3 This section describes the OMEGA specifications.

Operation

OMEGA is designed to connect a remote end point device equipped with an internal modem to a head end computer when a conventional land line is not available. The interface of the modem within the endpoint device must meet PSTN and FCC-68 requirements and be compatible with all standard TELCO handshake signaling.

Modem Interface

A standard RJ-11 modular jack connector provides the OMEGA’s modem interface. The connection is a standard 2-wire dial line interface that has the following specifications:

Output ring frequency:	18 ± 2 Hz
Ring voltage:	70 volts peak to peak
Maximum ringer’s equivalent:	2.0 B
Dial tone frequency:	450 Hz +/- 50 Hz
Dial tone level:	1.0 Volts +/- 20%
ON/Off-hook current detection:	>4 ma
DTMF detection:	Yes
Pulse dialing support:	Not supported
