	Function	Switch	Switch	Option	Description
			Location
	FXS Ports	S14, S15, S16	Internal	3 dB	3 dB: Transmit path attenuated by
	Transmit	positions 2, 4, 6		9 dB	3 dB (+/– .5).
	for 12 port model	and 8			9 dB: Transmit path attenuated by
	(see page 26)				9 dB (+/– .5).
	FXS Ports	S14, S15, S16	Internal	3 dB	3 dB: Receive path attenuated by
	Receive	positions 1, 3, 5		9 dB	3 dB (+/– .5).
	for 12 port model	and 7			9 dB: Receive path attenuated by
	(see page 26)				9 dB (+/– .5).
	FXS Ports	S17, S18, S19	Internal	3 dB	3 dB: Transmit path attenuated by
	Transmit	positions 2, 4, 6		9 dB	3 dB (+/– .5).
	for 24 port model	and 8			9 dB: Transmit path attenuated by
	(see page 26)				9 dB (+/–.5).
	FXS Ports Receive	S17, S18, S19	Internal	3 dB	3 dB: Receive path attenuated by
	for 24 port model	positions 1, 3, 5		9 dB	3 dB (+/– .5).
	(see page 26)	and 7			9 dB: Receive path attenuated by
					9 dB (+/– .5).
	Trunk Conditioning	S6, S7	Internal	Idle	Idle: In the event of an alarm condi-
	(per group of 12	position 6		Idle Imm./Busy	tion in the T1 connection to the net-
	lines)				work, the FXS Ports will be put into
	(see page 28)				the idle state immediately and
					remain in this condition until the T1
					has been restored.
					Idle Immediate/Busy: In the event
					of an alarm condition in the T1 con-
					nection between the ICX-250 and
					the network, the FXS Ports will be
					put into the Idle state immediately
					for 3 seconds and then put in the
					Busy state and remain in this condi-
					tion until the T1 has been restored.
	FXS Ringback Tone	S6-S7	Internal	On	On: Ringback tones will be sent
	(see page 29)	position 7		Off	on the corresponding DS0’s for the
					duration of ringing on the line.
					Off: Ringback provided by PBX
					or Switch.
	FXS Timeslot	S7 Only	Internal	Off	Off: FXS Ports 1-12 are mapped
	Assignment	position 8		Swap	onto T1 timeslots 1-12 and FXS
	(see page 30)				Ports 13-24 are mapped onto T1
					timeslots 13-24.
					Swap: FXS Ports 1-12 are mapped
					onto T1 timeslots 13-24 and FXS
					Ports 13-24 are mapped onto T1
					timeslots 1-12.
					Depending on the services pro-
					vided by your carrier for voice
					and data, you may need to reas-
					sign the FXS timeslots of the 12
					FXS port model. Timeslots 13 to
					24 will be assigned in order to
					allocate data to the lower
					timeslots.
	FXS Ports	S4-S5	Back	On	On: Breaks the connections to
	Loopback Operation	S5 1-12 = 1-12		Off	and from the FXS and loops the
	and/or Channel	S4 1-12 = 13-24			receive data back onto the transmit
	Unassigned				path towards the T1. In the case
	(per line)
					of unassigned channels, provides
	(see page 39)
					an idle termination.
