DCP Extension	The switch data port extensions used for the AUDIX DCP network ports. System 85
Numbers	and DEFINITY Generic 2 traditional modules require four extensions assigned in a
	hunt group. Make the hunt group accessible to Direct Inward Dialing (DID), DCS, or
	tie trunks (DID is the most common). Generic 2 universal modules require at least a
	TN366B vintage 2 ACC, a TN539 vintage 4, or a TN539B ACCE in the AUDIX
	system in order to support four channels.
	System 75, System 75 XE, Generic 1, Generic 3, and MERLIN II require two
	extensions. If the Generic 2 universal module is connected to a TN366 or TN366B
	vintage 1 ACC, it is also limited to two extensions.
RS232	The RS-232 numbers refer to the new ports (channels 5 and 6) available in R1V5 or
Connectivity	later AUDIX systems equipped with a TN539 or TN539B ACCE. Two extension
Extension	numbers are required and should be in their own hunt group with a DID number as the
Numbers	lead extension.
	This field refers to analog RS-232 connections where the AUDIX system is to be
	accessed via a switched RS-232 connection (that is, the AUDIX system will be cabled
	to a switch port through a modem). This is specified as an rs232a (asynchronous)
	type of connection on the AUDIX system : translation : network
	port form.

NOTE

If one AUDIX system is directly connected to another through a null-modem cable, no switch extension numbers are necessary.

RS232	The RS-232 numbers refer to the new ports (channels 5 and 6) available in R1V5 or
(Converted to	later AUDIX systems equipped with a TN539 or TN539B ACCE. This field refers to
DCP	digital RS-232 connections where the AUDIX system is to be accessed via an
Connectivity)	MPDM/M1* or 7400A data module. This is specified as an rs232s (synchronous)
Extension	type of connection on the AUDIX system : translation : network
Numbers	port form.
Hunt Group	On System 75, DEFINITY Generic 1, or Generic 3 systems, this is the soft extension
Extension	(DID) number used to access the AUDIX network hunt group. Typically only one
Number(s)	hunt group is assigned.
Equipment	This is the equipment location code for the DCP and/or RS-232 ports (formerly called
(Switch Ports)	the Equipment Line Location).
Dial String	At times it is appropriate for AUDIX to use the switch’s routing features. Select any
	that apply to your switch and indicate the Feature Access Code (FAC), Trunk Access
	Code (TAC), or Trunk Group (TG) as required.
Switchroom	DID telephone number of the switch room. This number is used to contact the
Number	technician.
AUDIX Remote	The Remote Maintenance Terminal (RMT) DID number assigned to the modem
Maintenance	connected to the AUDIX maintenance port H00. This allows remote services
Number	personnel to log in for troubleshooting and/or administration.
