Using the Terminal Menu5-48 ATLAS_ 800PLUS User Manual 61200226L1-1Quad T1/PRI Module (User Termination/RBS)When you are working in the User Termination section of the Dial Plan menu, theSlot is defined as a T1/PRI module, and Sig is set to RBS, the following configura-tion options are available:First DS0/Number of DS0sWrite security: 3; Read security: 5Defines to ATLAS the DS0s which will be used for this end point. These are theDS0s which will be used by ATLAS to send and receive calls to and from Userequipment (PBX). The incoming calls which will be accepted and the outgoingcalls which will be restricted over these DS0s are set by the Incoming Call Acceptand Outgoing Call Reject Numbers discussed earlier.DS0s AvailableRead security: 5Indicates which DS0s of the T1 have been defined in this switched end point(indicated by “! “), in another switched end point (indicated by “s”), or in a Dedi-cated Map (indicated by “n”).Signaling MethodWrite security: 3; Read security: 5Defines to ATLAS the type of signaling to be used across this trunk. The signalingselected needs to match that being used by the user equipment (PBX).The choices are:• E&M Immediate• E&M Wink• Loop Start• Ground StartATLAS converts signaling types between Network and User Terminations.digits 0—9 This DS0 is available. The digit that displays in this fieldrepresents the last digit of the DS0 number.* This port is requesting this DS0 for this connection, but theDS0 is not yet activated.!
