Dial Line Jack Types

The Federal Communication Commission (FCC) is a telecommunications and standards organization that specifies a series of registered jacks for use with a dial line network or General Switched Telephone Network (sometimes referred to as PSTN). These jacks are designated as RJxxx-type jacks, where RJ means Registered Jack and xxx specifies the jack series. For example, RJ11 indicates a registered jack from series 11. Sometimes the jack designation is followed by a letter (RJ11C) that indicates the jack housing style. Jacks specified under FCC Part 68 fit into one of the following categories: Permissive (voice) or Programmable (data).

6-Pin Voice Jack (Permissive)

This jack type primarily allows voice signals transmitted across lines designated for voice transmission. This jack type also allows data signals to be transmitted across voice-grade lines.

8-Pin Data Jack (Programmable)

This jack type is designed to ensure voiceband data transmission integrity across an interface cable. The jack is referred to as “programmable” because it contains a resistor that allows the phone company to adjust for the optimum output power level before the DCE is connected to the line. The following jack types can be used with your modem.

Jack Type

Description

RJ11C

This 6-pin modular jack type is the most common permissive data mode (voice) jack

 

arrangement found in the home or office. This jack operates on a single-line bridged

 

tip-and-ring voice or low-speed data application service.

RJ16C

This 6-pin modular jack type is a special permissive data mode jack arrangement that

 

allows use of an exclusion-key telephone.

RJ45S

This 8-pin modular jack type is the most common programmable data mode (data) jack

 

arrangement; it permits the use of an exclusion-key telephone. This jack also operates

 

on a single-line bridged tip-and-ring voice or low-speed data application service.

RJ4MB

This 8-pin modular programmable data mode jack arrangement supports Make Busy

 

operation. Using this jack type, you can make the modem appear to be off-hook to the

 

central telephone office.

NOTE: Jack type is defined to the modem using the Telco option in the TELCO OPT'S menu. For details, refer to “Declaring The Jack Type” section later in this appendix.
