Product Information

modular connectors are also commonly used as a microphone connectors for PMR, LMR, and amateur radio transceivers. Frequently the pinout is different, usually mirrored (i.e. what would be pins 1 to 8 in the ANSI/TIA-568 standard might be pins 8 to 1 in the radio and its manual).

It is square in shape, like that of the RJ9 casing. It has a configuration of 4P4C, which means it has four positions and four connectors, exactly like that of rj9.

Six Conductor/Six Position Line Cord Module" (PDF). Bel-Stewart Connector. Bel . Retrieved 3 August 2021. RJ48S is typically used for local-area data channels and subrate digital services and carries one line. It accepts a keyed variety of the 8P modular connector.

Rj22 is very similar to that of Rj9 and has the same dimensions as the plastic case, which is plugged in between two devices. One can see the four-colored connectivity between the wires through the plastic casing.

This wiring pattern is for multi-line analog telephone use only; RJ61 is unsuitable for use with high-speed data because the pins for pairs 3 and 4 are too widely spaced for high signaling frequencies. T1 lines use another wiring for the same connector, designated RJ48. Ethernet over twisted pair ( 10BASE-T, 100BASE-TX and 1000BASE-T) also uses different wiring for the same connector, either T568A or T568B. RJ48, T568A, and T568B are all designed to keep both wires of each pair close together.
