The DCB E-Extender is a 4-wire repeaters for use on customer owned lines or to extend telephone company demarcs. The Extenders are used to extend in-house E-1 lines in campus and high-rise environments.

Note: This product is NOT intended for 10BaseT or Ethernet. E1 modulation is designed for use with twisted pair solid wire phone cables. The E-extender does NOT extend ethernet connections... only E1 connections.

Each pair of E-1 Extenders may be located up to 4000 feet apart. The Extender circuitry is rated to -43 dB dynamic range at the E-1 rate of 2.048 Mbps. As implemented, the parts are slightly de-rated to provide long life at extended temperature range. Therefore the distances specified in this document are only 4000 feet. Solid copper 22 or 24 AWG, two twisted pair is the preferred cable for connection between the Extenders. Connection to the Extender is made through RJ-45 modular connectors or 4-wire screw down barrier strips. Each Extender comes standard with two screw down barrier strips and one RJ-45 connector. If only RJ-45 connections are desired, extra RJ-45 adapters (part number 9502122) may be ordered.

The 120/240 VAC E-Extenders are powered by a small wall-mount transformer. The Extenders are designed for connections between E-1 equipment such as PBXs, E-1 multiplexers, E-1 line drivers, CSUs, routers or any other E-1 equipment requiring long customer owned cable runs. E-Extenders may be used to connect this equipment across a campus, between floors of a high-rise office building or between office buildings with underground cable runs. The E-Extenders are transparent to the type of data sent over the E-1 link. The data can be D-4 format, ESF, PRI, G.703, G.704, etc.

The Extenders are most often used in pairs to extend a telephone company demarc. For example, if a CSU or DSU is limited to 655 feet and is connecting to a phone company smart jack demarc which is limited to 655 feet, the E-Extenders are used in pairs to extend that distance up to 5000 feet.
