1.DESCRIPTION

ETl NUMBER: MK-017 D,ATE:APRIL, 1990

This Engineering Technical Information (ETI) Bulletin describes the steps necessary for connection and operation of a Viking Fax Jack III and a Viking PathFinder (Phone/Data/Fax Switch) with the Electra Markll. Both products can be used for the connection of fax machines, modems, and other data transmission devices. By connecting these units to an incoming CO line, Voice calls can be routed to the Electra Markll. However, FadData calls will be directed to appropriate devices. Thisallows multi-use of a CO line.

2.CONFIGURATIONS

Both products must be connected to the Electra Markll via a COI-E/EB ETU pot-t. Fax machines, modems, and other data transmission devices are then connected directly to the Viking products. Fax machines may be G1, G2, G3, etc., type machines. An incoming call from a fax machine that provides CNG tones will be automatically routed to the fax that is connected to the Viking product. An incoming call from a fax machine that does not provide CNG tones will not be routed automatically. The call must be taken via telephone and transferred to the fax machine by depressing “#,l” on the same line that the call came in on. Refer to the Viking Tchnical Practice Notes that are provided with each of these products.

NOTE: Carrier Tone must be sent before incoming modem calls that are to be directed to the modem that is connected to the Viking product. This can be accomplished by the digits dialed by the incoming modem, followed by three pauses, then a string of 2s (a minimum of three 2s is recommended). The string must be longer than the time required by the Telco to connect and ring the line.

If Carrier Tone is not sent, the call must be taken by telephone and transferred to the modem by depressing “#, 2” on the same line that the call came in on.

3.PARTS REQUIRED

For connection of either the Viking Fax Jack III or the Viking PathFinder:

COWEB ETU

Viking Fax Jack III (Model FAXJ-300) or Viking PathFinder (Model PDF-l)

Modular Line Cords with RJll Connectors

NOTE 1: The Fax Jack III comes with a line cord to connect to the COI-E/EB port. Two additional line cords with RJll connectors, allow connection of additional devices.

NOTE 2: The PathFinder requires one line cord to connect the unit to an COI-E/EB port. A maximum of three additional line cords, with RJll connectors, allow connection of additional devices.

NOTE 3: Calls from Fax machines may require longer timers for CNG tones.
