Table A-2lists the technical specifications of the manual and Table A-3lists the characteristics of the Autodialer.

Table A-2. Technical Speciﬁcations

Characteristic	SpeciÞcation


Operating mode	Full duplex on 2-wire PSTN.

Data rates	Low speed: 0-300 and 600 bps asynchronous.
	Medium speed: 1200 bps (+1%, -2.5%),
	character asynchronous and synchronous.
	High speed: 2400 bps (+1%, -2.5%),
	character asynchronous and synchronous.

Modulation	Low speed: Frequency Shift Keying (FSK).
	Medium speed: Differentially Coherent Phase Shift
	Keying (DPSK).
	High speed: Quadrature Amplitude
	Modulation (QAM).

Compatibility	WECO 103, 113, 212A, CCITT V.22, and
	CCITT V.22 bis modems.

Digital interface	TTL/CMOS.

Transmit carrier frequency	Originate Answer
	Low Speed: Mark: 1270 Hz		2225 Hz
	Space:1070 Hz		2025 Hz
	Medium speed:	1200 Hz	2400 Hz
	High speed:	1200 Hz	2400 Hz

Transmitter output level	Permissive (-10.5 dBm +/- 1.5 dB).

Line impedance	600 Ohm +/- 10%, transformer coupled.

Line protection	Lightning and transient protection.

Receiver dynamic range	-10 dBm to -45 dBm.

Carrier detect hysteresis	No less than 2 dB.

Clamping	Mark hold upon loss of carrier.

Line disconnect	Abort timer (30 seconds, adjustable).
	Loss of carrier (1.4 seconds, adjustable).
	DTR disconnect (80 ms after DTR is dropped).

Scrambling/descrambling of	High speed only: self synchronizing using
data bits	polynomial (1 + X-14 + X-17) per CCITT v.22.

DTE connector	20-pin double row header.
