110 Connecting Blocks enables you to quickly organize and interconnect phone lines and communication cable.
110 Block system is used in equipment rooms or in remote and intermediate wiring closets to connect voice or data wiring to customer premise equipment. The 110 block improves on the 66 block by supporting higher frequencies and using space more efficiently.

Early residential telephone systems used simple screw terminals to join cables to sockets in a tree topology. These screw-terminal blocks have been slowly replaced by 110 blocks and sockets. Modern homes usually have phone service entering the house to a single 110 block, whence it is distributed by on-premises wiring to outlet boxes throughout the home in a star topology. At the outlet box, cables are punched down to standard RJ-11 sockets, which fit in special faceplates.

In commercial settings, this style of "home run wiring" was already in use on 66 blocks in telecom closets and switchrooms. The 110 block has been slowly replacing the 66 block, especially for telephone usage.

The 110 block is often used at both ends of Category 5 cable runs through buildings, as shown in the image. In switchrooms, 110 blocks are used to connect cables to patch panels. At the other end, 110 connections are found in the modular sockets in faceplates. 110 blocks are preferred over 66 blocks in high-speed networks because they introduce less crosstalk and thus are certified for use in Cat5 systems.

Siemon 110 Blocks

    S110 Connection System

    Siemonís S110 field termination blocks combine category 5e performance with unparalleled installation features and are ideal for use in cross-connect and consolidation point applications. Each kit includes adequate connecting blocks to complete each 25-pair termination strip on the S110 wiring block (e.g. S110AB2-100FT includes five 4-pair and one 5-pair connecting block per 25-pair termination strip or a total of twenty 4-pair and four 5-pair connecting blocks).

    25-, 50-, 75-, and 100-pair blocks are available without legs for mounting directly to walls. If cable routing is required behind the blocks, 50-, 100-, 200- and 300-pair sizes are available with mounting legs. The 50- and 100- pair sizes offer detachable mounting legs to assist in routing cables behind blocks during and after installation.

    S110 Field-Terminated Panels

    S110 panels allow wiring blocks to be mounted directly to a 19 inch EIA rack. Each panel includes adequate connecting blocks to complete each 25-pair termination strip on the S110 block (e.g. S110DB1-100RFT would include five 4-pair and one 5-pair connecting block per 25-pair termination strip, or a total of twenty 4-pair and four 5-pair connecting blocks). Panels without cable managers are available in 100-, 200-, and 300-pair configurations. Panels with cable managers are available in 100- and 200-pair versions.

    Pre-Wired S110 Blocks S700

    Siemonís S700 series blocks provide a simple interface method between 25-pair assemblies and punchdown fields using easily accessible connections. The blocks feature both fields on the face of the block eliminating the need to trace cables or access the rear of the block when making connections. Each block comes with label holders and white designation labels as well as hook and loop hold-downs to secure the 25-pair connectors.
