Difference Between RJ45 and RJ48 | Difference Between

Just make sure that you wire your connectors properly to what the hardware needs so that you have a working link. Summary: 1.RJ45 and RJ48 use the same connector 2.RJ45 differs from RJ48 in the way they are wired 3.RJ45 is predominantly used in LAN while RJ48 is more commonly seen on T1 lines 4.RJ45 is connected with UTP cable while RJ48 uses STP

T1 lines use another wiring for the same connector, designated RJ48. Ethernet over twisted pair (10BASE-T, 100BASE-TX and 1000BASE-T) also use a different wiring for the same connector, either T568A or T568B. RJ48, T568A, and T568B are all designed to keep pins close together for pairs 3 and 4.

Pinout of CSU/DSU Network, T1, Fractional T1, T3 line RJ-48 and layout of 8 pin RJ45 (8P8C) male connector and 8 pin RJ45 (8P8C) female connectorused to connect a Bridge or Router to a 56K, CSU/DSU Network, T1, T3

56K CSU/DSU RJ-48S Connector. To connect a Bridge or Router to a 56K, CSU/DSU Network, T3, T1 or Fractional T1 line, use a cable with an RJ-48S jack connector. The RJ-48 connector may look very similar to an RJ-45 connector found on a typical CAT-5 cable, but don’t be fooled, they are very different in many ways.

T1 Cable can be a RJ48 or a simple RJ 8 pin depending on the correct wiring . RJ48C. UNIVERSAL SERVICE ORDER CODE (USOC): RJ48C. Mechanical Arrangement: Miniature 8-position jack. Typical Usage: 1.544 Mbps digital services. Electical Network Connection: T&R, T1 R1, conductors 7 and 8 provide cable shield integrity.

Key Difference: RJ, short for Registered Jack, is used in telecommunications systems. RJ45 is a connector designed for Ethernet Networks where 4 pairs of copper wire are used, signaling on RJ45. On the other hand, RJ48 is a registered jack, which is used for T1 and ISDN termination.

Jon thank you for your article How to – T1 Circuits and Wiring, I am currently preparing to extend T1 connections from the Demarc to equipment at several locations. Paperwork that I have received from a third party that will be part of my MPLS network reads “ Demarc (RJ48S) to be located in TELCO Room” which refers to a Verizon tech bringing in the T1 to the building.

The jack panel will have RJ-45 looking connectors called RJ-48C connectors with numbers corresponding to the line cards in the NIU/smart jack. The RJ-48C or RJ-48X is the Demarc! The difference between an RJ-48C and an RJ-48X is; the RJ-48X has shorting blocks that short over to create a mechanical loopback at the female jack receptacle.
